Optimized crusher selection for the cement industry

Optimized crusher selection for the cement industry

>stone crusher used in cement industry

The characteristics of raw materials required for the cement production differ at a wide range. The limestone deposits used today as base material, show very different properties regarding hardness, abrasiveness and stickiness. To optimize the crushing process as well as the investment and operating costs, different types of >crushers are available. To make a proper selection, several important points should be considered in advance.

/>

Stone crusher

The very first step should always be an analysis of the quarry, and especially the characteristics of the raw material. Of prime importance is the hardness of the material to be crushed. To describe this property the compressive strength, the Los Angeles Index or the Mohs Hardness should be determined and a point load test should be carried out.

The abrasiveness of the material has to be described by its Silica and free quartz content, as well as the abrasion index. Just as important is an expression of the stickiness. For this reason the moisture, the clay content and, in very difficult applications, the handling coefficient (shear test) has to be ascertained. Based on this data an overview of the selection criteria allows a pre-choice of the required crusher.

Primary crushing of limestone for the cement production requires high crushing ratios to reduce the material in a single step, down to the required grain size (approx. 0 – 25/80mm) for the raw mills. It should always be the aim to have as few crushing steps as possible, in order to minimize the investment and maintenance costs and time. According to the above overview, one step crushing can be achieved by operating Hammer crushers or Impact crushers. These crusher types are fast running machines providing high kinetic energy, resulting in strong impact forces and high crushing ratios. The allowable maximum compressive strength of 150 Mpa is normally sufficient for most of the limestone applications.

The silica content is an important issue to be considered before using Hammer or Impact crushers. Due to the high speed of the rotors, the crushing tools (hammers or impact bars) are vulnerable to wear. The limit for these machines is 8-12% silica content. Before making a final decision, the abrasiveness of the raw material has to be analyzed very carefully to avoid suffering from high maintenance costs.

If the silica content is above mentioned values, a crushing system with a small speed difference between the material to be crushed and the crushing tools should be used. As final material characteristics, the moisture content has to be taken into account. While the >hammer crusher can take on a moisture content of up to 20%.

This special feature allows charging limestone and sticky materials like e.g. clay at the same time, to obtain a pre-homogenization within the crusher. Wherever the silica or the moisture content is too high for hammer or impact crushers, a two-step crushing system is a better solution for reducing the material to the requested grain size for the raw mills.

Available for these two-step systems are Double Roll crushers, RollSizers, >jaw crushers and Gyratory/Cone crushers, which are all able to operate in abrasive material. But while the crushing ratio of these crushers is approx. the same (1:5 to 1:6), their ability to crush hard and/or wet material differs.

Jaw and Gyratory/Cone crushers reduce the material by high pressure, which makes them perfect for processing hard materials with a compressive strength of up to 400 Mpa. Because of the relatively low compressive strength of limestone (< 150 Mpa), these crushers are mainly used for highly abrasive limestone. On the other hand these machines are sensitive to high moisture contents, which have to be considered very carefully.

Double Roll crushers and RollSizers combine pressure and impact, as well as shear and tensile forces for crushing. They are limited regarding hardness of the material (max. 175 Mpa), but they are able to crush very sticky and abrasive materials.

The previously given explanations show, that for every kind of limestone there is a suitable crusher combination to produce the required grain size distribution. But not only for limestone, also for the necessary additives (like e.g. clay, lime, puzzolan, sandstone, >iron ore, schist etc.) with their different material characteristics, the proper crushing method can be realized.

Impact crushers

With the introduction of vertical roller mills, which accept a raw material size of up to 80mm, the Impact crusher became of prime importance for the cement industry. Modern Impact crushers are equipped with heavy duty rotors in common rail design. Specially designed cast discs are combined on one main shaft, concentrating the main weight at the circumference of the rotor. The result is a high moment of inertia and kinetic energy, which allows one-step crushing of the raw material down to the required product size.

State-of-the-art Impact crushers are equipped with hydraulically supported impact walls and grinding path, allowing a calibration of the crushing gap and the product size according to the requirements. Therefore one crusher can be sufficient to produce limestone with a grain size of 0/80mm for the raw mills and a grain size of 0/35 mm as additive for the cement mills.

To meet the problem of having uncrushable material like e.g. tramp iron in the feed material, each Impact crusher should be equipped with an effective overload protection. ThyssenKrupp Fördertechnik achieves this by a patented combination of the grinding path and the lower impact wall.

As soon as an overload occurs at the lower impact wall, the supporting cylinder is released and the gap between impact wall, grinding path and rotor is being widened. This avoids any damages to the grinding path by opening the gap before the tramp iron passes through. After discharging the uncrushable material to the discharge >conveyor, the hydraulic cylinders move the impact wall and the grinding path back to the former position. Maintenance-friendly details like interchangeable wear plates, quick release bolts for very fast opening of the housing, hydraulically fixed blow bars, blow bar lifting and rotor positioning devices are also standard items of recent impact crushers.

Double Shaft Hammer crushers

/>

Hammer crusher

The main crushing process of a Double Shaft Hammer crusher is performed by rotating hammers between the rotor and on the anvil. It is important to understand, that the material is not ‘ground’ on the grate baskets. The grate baskets calibrate the material grain size by different openings, in order to produce raw material either for ball mills (0/25 mm) or vertical mills (0/80 mm).

Double Shaft Hammer crushers are used in the cement industry to solve crushing problems in difficult materials like wet limestone combined with clay. This capability to operate under such severe conditions without clogging problems is achieved by the self-cleaning effect of this machine, which results from the fact that the material is mainly in contact with rotating elements. Only the grate basket to calibrate the final grain size is fixed but also cleaned by the rotating hammers. Of course the entire crushing chamber geometry, the design of the anvil and the grate baskets have to be optimized and adapted to avoid clogging problems. The advantage regarding the non-clogging effect of the Double Shaft Hammer crusher is illustrated in.

Impact crushers and Single Shaft Hammer crushers crush the material by impact of the blow bars or hammers and by throwing the material against fixed side walls, which are not cleaned. The Double Shaft Hammer crusher works like a Double Roll crusher, where the material is only in contact with moving, self-cleaning crushing tools.

The ability to crush sticky materials allows the simultaneous feeding of several materials by means of two or three apron feeders, causing a pre-homogenization within the crusher.

Double Roll crusher and RollSizer

Despite of their low crushing ratio both Double Roll crusher and RollSizer are used in the Cement and lime Industry. Unlike the impact and hammer crushers with their high rotor speed, the roll crushers operate at low speed, producing a minimum of fines content. This fact makes these machines especially suitable for the lime production, where a maximum of stones for the kiln is required. But also under difficult conditions like extremely sticky (clay) or abrasive (clinker) material this type of system is the perfect solution, thanks to low operating speeds and non-clogging effect.

Because limestone is mainly not very abrasive or extremely sticky it can be crushed in one step and the Double Roll crusher and the RollSizer are rarely installed as primary limestone crusher. But especially regarding additive processing they are important, in order to achieve an economic crushing solution.

>cone crusher

Jaw crushers and Gyratory/Cone crushers are the perfect choice for hard rock applications. They can be used for very abrasive but dry and non-sticky materials with a compressive strength of up to 400 Mpa. Their crushing ratio is relatively low, compared to Impact and Hammer crushers, thus for primary limestone applications a two step crushing system is necessary.

Because of that, they are rarely used for the production of main material for raw mills. Just like Roll crushers these systems can minimize the fines and maximize the stone content in the crushed product to be used in the lime production. Additives like e.g. iron ore can also be processed perfectly with Jaw and Gyratory crushers.

Although the materials used for the cement production are quite different regarding hardness, abrasiveness and stickiness, there is a wide range of crushers and crushing systems available, meeting all requirements. They allow the optimization of each crushing process and thus a minimization of investment and operating costs.

The Key Styles & Functions of Crushing Equipment

So far, there are many styles of crushers. According to the principle acting force of crushing materials, they are roughly divided into compressive crusher, effects crusher, shear-type crusher, rotary crusher, and cone crusher.

Shear-type Crusher

It includes dental-type sizing crusher, double pin roll classifier, WMG roll crusher of Germany, and the double pin roll crusher produces by KRUPP company of Germany. Mainly through effect of cut, stretch, bend, pierce, snap, separation, materials can be crushed. Filly utilize the of rock, coal and coke, etc: pressive strength＞tensile strength＞slip resistance. Owing to advanced crushing principle, this crusher obviously characteristics energy-saving.

Main Attributes of Shear-type Sizing Crusher are:

①Double effects of crushing and classification

The new tooth-type sizing crusher: crushing tooth is spirally fixed up on the pin roll, and two rolls are in relative movement like rotary grizzly screen. For materials smaller than size of product, they will be screened out; for lump materials, they will be crushed. Therefore, it can avoid materials in the crusher mingling with crushing defects. This crusher capabilities double effects of crushing and classification, it can finish operation of crushing and screening alone in a certain range. Screening plants don’t need allocating, which can simplifier system and save invest.

②Strictly guarantee size of products

This machine adopts fixed centre distance, forcedly crush the materials. The structure and size of pin roll is designed on basis of requirements of product size, which can strictly control the bulk of passed products. It is the gatekeeper of products’ final size. It features with qualified and epigranular products, low production of slack coal, energy-saving, low productive maintenance fee.

③ Extremely low over-grinding efficiency

Adopting the shear principle, the particles smaller than required size can directly pass through, and for the materials bigger, crushing process is needed. It can avoid materials entering into the crusher mixed with crushed defects. So the over-grinding efficiency is extremely low. For hard materials like coal, coke, over-grinding efficiency is generally below 5%.

④ Simple structure, matched with advanced overload protective device

The long toothed gearing of traditional crusher and concession system are abandoned so as to reduce middle consumption and fault point. The whole machine is easy to operate, and the two rollers are fully symmetrical which possess good interchangeability. In addition to the overcurrent protective system and beltwork protection, special mechanical protector is equipped to ensure the reliable operation of the complete machines. Also, once the rotors are locked, the machine will autostop, and raise the alarm so as to protect the machine and the whole system.

⑤ Adjustable centre distance

Rigid adjustability is initiated at home on the premise that product’s size is ensured. With this function, centre distance can be easily, quickly adjusted according to requirements of product size. In production, if we choose the unreasonable crushing plants, not only unnecessary waste of energy will be caused, but also disposal cost of tailings will be raised for the increase of slack coal content, or coal marketing will be influenced because of unqualified size of products, which will directly damage the economic benefit of enterprise.

Compressive Crusher

Compressive crushers mainly include jaw crusher, roller crusher of plain or trough tooth surface, etc. The operating principle is: materials are crushed by the compression, separation and bend action between fixed dental plate and movable dental plate. Materials are crushed together in crushing cavity, which will easily cause crashing and produce large sheet products. So this crusher can’t ensure the size of products and consume much energy. It is mainly used to crush hard materials, and is widely applied to fields of metal mine and crushing stones.

Impact-type Crusher

Impact-type crushers mainly include affect crusher, ring-hammer-type crusher, etc. In the crusher, with the run-up hammer blowing, materials fly to impact plate as high speed, effect, and reverse affect. Meanwhile, materials influence and crush with other in cavity, part of the materials get cut by the action of strike blade and impact plate. With bad controllability, this method will produce massive coal ash; it’s even worse for coal of low hardness and high brittleness. Also, it is not suitable to the rough and secondary crushing process. However, it is suitable to be adopted in crashing process.

SBM Angola granite plant 700 TPH and Developing Sand from Rocks VSI in UAE

Project title: Angola granite plant 700 TPH

■ Time starting manufacturing: March, 2010

■ Material sourcing: quarry

■ Materials sort: granite

■ Max. diameter: 750mm

■ Moh’s hardness:

■ Designing creation: 700TPH

■ Working hrs: 8 hrs for each day

■ Processing movement and equipments:

Primary crushing, secondary crushing, tertiary crushing, screening.

The introduction of Deep Rotor VSI cone crusher has solved two typical challenges in quarry area. A shortage of organic sand direct the quarry proprietor to look for a machine can develop very good sand. Also, the building market place need for far better aggregate form.

Solution:
After consultation with Zenith Mineral’s engineer, they would like to add a B Series Deep Rotor VSI-7611 within the existing plant. This machine will carry the materials in the current plant of (20-40mm) and lessen it to 0-5mm; 5-10mm; 10-20mm. The B-VSI is created to produce incredibly great particle shape and a substantial planning of fines. Just after commissioning, the capacity of as much as 150TPH quickly, which specifically satisfy the quarry owner’s preliminary strategy.

Case Study
A quarry operator inside the UAE required to increase their crushing and screening plant in order to cope with an raise in chip and sand desire from the market place. Materials is granite. They already have one particular primary plus a secondary crusher. Materials arrives out from the impact over 20mm. the secondary crusher was being operated at extremely tight options, but nevertheless was not able to cope with all the fines specifications. Final items they necessary is 0-5mm; 5-10mm; 10-20mm (total 3 solutions).

Advantage of B-Deep Rotor VSI Crusher: 

Rotor is the heart of VSI, the success of Zenith B-VSI attributes to the application of new technology for its deep rotor.

The deep rotor is about 50% better than that of normal rotor, which means there is a higher space between distributor and feed eye ring, also as between the upper and decrease wearing plates. Capability in this way improves at least 30% then the traditional VSI crusher.

Saudi Arabia Influence crushersbm horIzontal Impact crusher available for sale

Purpose designed to procedure development supplies on web page, the QI240 continues to be created with mobility, productivity, transportability, nominal environmental influence and consumer friendliness at its core. Saudi Arabia QI240 is tangible representation of SBM’s commitment to servicing the growing market for the recycling of building materials and the production of high quality aggregates from materials previously seen as waste.

The QI240 utilises market leading SBM impactor technology enabling the growth of a fully mobile, Saudi Arabia compact impact crusher developed to either work in a primary or secondary capacity either independently or in conjunction with other members of the SBM product line, in order to produce the highest quality supplies. Although developed for the recycling of development supplies, the state of the art SBM impactor design enables the QI240 to be the perfect impact crusher for the smaller quarry. Here its compact design is perfect where space and machine manoeuvrability are at a premium, but superb product shape and high levels of production are required.

Saudi Arabia Impactor, Saudi Arabia Influence Crusher QI240

The QI240 possesses recent developments that will ensure it becomes the impact crusher of choice throughout the building industry:

•The machine is fitted with a pre-screen to ensure maximum scalping capability in order to prevent any undersize material passing through the impactor, thereby maximising throughput and reducing wear costs. This also allows a specified sized product for being produced from the natural fines conveyor.

•With a choice of grizzly, punch plate or heavy duty top deck mesh, the QI240 possesses the flexibility to suit any application.

•The QI240 is fitted with an underpan feeder which drastically reduces any spillage issues generally associated with impact crushers. The underpan feeder eliminates the need for skirt rubbers that are normally situated in the severe impact zone of a feed boot.

•The underpan feeder also protects the main product conveyor from high velocity material from the rotor. This material is contained on the wear resistant under-pan feeder liners and gently delivered onto the conveyor belt.

•The SBM Pri-Sec impactor is the most flexible impactor currently available on the market created to meet end product specifications.

•The 2 hydraulically adjustable apron curtains can be positioned to facilitate the machine’s operation as a Primary impactor but can also be repositioned to operate as a Secondary impactor to produce much smaller end products.

•The above combined with the variable engine speed gives a tip speed range of 30 m/s to 37 m/s resulting in a wide variety of product specifications being achievable.

Precast Concrete

In 1950, the completion with the Walnut Lane Memorial Bridge in Philadelphia, Pennsylvania, signaled the starting in the precast concrete market in North The us. Virtually unfamiliar in the Usa till the construction of this prestressed concrete bridge, today, precast concrete structures, which includes bridges, are commonplace inside the Usa.

Precast concrete is extensively applied in low- and mid-rise apartment buildings, motels, motels, and nursing properties. The concrete provides remarkable fireplace resistance and seem control for that person models and minimizes fireplace insurance coverage charges.

Precast concrete is also a well-known materials for setting up office structures. The partitions of the constructing is usually manufactured even though the on-site foundations are being built, delivering substantial time savings and leading to early occupancy.

The speed and ease with which precast structures might be constructed has aided make precast a popular making material for parking structures. Precast concrete makes it possible for efficient, cost-effective development in all climate circumstances and gives the long very clear spans and open up spaces necessary in parking structures. For stadiums and arenas, seating models and concrete steps may be mass created according to requirements, providing quickly set up and lengthy lasting assistance. Additionally, pedestrian ramps, concession stands, and dressing area places can all be framed and built with precast concrete.

The smooth surfaces made with precast concrete as well as the capability of precast, prestressed concrete to span long distances tends to make precast suitable for use in production and storage structures. Extra applications for precast concrete include piles and deck for railroad and freeway bridges, railway crossties, burial vaults, academic institutions, industrial properties including buying malls, and public properties including hospitals, libraries, and airport terminals.

A advantage of precast concrete is the fact that the product is developed in ideal production conditions. Despite the fact that some items are solid outdoors, especially in temperate climates, many precast plants operate indoors where the environment may be completely controlled.

Standard or Special

There are two forms of precast solutions. Common products including beams, decks, and railroad ties are formed in 1 way and applied more than and more than once more. The other sort of product is really a specialty item, designed specially for the building, bridge, or construction exactly where it is going to be utilised. Most precast firms have their very own carpentry retailers exactly where experienced employees make forms for that several specialty precast products out there. Architectural concrete is frequently solid specifically for every single new venture.

The forms, no matter whether common or specialty, are well oiled. Concrete is placed within the forms and allowed to remedy. Soon after curing, the product is carefully lifted from your type and taken to a property for further curing just before it can be shipped towards the venture web site. The form is then cautiously cleaned and prepared for the subsequent batch of concrete. Lots of precasters can flip over their forms every single one or two days.

Beneficiation Operations

Beneficiation of ores and minerals is outlined in forty CFR 261.four as such as the following activities: crushing; grinding; washing; filtration; sorting; sizing; gravity focus; flotation; ion trade; solvent extraction; electro successful; precipitation; amalgamation; roasting; autoclaving; chlorination; and heap, dump, tank, and in situ leaching. The beneficiation technique(s) chosen varies with mining operations and is determined by ore characteristics and economic concerns.

Conventional Milling/Flotation

This section describes the typical phases inside the conventional milling/flotation of sulfide ores. A flow sheet illustrating this process is presented in Figure 1-4. Crushing and Grinding the very first stage in beneficiation is comminution. Normally, this can be achieved by sequential size reduction operations—commonly referred to as crushing and grinding. Crushing may possibly be performed in two or three stages. Main crushing techniques consist of crushers, feeders, dust manage systems, and conveyors utilised to move ore to coarse ore storage. Major crushing is typically accomplished by a jaw or gyratory crusher, because these units can handle bigger rocks.

Figure 1-5a exhibits a typical jaw-type crusher. Cone crushers, revealed in Figure 1-5b, work very best at large, high-capacity functions due to the fact they're able to deal with larger tonnages of material. The feed to main crushing is commonly run-of-mine ore, which can be lowered from substantial pieces (two to four ft in dimension) to smaller parts (8 to ten inches in dimension). Main crushing methods are ordinarily located close to or in the pit at surface area mines or below the surface area in underground mines. Crushed ore is then transferred to secondary crushers, typically situated close to the next stage in beneficiation. The ore might be temporarily saved in piles in the web site.

Secondary and tertiary crushing commonly is performed in surface facilities in cone crushers, despite the fact that roll crushing or hammer mills are at times employed. In these reduction phases, ore must be reduced to about 0.75 inches just before being transported (ordinarily on conveyer belts) to a grinding mill (U.S. Congress, Workplace of Technologies Evaluation 1988; Taggart 1945; Wills 1981).

Size separators (including grizzlies and screens) control the size with the feed material amongst the crushing and grinding stages. Grizzlies are typically used for incredibly coarse material. Screens mechanically individual ore dimensions working with a slotted or mesh floor that functions like a “go/no go” gauge. Vibrating and shaker screens are essentially the most generally employed forms of separators. There are various different kinds of vibrating screens, created to manage material among twenty five centimeters (cm) and five mm. Just after the last screening, h2o is added to the crushed ore to type slurry.

Grinding will be the final stage in comminution. In this operation, ore particles are lowered and labeled (normally within a hydro cyclone) right into a uniformly sorted materials amongst 20 and two hundred mesh. Most copper amenities utilize a mixture of rod and ball mills to grind sulfide ore (Figures 1-6a and b). Rod mills use cost-free steel rods inside the rotating drum to grind the ore. A ball mill works by tumbling the ore against no cost metal balls and also the lining from the mill. Rod and ball mills are created with replaceable liners composed of high-strength chrome molybdenum metal bolted onto the mill shell. The grinding face with the liner is ribbed to promote mixing. The liners call for extensive upkeep and should be replaced on a regular basis. To replace the liner, the mill must be taken from production. A shutdown of a mill demands further milling capability to avoid general mill shutdowns for the duration of maintenance (U.S. Congress, Workplace of Technology Assessment 1988; Taggart 1945; Wills 1981). In a few cases, ore and water are fed into an autogenous mill (where the grinding media would be the difficult ores by themselves), or possibly a semiautogenous mill (where the grinding media are the ore supplemented by big metal balls).

Each unit within the collection generates successively smaller material. Ordinarily, crushed ore and drinking water enter the rod mill. Once the material is decreased to a specific particle dimension, it becomes suspended inside the slurry (due to its size and distinct gravity and also the movement in the mill). The fine material then floats out inside the overflow in the mill. At this point, the ore slurry is labeled based on particle size in a hydro cyclone or comparable device. Oversize materials passes towards the ball mill for extra grinding. Undersize material moves to the next phase of beneficiation.

After grinding, ore is pumped into a classifier developed to independent fine-grained materials from coarse-grained material necessitating further grinding. This strategy is employed to control each below and over milling or grinding. Classification is depending on distinctions within the size, shape, density, and settling price of particles inside a liquid medium. Different sorts of hydraulic classifiers are utilized. These generally fall into two groups: horizontal and vertical present classifiers. Mechanical classifiers are horizontal current classifiers, which are no more in broad use. The hydro cyclone is the regular technologies for vertical classifiers in use right now.
