impact crushers

The Impact Crusher (impactor crusher), also called counterattack impact crusher, crushes stones under the impact force produced by the impellers, so it is also called impact rotary crusher.Impact Crusher is mainly used in secondary crushing, and can crush material its crushing compression strength not more than 320 MPa. It is suitable to produce aggregate for highway, hydroelectric and building material industry, etc. Additionally, our impact crushers have obtained ISO 9001:2000.

Impact Crusher Working principle

1. Many cavity to crush, suitable for crushing hard rock.

2. Use the hydraulic to open, easy to maintain and change wear-parts.

3. New anti-abrasive material makes longer service life of impact bar, impact plate and line.

4. Reasonable design of leveling plate making charge finer and cubic without interior cracks.

5. Low and big feed opening makes the production line easy to arrange and increase the size of feeding material.

7.Lining design standardization, interchangeability of spare parts, reduce the user types and inventory, and replaced more easily.

8.Rotor welding processing, assembly is required to do static, dynamic balance test, allowing the rotor to run more smoothly, the use of a longer time.
 
9.Back frame and the grinding frame adjustment has the advantages of simple structure, easy operation, not easy to damage, and convenient repair, low cost.

6.Unique plate hammer locking device, fastening torque greater, more secure, more simple, convenient replacement of the plate hammer, fast.

7.The unique design of the hydraulic device, which can facilitate the user to easily open rack, replacement parts, but also on the back frame adjustment of the discharge hole.
 
8.Simple locking device, the back broken shell and shell two is tightly locked together. The device has the advantages of simple operation, convenient, save the locking time.

9.Product versatility, two cavity crushing equipment without change in other parts of the foundation, increase the grinding frame, can be turned into a three cavity crushing equipment, reduce user two investment.
 
10.Heavy rotor, finite element stress analysis, optimization design, structure more reasonable, moment of inertia is greater, more than broken, broken ability, stronger abrasion resistance.

11.The spindle adopts the high quality forgings machining, while the shaft without keys design, using the advanced international expansion sets tight connecting way, can make the equipment run more reliable, more convenient maintenance.
 

Working Principle of Impact Crusher
 
When the materials enter the field of the hammer, it is impacted by the hammers, thrown onto the impact plate, and crushed. The stuff springs from the impact plate, is impacted by the hammers again, and thrown onto impact plate. This process will last until the stuff meets the requirement and falls from the machine. Adjusting the distance between impact frame and rotor frame can change the shape and size of the output. When some foreign stuff enters the machine, the impact frame will fallback, the stuff falls from the machine. This device can prevent machine from damages.
