  • Large capacity, uniform particle size

    VSI crusher incorporates three crushing types, the maximum throughput up to 520tph, and it can be operated 720 hours continuously.

  • Good final products shape

    The grain shape is good. And gradation and fineness modulus is adjustable, especially suits for artificial sand and stone shaping.

  • Low consumption and long service life

    Adopted best design and materials, leading to reduce friction of wear parts, directly reduces the costs and extends maintenance intervals and service life.

  • Easy to maintain and operate

    Equipped with hydraulic openings device, so it is convenient to overhaul the component and replace crushing chamber.

After materials are fed into the hopper, they are through a central feeding hole, thrown to the impellers, which are rotating at a high speed. Then the material are accelerated and thrown out of impeller area. There part of materials, first, impact on the other part of materials, which are falling down, and then, they together strike on the material layers or on impact blocks. Due to rebound, they will back to top of crushing cavity and again be shot back to strike on another part of materials which are shot from the impeller flow and form a continuous material curtain. The final products will be discharged from the discharge open at the bottom.

Ores and minerals, construction materials, timber, crushing and grinding food and rubbish has consumed nearly 12% of human energy. Especially with the increase of low grade ore mining and environmental protection to deal with the increase in recycling waste. Energy consumption has increased, is expected at the beginning of 21st century, used in the grinding process energy consumption could reach 15%. In factories, in the grinding process. Crushing and grinding equipment, maintenance costs and energy consumption per cent of the total cost of 50% per cent and, therefore, reduce these costs in the grinding process has become more urgent than ever before.
 
In most industrial plants and mines, eccentric cone crusher is used for crushing, Rod mill and the mill for grinding. Grinding Burns 80% power and grinding efficiency, not more than 1%. Reducing crushing product size to improve grinding efficiency. And can reduce energy costs and, in addition, crusher is lighter than the weight of the mill. Low prices and easy to operate.
 
Cone Crusher of kinematics concept in 1856 was made, the first cycle of cone crusher is in 1880 Ellis out ELMS (Allis-Chalmers) company. Cone Crusher applied in metallurgical, construction, road building, chemical and ceramic industry in the crushing of raw materials can be broken over medium and medium hardness of various ores and rocks. Cone Crusher crushing ratio, high efficiency, low energy consumption and uniform product size, suitable for medium crushing and fine crushing of various ores and rocks.
 
Cone Crusher wear process is abrasion and wear, it is causing material losses in industry one of the main reasons why. When two surfaces are in direct contact with, and when a surface harder than other surface, erosion has happened. Hard surface is pressed into the soft surface, pressure around into a severe plastic deformation. When there is a tangential movement, hard-surface planing and soft surfaces, soft debris scraped. Cone Crusher wear can be expressed through the open three-body abrasion. Under this condition, the particles can move each other and rotating or sliding along the ground surface of wear debris surface abrasion causes one or two medium clearance, close three-body abrasion can be eliminated by means of prevention is, open three-body abrasion characteristics is inherent to the process, it cannot be totally avoided. Open three-body abrasion can be of three types: planing, high stress and low stress.
 
In order to reduce the wear of cone Crusher liner, this product provides a cone crusher, it can effectively reduce wear lining, reduces the weight of the liner, improve efficiency, increase profitability.
 
This product solves the technical problem of technical solutions is to use a new crushing Chamber, new models of crushing cavity consists of two broken: single particle crushing and layer pieces.
 
Crushing process is divided into two phases: the first phase materials into the holding area, and ore in the upper ore evenly under the action of gravity and pressure to move to the next stage; the second phase to be completed in parallel with, material break up here is a complex process.
 
These crushers crushing cavity consists of two parts even if the material parallel to the preparation area and broken, parallel little broken area forming a cavity on the surface, these cavities along the tapered surfaces of circular distribution to form a honeycomb-like structure.
 
Small broken area forming a cavity above the total area shall be parallel with the area of 25-40%, cavity depth (h) parallel with lining thickness (a) 50-70%.
 
The beneficial effect of this product is effective to reduce the lining of wear and tear, reduces the weight of the liner, improve efficiency, increase profitability.
