Crushing plants must be designed for ease of access and maintainability if they are to meet their production goals. Keeping maintenance requirements to a minimum helps achieve higher overall operating availability. Scheduled preventive maintenance at crushing plants involves a number of elements, including:
⢠Crusher wear parts ⢠screen decks ⢠feeder wear parts ⢠conveyor skirting and adjustment ⢠Oil and lubrication ⢠Conveyor belt repair ⢠Visual inspections ⢠Electrical and instrumentation adjustments.
Provisions must be made for overhead cranes to remove and replace crusher wear parts. Supports must be provided for gyratory and conveyor main shafts and laydown space for the cone crusher bowls is essential. Some operators carry a complete spare screen and change out for major screen maintenance. Trolleys, jib cranes and pull points should be designed to facilitate equipment maintenance. Oil and lubrication systems should be centralized and designed for easy automatic changes, with provisions for well-ventilated centralized lubrication rooms where possible. (e.g., a line of fine cone crushers should have a central oil receiving area, with piping to and from each crusher lube package for quick and easy oil changes.)
Conveyor head chutes should be designed for easy access (not just through an inspection door, but through a man door in the chute). Conveyor belt change areas should be provided. Maintenance personnel should have easy visual and rapid access to screen decks for panel replacement. Designers should work with the screen manufacturers to ensure that covers provide good access for working on screens. Screening facilities must meet rigid dust emission requirements, but many off-the-shelf screen dust covers have not kept pace with these requirements. It may be necessary to custom-design covers that minimize emissions and provide easy access to the screen.
Climatic Conditions
Building for cold-weather operations is very challenging, as is designing a plant in a desert environment. This is particularly true when year-round operation is required. Seasonal variations can change ore moisture content, so the crushing plant must be adaptable to changes in the material flow characteristics. Higher moisture requires greater angles of withdrawal, and stoneboxes must be designed to avoid plugging. The crushing plant equipment itself must be adjustable to climatic changes; for example, screen decks must be designed to maintain production, possibly by using wire mesh during the wet season and plastic during the dry. (Vary screen deck types dependent on seasons and material characteristics to achieve maximum passing through deck openings.
Climate also dictates the type of plant enclosures required as shown in Figures 1 and 2. Many crushers in milder weather climates or desert areas are installed with an open face and have no enclosures at all.
Our supplies a full range of cost effective, heavy duty, fit for purpose, crushing solutions including jaw crushers, cone crushers, horizontal shaft impact (HSI) crushers and vertical shaft impact (VSI) crushers. Our crushing solutions are ideal for primary, secondary and tertiary applications in quarrying, mining, recycling, infrastructure and construction.

In mining operations, the layout of crushing plants and ancillary equipment and structures is a crucial factor in meeting production requirements while keeping capital and operational costs to a minimum. This paper addresses the critical design parameters as well as the consideration of ore characteristics, geographical location, climatic conditions, expected operational life, expansion potential, safety, environment, and operability and maintainability.
Crushing Plant INTRODUCTION
The fundamental goal for the design of a crushing plant is an installation that meets the required production requirements, operates at competitive cost, complies with todays tough environmental regulations, and can be built at a reasonable price despite the rising costs of equipment, energy and construction labor. The following industry trends must be taken into account:
Equipment suppliers are offering ever-larger primary crushers, with 1,800 mm (72 in) gyratories expected soon, as well as secondary and tertiary machines of up to 3,000 mm (120 in).
⢠Rising energy costs are causing owners to increase the integration of mine and mill design, so that they can identify ways of reducing overall electrical power consumption.
⢠Electronic control of crusher discharge opening and feed rate. With adjustment of a crushers discharge opening, as the production continues through an on-line coarse size analysis of the crushed product (digital image analyses). Dance, A. 2001)⢠More attention is being paid to the impact on crushing circuit design caused by variations in ore characteristics, size distribution, moisture content, ore grade and climatic conditions.
⢠Operators have always dreamed of reducing the need for crushing equipment; when SAG mills were first introduced, it was hoped that they would eliminate secondary and tertiary circuits. As it turned out, designers are now adding secondary or pebble crushers to SAG circuits, on both greenfield and retrofit projects, to increase feed rate to the SAG mill. In other words, crushing plants, from primary to quaternary circuits, are here to stay.
There are three main steps in designing a good crushing plant: process design, equipment selection, and layout. The first two are dictated by production requirements and design parameters, but the layout can reflect the input, preferences and operational experience of a number of parties.
These can include the owners engineering staff, safety personnel, operations and maintenance personnel, equipment manufacturers, and the engineering consultant. Ideally, the consultant combines his knowledge and experience with an understanding of all parties needs, to provide a balanced, workable, safe and economic plant design.
Capital Cost
Direct Costs. The largest primary gyratory crushers cost US $2 million or more, while overall crushing plant costs can be as high as $18 million. Its necessary therefore to estimate crusher installation costs based on equipment costs plus the following direct costs, including construction contractor indirects:
Indirect Costs. Indirect costs can fall within a range of 40 to 60% of the direct costs, and include:
⢠Construction indirects ⢠Startup and commissioning ⢠Construction equipment ⢠Freight ⢠Spare parts/first fill ⢠Taxes/duties
⢠Engineering, procurement and construction management (EPCM) ⢠Ownerâs costs (relocation, hiring and training personnel, permits, licensing fees, etc).
In addition to the above, a contingency to cover unforeseen costs will be in the range of 10 to 20% of the sum of the direct and indirect costs. The designer must be aware of the project-specific costs of all such elements, so that he can monitor costs and promote methods of reducing total installation costs. In some locations, for example, labor and material costs could make a gabion wall more expensive than a poured concrete wall, which has minimal structural backfill.
Ore Characteristics
Ore characteristics are a critical element in both crusher selection and plant design. Dry ores require greater provisions for dust suppression and collection, including dust enclosures around screens, sealing on conveyor skirts, and vacuum and wash-down systems. Wet, sticky ores can plug chutes, reduce surge capacity, and decrease the live storage capacity of bins and silos. To address this problem, chutes must be easily accessible for clean-up, and large feeder openings must be provided for bins, silos and tunnels. If it is practical to obtain representative ore samples, it is prudent to have testwork conducted to establish ore flow properties, which will influence design parameters.
At virtually all mines, ore characteristics change over time, and it can be costly to design in the optimal flexibility required to handle such changes. Some owners stipulate that initial capital investment be kept to a minimum, with design modifications paid for out of the operating budget. This is not always easy to achieve.
Safety and Environment
Safety must be designed into all mining facilities. North American mines must comply with local and national regulations such as OSHA, MSHA, the Mines Act and the WCB. The modern plant includes safety guards around all moving equipment, and emergency pull-cords on both sides of any conveyors with personnel access. The maintenance department and safety officer must keep these safeguards in working order. Ongoing safety training of plant personnel is imperative, and is considered to be one of the most vital and monitored feature of most mining operations.
Dust emissions must comply with the latest regulations for the jurisdiction. Designers must make provisions for the installation of dust abatement, suppression or collection equipment. Spillages from feeders, chutes and conveyors must be minimized. Spill collection can be designed in on feeder installations; chute designs can minimize spillage at receiving and discharge points; and conveyor belts can be widened to be more forgiving (e.g., skirting internal back-to-back width can be reduced to allow the belt more side travel.) Skirting should be extended a minimum of three belt widths past the load point. Rules for conveyor and load point design should be used for guidance only, with transfers custom-designed to suit a particular project. It goes without saying that clean plants have lower operating costs. Crushers, screens and dust-collection fans all contribute to high noise levels. Air-cooled lubrication systems are not only noisy, but often leak oil. Well-balanced, choke-fed crushers, dustenclosed screens and dust collector fans with silencers can keep noise levels under control. Recirculating water can be used to cool crusher lubrication systems.

Uzbekistan, officially the Republic of Uzbekistan, is a doubly landlocked country in Central Asia, formerly part of the Soviet union. It shares borders with Kazakhstan to the west and to the north, Kyrgyzstan and Tajikistan to the east, and Afghanistan and Turkmenistan to the south.
Uzbekistan is rich in natural resources, and its stronger in the five Central Asian CIS countries. Uzbekistans pillar industry of national economy is four gold : gold, wihte gold(cotton), black gold(oil), blue gold(gas). However, the economic structure is single and the processing industry is lagging behind. Agriculture, animal husbandry and mining is developed.
Uzbekistan is rich in mineral resources, the total value of mineral reserves reach 3.5 trillion dollars. There are nearly 100 species of proven minerals. The minerals are mainly natrual gas, coal, petroleum, nonferrous metals, gold, copper, lead, zinc, and rare metals, gold reserves etc. Among the minerals, gold reserves rank fourth in the world, annual production of 80 tons, ranking 2nd in the CIS. Copper and tungsten reserves rank in the forefront of the CIS countries. Oil, silver, and platinum, zinc, bauxite and other metal deposits are also very abundant.
Uranium mining accounted for 25% of the former Soviet Union. Coal reserves are about 2 billion tons. Natural gas resources are mainly distributed in the northeast Karakul basin edge and the Bukhara Deer inverstigation stage area, and the largest gas reserves of gaz is about 4193 cubic meters. Oil resources are more concentrated in the eastern Tianshan fold belt of the Fergana Basin, and the proven reserves are of 5.84 million tons.
The natural gas reserves are after Turkmenistan, ranking second in Central Asia, third in the CIS. Industry of Uzbekistan is important in Central Asia, and gas, machinery,nonferrous metals, ferrous metals, textile, and silk industries are more developed in Central Asia.
The main export materials from Uzbekistan are cotton, petroleum, natural gas, power, nonferrous metals and agricultural products, the imports are mainly machinery equipment, food, industrial raw materials.
As the report showing, Uzbekistanâs mining industry is important to the economy. The mining machineries are imported from East Asia, South Asia etc. Benco is a crusher and grinder manufacturer in Shanghai. The crushers include: jaw crusher , cone crusher, impact crusher, and vertical shaft crusher, sand making machine,etc. Grinders(pulverizers) include: ball mill, high pressure mill, trapezium mill, roller mill, Raymond mill etc. The crushers and mills are widely used all over the world.

Major rock types processed by the crushed stone industry include limestone, granite, dolomite, traprock, sandstone, quartz, and quartzite. Minor types include calcareous marl, marble, shell, and slate. Major mineral types processed by the pulverized minerals industry, a subset of the crushed stone processing industry, include calcium carbonate, talc, and barite. Industry cla ssifications vary considerably and, in many cases, do not reflect actual geological definitions.
Rock and crushed stone products generally are loosened by drilling and blasting and then are loaded by power shovel or front-end loader into large haul trucks that transport the material to the processing operations. Techniques used for extraction vary with the nature and location of the deposit. Processing operations may include crushing, screening, size classification, material handling and storage operations. All of these processes can be significant sources of PM and PM-10 emissions if uncontrolled.
Quarried stone normally is delivered to the processing plant by truck and is dumped into a bin. A feeder is used as illustrated in Figure 11.19.2-1. The feeder or screens separate large boulders from finer rocks that do not require primary crushing, thus reducing the load to the primary crusher. Jaw, impactor, or gyratory crushers are usually used for initial reduction. The crusher product, normally 7.5 to 30 centimeters (3 to 12 inches) in diameter, and the grizzly throughs (undersize material) are discharged onto a belt conveyor and usually are conveyed to a surge pile for temporary storage or are sold as coarse aggregates.
The stone from the surge pile is conveyed to a vibrating inclined screen called the scalping screen. This unit separates oversized rock from the smaller stone. The undersized material from the scalping screen is considered to be a product stream and is transported to a storage pile and sold as base material. The stone that is too large to pass through the top deck of the scalping screen is processed in the secondary crusher. Cone crushers are commonly used for secondary crushing (although impact crushers are sometimes used), whic h typically reduces material to about 2.5 to 10 centimeters (1 to 4 inches). The material (throughs) from the second level of the screen bypasses the secondary crusher because it is sufficiently small for the last crushing step. The output from the secondary crusher and the throughs from the secondary screen are transported by conveyor to the tertiary circuit, which includes a sizing screen and a tertiary crusher.
Tertiary crushing is usually performed using cone crushers or other types of impactor crushers. Oversize material from the top deck of the sizing screen is fed to the tertiary crusher. The tertiary crusher output, which is typically about 0.50 to 2.5 centimeters (3/16th to 1 inch), is returned to the sizing screen. Various product streams with different size gradations are separated in the screening operation. The products are conveyed or trucked directly to finished product bins, to open area stock piles, or to other processing systems such as washing, air separators, and screens and classifiers (for the production of manufactured sand).
Crushed stone plant
Some stone crushing plants produce manufactured sand. This is a small-sized rock product with a maximum size of 0.50 centimeters (3/16 th inch). Crushed stone from the tertiary sizing screen is sized in a vibrating inclined screen (fines screen) with relatively small mesh sizes.
Oversized material is processed in a cone crusher or a hammermill (fines crusher) adjusted to produce small diameter material. The output is returned to the fines screen for resizing. In certain cases, stone washing is required to meet particulate end product specifications or demands.

Congo MANUFACTURING
The Congos manufacturing sector plays a small role in the economy, consisting of around 100 factories in Brazzaville and Pointe Noire, mostly engaged in the processing of agricultural and forest products. There are a number of companies engaged in manufacturing import-substitution products such as footwear, soft drinks, chemicals, cement, and metal-working products. The less significant sectors of the manufacturing industry produce textiles, footwear, cement, and soap.
Congo OIL.
Oil is Congos main export and the major support for a faltering economy. In 1998, the Congo exported more than 257,000 barrels of oil daily, and petroleum comprises some 50 percent of exports. In sub-Saharan Africa, the Congo is the fourth-largest oil producer, and has an estimated 1.5 billion barrels in reserve.
In 1994, the Congo took steps to deregulate the oil industry by offering production-sharing agreements with major foreign oil companies. This initiative is intended to regularize the flow of income to the government. Despite these steps, declining oil prices in 1998 badly hurt the Congos economy. The French oil company Elf-Aquitaine, which accounts for 70 percent of Congos annual oil production, is the major producer, along with the Italian oil firm Agip, and Chevron and Exxon from the United States. Rising worldwide oil prices in 2001, together with new discoveries and production, are expected to increase export revenues in the coming years.
The Congo has the third-largest natural gas reserves in sub-Saharan Africa, estimated at over 3 trillion cubic feet. As of 2001, however, there was no development of a natural gas industry. The Congo has substantial reserves of copper, lead, zinc, gold, and platinum, but these metals are mined in small quantities.

As any aggregate producer knows, it is a rare occurrence for Mother Earth to provide natural material deposit characteristics that perfectly meet 100% of the end product mix and processing requirements driven by the business needs as it related to mix designs or product sales of products like rooming granules. There is frequently an abundance of ½ x 3/16 washed or clean sized aggregate, commonly considered a surplus material. In many regions, some producers are managing inventories consisting of several hundred thousand tons of such material.
This type of surplus material is generally in low demand and low in value and due to the continued increase in fracture requirements of fine materials and/or demand for specialty products, these same producers are often in need of higher volumes of more valuable manufactured sand.
Producers are typically faced with limited choices with regard to surplus materials. One choice is to simply stack the material and hope to sell or consume it at minimal to not profits, possibly at a loss. Inventorying such large quantities of this material can be a financial burden as well as an additional expense associated with storage and stockpile maintenance. In some cases, surplus materials also create issues when there is not adequate storage space at the facility.
An alternative is to process the material into a manufactured material is in greater demand and of greater value. The desired manufactured product to be created out of the surplus gravels is typically a manufactured sand (100% passing 3/16″ with no more than 2% passing #200), and at times producers may also desire production of 3/8 x 3/16 chip.
Sand cone crusher
However, the types of crushers deemed suitable for sizing this manufactured material were typically roll crushers or vertical shaft impactors (VSIs). Roll crushers are sometimes prohibitive in terms of indirect labor costs associated with maintenance, are limited by a relatively small reduction ratio and unable to meet todayâs particle shape requirements. Due to roll crusher constraints the market turned to the VSI which addresses reduction ratio and particle shape requirements and is known to products a sound fine aggregate. Most producers still employ the VSI today but sometimes at a higher than desired operating cost. Gravel and glacial rock are inherently hard and abrasive, and the design of these machines in an abrasive environment equates to a high consumption of white iron and higher indirect labor costs. Some producers run the VIS only as needed and decommission it when not required. This causes a trickle down to the consumer through higher premiums of mix.
Various VSI manufactures have resolved wear issues to some degree with advancements in accelerator and shelf designs that are intended to reduce the wear by impacting material as opposed to the white iron. However, the trade off for rock-on-rock impact crushing is generally reduced efficiency. This can lead to a higher level of near size material being reintroduced into the VSI, leading also to ultra-fine material (-200M).
Before the emergence of high performance remote adjust cone crusher, producers also attempted to grind out the fines with a cone. Prior to the mid 1990âs there were few models specifically designed to crush sand, but these machines were thought of as lacking adequate capacity and application flexibility. Many other operators attempted to produce sand with conventional cones and simply followed the same guidelines as they would in conventional applications. This was achieved by operating the cone at a discharge setting very close to the desired top size of the end product and new super-fine liners were developed.
Many quickly found that when operating at a 3/8″ or smaller discharge setting with a long parallel zone in the liners, the machine quickly consumed all available power and the result was often overload events. When a machine was able to perform, the quantity of #200′s was too great and created new challenges at the wash plant or with quality control on mix designs. When these issues were coupled with relatively low production in the more expensive cone crusher, the economics were simply not in favor of the cont.
Cone Crusher New Paradigms
The emergence of high performance remote adjust cone crushers has brought a fresh start to the process and over the past decade more producers have been decommissioning the VSI in favor of the cone crusher for turning their surplus materials into top grade manufactured finer materials. The longer stroke, steeper geometry and opportunity for increased operating speeds that cone crushers provide is a more favorable recipe for efficiency and economical fine attrition crushing. These types of circuits are emerging in stationary, portable and even track installations. The process consists of a loading device such as a surge hopper or belt feeder, cone crusher, an inclined or horizontal vibrating screen configured specifically for efficient fine opening screening, and the transfer and stacking conveyors. Most producers employ a level sensor in the crusher to regulate the feed rate from the surge to the crusher to prevent overload.
The cone crusher is typically operated at a fairly coarse discharge setting and kept full of material (choke fed) so as to allow the inter-particle attrition to perform the majority of the crushing. This process allows the flats and corners to be crushed under compression, thereby increasing the cubicity. The manganese chamber is typically fairly coarse relative to the feed size and discharge setting (a medium chamber is often used). The RPM will typically be in a higher range to help maintain inertia that offsets amperage consumption while also helping retain material in the chamber longer to maximize efficiency.
A typical screen setup might include a 3/8″ top deck opening and a 3/16 on the bottom deck, with a load-relieving center deck. Care should be taken as to not blind the 3/16 bottom deck opening. A higher screen frequency, coupled with moderate to minimal stroke, tends to yield the highest performance. This combination will help to increase material travel speed so that material band on the deck is as thin as possible, enabling fines to sift through the oversize material and get discharged to the pay pile. The use of high frequency screens has proven effective for making splits less than 4M (3/16″).
Once the system has been designed and the equipment has been selected and positioned, the actual procedure itself is actually very simple, as listed below and illustrated as:
1. The crusher discharge setting must be calibrated and then the initial CSS set at about 0.50″
2. Start the screen and all transfer and stacking conveyors â DO NOT START THE SURGE FEEDER YET.
3. Start the under-crusher discharge conveyor;
4. Begin feeding the system and build up a load in the surge;
5. When the surge hopper is full, turn on the surge belt feeding the cone. The purpose is to immediately choke the cone. (Note, the cone will not remain choked very long and if a diesel engine is being used it is normal to struggle. The cone may also float.)
6. Open the cones discharge setting until any float stops. Depending on material conditions and moisture this could be as coarse as .80″ to .90″.
7. Dial in the feed rate and the discharge setting to maximize sand output and keep the cone choke fed. If feeding the plant manually vs. an automation system, this may require 10 to 15 minutes to achieve a steady balance. At this point a discharge setting of around 0.6″ to 0.7″ is typical.
8. A circuit that is fed dry material can provide as much as 25% higher capacity as compared to material possessing 10% moisture, thus provisions designed to protect stockpiles such as sloped pads and/or an enclosed storage facility will likely prove to be a good long-term capital investment. This process can provide the desired particle shape while simultaneously producing significantly fewer undesirable fines compared to the VSI.
Where a VSI often requires replacing the consumable parts on a daily basis, a set of cone liners in the same material can generally last several hundred hours between intervals. In most cases this dramatically reduces indirect, non value-added labor and maintenance costs, reduces the need to manage replacement parts inventory, and will yield a lower operating cost with a machine that is well-suited for a variety of other applications.
We are continuing to explore ways to recycle concrete, however, and to incorporate it into our products and promote its use in sustainable construction where feasible and allowed by law. As part of the WBCSD Cement Sustainability Initiative, the cement industry has been looking to recycling concrete as a component of sustainable business practice.
In July 2009, the CSI published Recycling Concrete in an effort to promote concrete recycling and support the long-term zero landfill goal for concrete. The findings underline the many challenges of the practice, including cost and the fact that the cement and demolition industries are in different sectors.
The benefits of recycling concrete include reduced waste, landfill, or dumping and associated site degradation; substitution for virgin resources; reduced transportation and disposal costs; and the creation of new employment opportunities in the recycling industry that would not otherwise exist.
