Primary impact crusher a primary impact crusher is generally used for crushing materials of grain size and for recycling concrete and quarried stone.Most impact crushers are secondary crushers, but there are primary impact crushers as well.With higher reduction ratio than the jaw crushers and with dependable crushing performance, the primary impact crusher is capable to crush even the hardest materials.This crusher is composed of a rigid and durable rotor, over-sized bearings, a hydraulic mono-block feed plate, a large feed opening, and hydraulic cylinders that provide continual crushing force.
The screening and crushing equipment in zenith has high output and utilizes the crushing way with shearing pressure that's more powerful than impact pressure, that is more appropriate for bauxite crushing.With this, the screening and crushing devices are used more frequently than before.Based on the different customer's interest in capacity, the gear could be coupled with impact crusher, hammer crusher or roll crusher, through crushing, sieving and certifying to obtain the product that you would like.
Limestone medium crushing equipment recommended: impact crusher & cone crusher.The impact crusher can granite, limestone, concrete, and the like coarse materials with a side length of less than 500 mm and a compressive strength of less than 350 mpa.impact crusher vs cone crusher impact crusher has a lower price, uniform discharge, less needle-like crushed product.The cone crusher is slightly more expensive, but the wearing parts have a long life.In the long run, the cone crusher is more durable.impact crusher vs hammer crusher the impact crusher has a larger crushing ratio and can more fully utilize the high-speed impact energy of the entire rotor.The impact crusher is easy to wear, which makes it limited in the application of hard material crushing.
Make up of screening equipment, medium crushing plant (common use small jaw crusher impact crusher and cone crusher), sand making plant ( sand making machine or vertical shaft impact crusher), check screening plant and adjustable sand making.Its main duty is crushing the semi-finished to four aggregates: 0~4.75mm4.75~19mm19~37.5mm and 37.5~75mm.Sand making plant primary missing is crushing the materials that less than 37.5mm to fine aggregate less than 4.75mm, in order to supplement the natural sand insufficiency, and to adjust the natural sand fineness modulus.
B.Impact crusher is a two-stage crushing equipment, which is the equipment for crushing the discharged material of jaw crusher again.It is not suitable for crushing high hardness stone such as granite and basalt, and has good crushing effect for brittle and soft stone;.
However, impact crusher now there are still some problems.Which is more prominent is the board hammer wear faster (especially when crushing hard materials), and a wide particle size distribution (for some industrial sectors, the products do not want more fine particles or unnecessary).However, the current real obstacles impact crusher there are barriers to further promote the use, design and manufacturing sector to design and test the impact crusher is also a lack of systematic and complete understanding, in particular, specific design, take little of the crushing effect and equipment the relationship between structure and properties, the lack of theoretical basis, some places are also due to improper use.
Selection from a variety of coarse and medium-fine crushing models of ci5x series impact crushers can be made so that the selected model is absolutely ideal for the coarse or medium-fine crushing of medium-hard or soft materials with huge or medium throughput.

Generally speaking, the major differences between impact crushers, both vertical shaft (vsi) and horizontal shaft (hsi), and cone crushers is the type of crushing force.Impact crushers crush by material impacting another object.Cone crushers use compression crushing where the material is crushed by being squeezed or compressed between two crushing surfaces.Selection of the type of crusher and the crushing process for any application depends on material hardness, and density of the material, feed size, desired product size, and capacity needs; as well as initial costs for each crusher and the cost to maintain each style of crusher.Basic construction and working principle:horizontal shaft impactors consist of a hopper, two or three aprons, a rotor, and blow bars or hammers.Essentially, large products are fed into the hopper where they come into contact with hammers or blow bars to a spinning rotor which crushes the material into smaller pieces.As the larger material gets impacted by the hammers, it comes into contact with each apron rebounding it back to the rotating hammers for another round of impacting until it is discharged out of the hsi.Vertical shaft impactors consist of a feed hopper, a feed tube, a rotor, and either stationary anvils or rock shelves.Essentially, feed material drops through the feed tube into the rotor, which, through centrifugal force, throws the material against stationary anvils made up of composite metal alloys or rocks (through the installation of a rock shelf).When the rock impacts on the anvils or rock shelves, it shatters along natural stress lines, creating a uniform, cubical product.Cone crushers consist of a bowl liner, a mantle, both main shaft and frame, compression, and an eccentric inner and outer bearing.Essentially, material is reduced in size by squeezing the material until it breaks.Specifically, the material is compressed between a moving piece of steel, the mantle, and a stationary piece of steel, the bowl liner.The final products size is determined by the closed-side gap setting between the two crushing members at the bottom.As the cone eccentrically rotates, the material is crushed and works its way down through the crushing chamber, until it discharges at the bottom of the machine.Material composition for the crushing process:in order to understand cone and impact crushing processes, one must know the material that will be crushed, which will determine the optimal crusher for your business needs.When considering the material to be crushed, you must look at abrasiveness, hardness, density, amount of fines, and the finished particle shape you desire.Impact crushers are used to crush softer, less dense and abrasive material such as limestone.Because of its consistent striking process, an impact crusher produces uniform cubical finished products, which are desirable for hot asphalt producers.Depending on the application, impact crushers can have higher wear costs, higher maintenance, and produce more fines.Impact crushers may be used as a primary, secondary, or tertiary crusher depending on the producers final-product-size needs.These crushers are available in stationary, track and mobile designs.Another industry usage is slag, specifically blast furnace slag, which is less abrasive than steel furnace slag and can be broken down if processed through an impact crusher.Cone crushers are primarily used to crush harder, more abrasive and dense material, such as granite, which is used in construction, chemical, metallurgical and silicate industries.Cone crushers can be used in the primary, secondary, and tertiary position.These crushers are available in stationary, track and mobile designs.Cone crushers are also used in the steel furnace slag industry, which is a much more abrasive slag than blast furnace.Overall costs:impact crushers, initially, are less expensive than cone crushers.Although cone crushers are more expensive up front, they will require far less maintenance than impact crushers.The majority of maintenance costs on an impact crusher comes from wear on the blow bars and aprons which if used to crush highly abrasive material, may surpass the initial cost of the cone crusher.As stated earlier, producers must understand their industry needs and the materials they will mine in order to choose the optimal crusher.View telsmith cone crushersview telsmith impact crushers.
So, the impact crusher can be used as the final crushing equipment to produce concrete aggregate for the antiskid pavement of high-grade highway.
Just as cone crusher widely used in the crushing process, impact crushers serve for secondary reducing.Both of them reduce mineral with soft, medium and high hardness such as limestone, clinker, furnace clinker, hard coke, coal, etc.And widely applied into mining, construction, cement and metallurgy industries.But why impact rocks are better than cone crushers when it comes to demands of perfect product shape? here are some reasons.
