Broken ore equipment
Generally speaking, broken ore equipment and broken mine machinery are used for breaking ore chunks of materials. The granularity of product is thicker, and it usually greater than 8 millimeters. The tectonic characteristics is a certain gap between the broken pieces, and make sure they dont touch each other. Crusher can be divided into fine, medium and coarse.
According to the broken mode and structure, broken ore equipment and broken mine machinery including six types.
jaw crusher : Crushing effect is to rely on moving jaw pressure to fixed jaw periodic to crush the ore.
cone crusher: Within the fixed cone, the inner cone swinging conical as eccentric to crush the ore.
Roll Crusher: The ores are in two opposite spin round roll, they mainly affected by the continuous crush role, but also with grinding strip role, and chopping broken role by tooth-type roller surface.
Vertical Crusher: The ores are impacted and breached by the moving parts in rapid rotation. This kind of broken ore equipment and break the ore machinery including hammer crusher, cage crusher and impact crusher.
Impact crusher: It is using plate hammer of high-speed impact and counterattack board rebound effect to break the materials by repeatedly impact.
Hammer Crusher: Hammer crusher has the following advantages: big crushing ratio, discharging granularity evenly, less excessive smash things, low energy consumption, etc. But because hammerheads wear faster, it is limited in hard material broken; In addition, grate bar easily blocked, so it is unfavorable to break materials with clay and high humidity. Hammer crusher is usually used to crushing limestone, shale, coal, plaster, chalk and other materials under medium harden.
Compound crusher, commonly known as the vertical shaft hammer crusher ,is also a hammer crusher. It applys to building materials, mining, metallurgical and chemical industry to break limestone, clinker, coal and other minerals, and its compressive strength is no more than 140 mpa and humidity is not more than 15%.

Brief introduction to sandstone production line
Sandstone production line is a kind of specialized equipment for standstone of building material and stones, which is 50% advantage than traditional vertical shaft impact crushers in energe-conservation. It can make all kinds of rocks, sandstone, cobbles into sand for building purpose with outstanding features of perfect standy granularity, and very high compression strength, that performs better in meeting the requirement of building than natural sand and the stand produced by common hammer blasting machine, capable of improving the quality of construction. This equipment has the following features: reliable performance, reasonable design, easy to handle, high working effeciency. Manual sandstone production line gets suitable different specification stone by crushing, viberating and screening through feeding machine and jaw crusher , finished stand will be obtained by high effect sand washing machine.
Sandstone production line is defined according to discharging type, manufactured products including building stones and artificial sand,also called building stones production line, to be equivalent to the combination of building stone production line and sand machine. It often needs a shared sand and stone production line in raw material factory for road building and construction site. This set of sandstone production line equipment can fully meet the requirment of producing the building stones and artificial sand.
Following is the introduction to process of sandstone production line:
The stones is conveyed from viberation feeding machine to jaw crusher to make rough crush, the material after rough crushing is sent by belt conveyor to sand machine for further crushing, the precise crushing material is transported to viberation screen for screening, and then the material which have reached the granularity requirement of finished products is carried to sand washing machine for cleaning, after cleaning the finished products comes off the conveyor; those not meeting the granularity requirement will be reworked back from viberation screen to sand machine, forming a closed manifold cycles. The granularity of finished products can be combined and classified according to customersâ requirement. If choose to use dry manufacturing techniques, coarse powder and fine powder splitter, and dust-removing equipment can be prepared.

If you want to trace the developing history of ore crusher, the old pestles invented by our ancestors are simple rudiments, though it is a very simple crushing tool,it has the certain crushing function. so, it is not too much to say that the old pestles are crushers ancestors. To the time 200 BC~100BC, feet operating hammer appeared, this tool had already equipped with the basic function of a crusher,due to the using of lever principle.
Modern crusher was developed from the western industrial revolution. In 1858, jaw crusher was born in the United States, it was designed and manufactured by an American named Blake.Its structural form is double- elbow -plates jaw crusher . Jaw crusher can be used in coarse crushing process, and can also be used in medium and fine crushing process,especially in underground crushing assignments and medium and small mobile crushing devices.
impact crusher emerged in time of the second world war, it is a crushing equipment with new style and high-efficient.The first impact crusher designer is Doctor Henderson. It can be used for cement,asbestos,glass,chemical industries and do coarse ,medium,fine crushing. Impact crusher can be divided into the single gear impact crusher and double gear impact crusher, whose specifications is defined by rotor diameter and length.
The worlds first cone crusher is primary designed by American Symons brothers.Till now, many domestic manufacturers of cone crusher name their crushers Symons. It is about 1920 that symons cone crusher applied in crushing mills. In 1948, an American company researched and developed the hydraulic cone crusher, It can expel the uncrushable materials that entered into the crushing cavity, and can adjust the discharging mouth size during operating, producing the granularity with a uniform size. To the 1970s, along with the development of technology, automatic controller has been developed to be used to control the hydraulic cone crusher.Cone crusher has advantages of big crushing ratio, high efficiency, less energy consumption and uniform granularity size.Suitable for medium,fine,and superfine crushing of hard rock and ore materials.
The first patent of gyratory crusher was applied by American Charles Brown in 1878, and the first gyratory crusher was sold in 1881 by the Chicago Gates iron factory. Gyratory crusher is widely used in large and medium-sized sand processing mills and large quarrys, for coarsely breaking various hardness of rock and ore materials.
With the development of science and technology, the crusher equipment has made great progress till today. Especially after the nineties, the sales of crushing machinery are growing rapidly, corporations that joined the crushing industry are increasing unceasingly,The number of crusher manufacturers has reached more than ten thousands, We can produce comparatively complete series products,such as 0.5 ~ 30t crusher , 4 ~ 24t static crusher and 16 ~ 30t mobile crusher, and basically formed independent research and development system that produces a complete crusher equipment,the gap between our technical level and the international advanced level is decreasing gradually. This kind of high-speed growth situation, certainly will push the industry of crushing machinery fittings and wear parts to a new stage.
Bico Chipmunk Jaw Crusher Maintenance
The Bico Chipmunk jaw crusher is designed to give long and efficient service. In order to secure the long life and excellent performance that your crusher is capable of delivering it is essential that the following directions for operation and maintenance be carefully observed.
MECHANICS OF ITS SUCCESFUL DESIGN
The upper end of the jaw travels in a circular path driven by the eccentric shaft. The lower end oscillates through a short arc described by the toggle. The resultant jaw action is forward and downward motion relative to the stationary jaw that crushes the sample and forces its discharge.
The discharge opening between jaws can be adjusted to control crushed particle size by turning the hand wheel on the side of the crusher. The adjusting mechanism consists of steel wedge blocks operated by a screw. The wedge blocks transmit crushing forces from the jaw to the frame relieving all strain on the adjusting screw itself. The stationary jaw is simply lifted out of the frame to completely expose the inner parts for thorough brushing and cleaning. Dropping the cam-lock handle securely anchors the jaw.
Jaw plates are tough, thick steel and are reversible end for end for double wear. Heavy bronze bearings are sealed against dust and dirt and are lubricated by grease cups, so that no special greasing tools are required.

JAW CRUSHER INSTRUCTIONS
The Flat Faced Pulleys on the VD and WD crushers as run with V-Belts is a specially engineered arrangement for these machines. This combination has been in use for many years in the manufacture of this crushing equipment and has proven to be the very best arrangement for machines such as these. When equipment is confronted with a SHOCK LOAD condition, this v-belt/flat pulley arrangement allows just enough give, thus preventing undue strain on the key, flywheel and eccentric shaft.
Manganese Steel plates are available on special order. It is recommended that only one plate, preferably the Stationary plate, be of this material. Two Manganese Steel plates will not reduce hard ores satisfactorily because there is insufficient grab between the surfaces. Manganese plates are wear hardened with impact and heating.
JAW CRUSHER INSTALLATION
Unpack your Crusher and set it on a platform in the desired location. Insert the mounting blocks under each side of Crusher to raise the unit and allow clearance for the ore pan. Securely bolt to platform. Check the alignment of v-belts from the grooved motor pulley to the flat-faced pulley. This alignment is critical as it is only the alignment that keeps the belts on the Flat-faced Drive Pulley. ROTATION IS CLOCKWISE WHEN FACING THE DRIVE PULLEY.
Connect the relay switch to your power source in accordance with the directions enclosed with the switch. Just above the junction box on the motor is a direction plate indicating the proper wiring for your current. Connect the Crusher to the relay switch in accordance with these directions. AGAIN, ROTATION IS CLOCKWISE WHEN FACING THE DRIVE PULLEY.
The magnetic starting switch has internal overload protection. This shuts off the current automatically should the Pulverizer jam through improper adjustment of the plates or the introduction of foreign matter into the grinding chamber. Should an overload occur, wait a few minutes to permit the relay to cool and then press the RESET button.
The jaws are preset at the factory to a gap of 1/32″. Before starting the crusher for the first time, the gap should be checked to see that this space has not been altered in shipping or setting up the machine. A tighter gap could result in damage to the machine.
The crusher can be adjusted by loosening the jam nut and setscrew on the left hand side and turning the adjusting screw on the right side of the machine. Turning the flywheel located at the right side of the machine to the left or right will open or close the space between the lower parts of the jaw so as to give the required crushing size. DO NOT SET THE JAWS TIGHTLY TOGETHER as this will result in damage to the machine (minimum allowable opening is 1/32 inch on forward stroke of movable jaw).
ADJUSTMENTS
Heavy bronze bearings are sealed against dust and dirt, and are lubricated by grease cups so that no special greasing tools are required. To tighten the bearings, loosen the two square headset screws (behind the cap) a fraction. Turn the four hex-head bolts down a fraction at a time. Check tightness by turning the pulley or flywheel by hand. There should be a very slight drag. To loosen, reverse the procedure. Bolts must be tight, but not too tight. USE EXTREME CAUTION AS OVER-TIGHTENING THE SQUARE OR HEX HEAD SCREWS WILL BREAK THE CAPS. The caps will radiate some heat, which is normal. Bearings should not be run loose or excessive wear will result on the bearing, shaft, etc. Check the bolts on a regular basis, as the machines vibration will have a tendency to loosen the various bolts.
JAW CRUHSER MAINTENANCE
It is of the greatest importance that the crusher is kept properly lubricated at all times (use any good quality hi-temperature grease. We use a lithium-based grease). Turn down the grease cups 1/4 of a turn at least once a day, or more if the machine is in constant use. This will protect the bearings. Oil the adjusting blocks and toggle block approximately once a week. An oil cup is provided for this purpose at the front of the spacer casting and at the rear toggle block.
When the plates are worn to a point where readjustment is necessary, they can be adjusted. To do this simply insert the set of shims provided with each crusher between the jaw and jaw plate. This will compensate for wear.
For still further adjustment, and for resetting the adjusting blocks, loosen the small setscrew at the left side of the crusher. Turn hand wheel to the right, which will allow the adjusting block to move forward.

Ball mill
The Barmac Rotopactor Vertical Shaft Impactor (VSI) consists of a feed tube, rotor, crushing chamber, a bearing cartridge and a discharge chute. The rotor is driven through multi drive V belts from a 200KW electric motor. The rotor is spinning at approximately 1040rpm. The Barmac is called a rock âShaperâ and not a rock crusher because the 2 main reduction methods used by the Barmac are attrition by glancing blows with other rocks and abrasion as the rocks interact. Therefore the concept of the Barmac VSI is rock on rock shaping.
Ormeau Barmac
Barmac rotopactor vertical shaft impactor
The Ormeau Barmac is set up to have two inputs, one from screen 3, of size 25 â 5mm through chute 3, and the other from oversized material returning to the surge bin for re crush, which is diverted into chute 23 by the adjustable gate 2. Therefore, an input material summary is 25 â 5 mm. Once through the Barmac material travels through transfer point 9 to conveyor 2.
The rock is continuously feed into the feed tube of the Barmac, which directs material into the centre of the high speed spinning rotor, which throws the material out, at a speed of 50-85m/s, as a continuous rock stream into the stone lined crushing chamber. The material size reduction comes from the airborne rock on rock interaction and the rock on rock interaction as the rotor accelerated material hits the material build up on the sides of the crushing chamber.
The material build in the rotor and the crushing chamber are vital components to the Barmac. The rotor and crushing chamber are lined with wear plates but rely on material build up to protect the system from wear from the high speed material interaction. Material once shaped is deposited through the discharge chutes and onto the conveyor belt.
Barmac rotopactor vertical shaft impactor rotor
The rotor is at the centre of the VSI. It is mounted on a bearing cartridge which consists of 2 radial bearings and a trust bearing, with 2 grease seals. The bearing cartridge must be greased daily to the manufactures specifications of 15 grams of grease a day.

Australias largest in-pit crushing system taking shape
Four giant in-pit crushers are taking shape at Citic Pacific minings Sino Iron project at Cape Preston in north west WA. They are being manufactured by ThyssenKrupp, with components being fabricated in Australia, Germany and China.
In terms of installation progress, a spokesman from owner Citic Pacific Mining (CPM) told the AJM in mid- February that âthe first two of four crusher pocket slots are completed and the first in-pit crusher is being installed. The bucket wheel reclaimer installation is almost completed.
In terms of start up date, the first shipment of ore is anticipated towards the latter part of this year.
The in-pit crushers supplied will be gyratory, 60″ x 89″, with a capacity of 5,100 tph. They will be powered electrically by the projectâs combined-cycle gas-fired power station and have been integrated into the mine design.
A number of other factors were taken into consideration during the design phase, including the rigidity of the conveyors, energy needs due to the depth of the pit, the layout of the infrastructure, the width of the haul road and traffic management needs.
CPM deputy director operations Andrew Thomson said progressive run-of-mine pads and conveyor paths were designed into the pit. âWhen ready the crushers are un-coupled and moved to the new location using crawler units. They are effectively âplug and play installations and although it is a significant task it is less onerous than a fixed installation, Mr Thomson said.
After blasting, the crushers are fed by a truck and shovel combination. The 200 millimetre crushed ore is then transported by large conveyors to the coarse ore stockpile at the feed end of the concentrator.
ThyssenKrupp invented mobile crushing technology in 1956 and the firm is today a leader in in-pit crushing systems, having supplied over 200 worldwide.
A senior processing engineer from ThyssenKrupp Materials Handling spoke to the Australian Society for Bulk Solids Handling (ASBSH) in February in Perth about the companyâs technology in the area. Christoph Hoetzelâs session was entitled âthe evolution and outlook for ThyssenKruppâs large scale semi-mobile crushing plants.â
There were at least 40 people in attendance and it was an excellent presentation, said Eric Lau, lead mechanical engineer, AMEC Minproc and WA technical convener.
Christophs speech was a joint technical session presented by the Mechanical Branch Engineers Australia WA, the Institution of Mechanical Engineers, the American Society of Mechanical Engineers and the ASBSH.
Artificial Sand Maker

Architectural Sand Crusher
Manufactured sand is mainly used in construction industry. The increasing insufficiency of natural sand makes manufactured sands more and more important. Manufactured sand is also called artificial sand, which was produced by crush the cobble stone or other stone into sand by sand making machine in sand production line. As the basic materials of concrete, cement mortar of architectural sand, Successful application of artificial sand is an indisputable fact that a large number of engineering practices (including the Three Gorges Project) has demonstrated the possibility and necessity of using sand.
Manufactured sand production plant
Regarding of detail condition, two kinds of techniques are usually adopted in producing manufactured sand, dry way and wet way. Both methods can produce high quality manufactured sand as concrete aggregate. Especially, the dry way can produce not only the manufactured sand used in SMA road surface, but also the powder used in asphalt concrete.
The manufactured sand production plant consists by vibrating feeder, jaw crusher , impact crusher, sand making machine, vibrating screen and belt conveyor and other mining crushing equipment. According to different process requirements, various types of mining equipment can be combined to meet the technological requirements of different customers.
Firstly, the stone was broken by primary crushing equipment such as jaw crusher , impact crusher, then, the coarse sand grain was transported by belt conveyor to secondly crusher such as cone crusher for further crush. Then the broken small stone can be screened out the two major sands via vibrating screen, one kind can be transported to sand making machine, the other will be crushed again.
The small stone will be made into manufactured sand by sand making machine, after washing by sand washersï¼optionalï¼, the final artificial sand was made.
Core equipment for manufactured sand production line is sand making machine such as vsi crusher, vsi5x crusher etc. There are three generations of sand making machine produced by our company and each generation has a superior performance and better economic benefits than its previous one.
Vertical shaft impact crusher suitable feed size is required thus primary crushing and secondary crushing is necessary. Vertical shaft Impact crusher has a high energy consumption and water is necessary for manufactured sand production, which the customer should keep in mind.

Antimony Crusher
Antimony crushers, including jaw crusher , ball mill, impact crusher and cone crusher, are widely used in the whole antimony mining process. And mobile antimony crushers are the good equipment choise to most of the animony ore concentrators. Primary antimony crushing is used twice in the antimony process. Shenbang would supply the most suitable antimony ore crushers and antimony mining mills for you.
Application of Antimony
Antimony processing plant
Antimony was recognized in compounds by the ancients and was known as a metal at the beginning of the 17th century and possibly much earlier. Antimony is not abundant, but is found in over 100 mineral species. It is sometimes found natively, but more frequently it is found as the sulfide stibnite.
Antimony is finding use in semiconductor technology for making infrared detectors, diodes and Hall-effect devices. It greatly increases the hardness and mechanical strength of lead. Batteries, antifriction alloys, type metal, small arms and tracer bullets, cable sheathing, and minor products use about half the metal produced. Compounds taking up the other half are oxides, sulfides, sodium antimonate, and antimony trichloride. These are used in manufacturing flame-proofing compounds, paints ceramic enamels, glass, and pottery.

Carbon in pulp (CIP) adsorption
This antimony processing plant is configured for any throughput close to 40,000 TPA â a capacity which reflected the fact very high-grade ore was processed. However, the present crushing units from the plant use a capacity of around 100,000 TPA. Accordingly, from the installing of additional tanks and ball mill, the plantâs throughput can be increased to levels approaching capacity without the need for extensive redesigning. The tailings dam used during previous production may also be expanded to deal with increased plant capacity.
This antimony processing plant operated for a amount of around Half a year before Chase Minerals was forced into administration following a 1998 stock exchange crash. The plant was subsequently operated for an additional 15 months by Fiminston Mining between 2001-3.
This infrastructure will significantly decrease the capital expenditure needed to bring high-grade gold deposits identified over the extent of the Blue Spec and Red Ribbon Shears into production inside a shorter period when compared to a greenfield project.

A typical crusher plant installation
The Jaques cone crusher at the Ormeau Crushing and Screening plant crushes primary crushed material from the jaw crusher , of feed size of approximately 100mm to 50mm, through the use of an eccentric rotation. The rotation occurs only at the bottom of the main shaft. An 110KW electric motor creates the drive to the eccentric assembly through multiple drive V belts. The eccentric assembly turns at a constant speed, causing the lower end of the main shaft to gyrate. The main shaft is pivoted at the top of the main shaft by the spider bearing. The process is continuous.
Jaques cone crusher crushing process
gyratory crusher
After material has passed through the jaw crusher it is feed into the Jaques gyratory cone crusher, which in the system is called a secondary crusher. Crushing occurs when pressure is applied to material which falls in between the eccentrically rotating main shaft wear liner called the mantle against the fixed wear liners called the concave ring and concaves. Due to the eccentric rotation there is a close side between the mantle wear liner and the concave wear liner, and also an open side.
Therefore feed material falls into the crushing chamber and is crushed at the nip points, close side, as the mantle eccentrically rotates around the concave. Some material may fall through the cycle without being crushed on the open side. Material that has passed through the crusher on the open side will be crushed on other cycles. After material, which is now called secondary crushed, falls onto a discharge conveyor and travels to the next stage of the process.
Close Side Setting
The close side distance of the crushing chamber is called the Close Side Setting (CSS). The CSS is the distance from the mantle to the concave at the point where nipping occurs. The larger the CSS, the larger the output rock will be. The CSS can be adjusted and is accomplished by raising or lowering the main shaft assembly. By raising the main shaft assembly, the CSS would decrease.
The open side measurement, on the opposite side of the mantle is called the open side setting (OSS). The OSS is equal to the eccentricity plus the CSS. The adjustment is achieved mechanically. The top of the main shaft assembly is threaded, and so by way of turning the suspension nut the height of the main shaft assembly and subsequently the CSS is adjusted.
As a secondary crusher, it uses a superior mantle and concave, this refers to the shape of these two components. The shape allows for a larger input size of material, while still outputting a well reduced size of rock. This is referred to as the Percentage Reduction. Therefore the percentage reduction of the 900mm Jaques Gyratory Cone Crusher is higher than the tertiary crushing configuration.
Jaques cone crusher oil system
This particular crusher at Ormeau has been modified from the Original Manufacturers specifications. The crusher is lubricated through one simple system. Oil is transferred from the reservoir by the oil pump. The pump is driven by a speed reducing gearbox which is connected to a 5KW electric motor, instead of being driven directly from the main shaft. Oil then enters a filter, and then through an oil cooler. Oil then enters the crusher through the pinion housing. Oil flows through the pinion housing to the crown wheel and through the eccentric assembly. Oil is then gravity feed through a port in the bottom of the pinion housing back to the reservoir.
CRUSHER PROTECTION SYSTEM
The crusher is fitted with protection systems. The crusher motor is electrically interlocked, therefore the crusher drive motor will not start until the oil pump has been started and the low oil flow sensor is not reading low oil flow. The low oil flow sensor is located on the return side of the lube system, and so oil circulates the entire system and is returned back to the tank, before the low oil flow sensor does not read. This means that the crusher has sufficient lubrication and can be started. The interlock now allows for the crusher motor to be started. This interlock also works when operating the crusher; if the low oil flow sensor reads low oil flow the crusher motor will stop, as there is a problem.

Other benefaction
Other forms of benefaction for quality are available to the Producer. These include the log washer, heavy media separator, and attrition mill. The log washer commonly is used in wet operations to agitate and scrub clay and other objectionable fines from coarse aggregate. A Producer may need to use a log washer when rinsing screens do not remove these objectionable fines.
Heavy media separation is somewhat costly, but may be the only practical way for a Producer to meet quality requirements. This method works only when the undesirable material has a different specific gravity than the desirable material. The deleterious material is discarded after the media is separated for recycling.
Attrition mills are seldom used but remain an option when the deleterious particles are uniformly softer than the non-deleterious particles. The attrition mill abrades the deleterious particles into fines that may be screened out of the system.
Screening
Screening is another technique to control both quality and gradation of the aggregate product.
PRODUCT QUALITY
If deleterious material exists at undesirable levels after crushing and may be identified as being predominantly in one size range that is not needed for product size, the material may be screened out (namely, fines or top size). This step may occur between crushings so that an opportunity exists to recreate the same size downstream, if needed, to create a product. The screened-out lower-quality material may be used for a lower quality product or wasted if no use exists.
The rinse screen is also commonly used. By running the material over a screen that retains all of the product, enough clay and deleterious fines to make the product acceptable may be rinsed away.
GRADATION CONTROL
The best technique for gradation control is screening. Screening may be done wet or dry, depending on the kind of aggregate being processed and the degree of consistency required for each product. Washing, for example, may be necessary to clean a concrete aggregate, but may not be needed for hot mix asphalt products, which can contain more fines.
For gradation control alone, however, consistency sometimes may only be maintained by using wet screening, especially for hot mix asphalt products. Gradation consistency is usually an overriding factor for a hot mix asphalt customer. Water volume and flow direction are critical in wet screening. Frequent checking of gradation is a standard operating procedure.
Dry screening is a slight misnomer because the material passing over the screen decks is wet, ranging from slightly damp to very wet, depending on conditions such as rain or subsurface moisture. Non-washed screening is a more accurate description of this screening process. High moisture is a concern because the wet aggregates may cause some material to become sticky and bind together, making the aggregate harder to separate.
Furthermore, high-moisture conditions may cause binding of lower screen decks, causing override of the material rather than separation. If these conditions are encountered, the Producer may need to establish a balance between the moisture content of the incoming material and the feed rate through the screens. This balance is required to be made for each hour of operation. If reduced feed rates do not solve the problem or is too costly, washing or an additional screen area may be needed.
Sometimes screening variation is too great even under the most favorable of conditions. When this occurs the Producer is required to check that the equipment and the screen cloth are in good repair. The most common reason for high screening variability is the tendency to push too much material over a screen. The only way to maintain a bed of material thin enough for optimum efficiency is to provide enough screening to allow the desired rate of production. Standard operating procedures should reflect the maximum feed rate for the design of the plant.
For well-graded products having many sieves, (namely, #53s), gradation control may not be done without first separating the material into fractions. Separating the material into numerous small fractions and then back-blending at a set rate for each fraction may be necessary to control the gradation. Frequent sampling, testing, and control charting are necessary for monitoring because aggregate gradation is subject to so many variables.
