Product Description

The impact crusher can handle materials with side length of less than 100-500mm, and has the advantages of high crushing ratio and cubic particles after crushing. Widely used in building materials, ore crushing, railways, highways, energy, transportation, energy, cement, mining, chemical and other industries. The discharge particle size can be adjusted, and the crushing specifications are diversified.

Product Advantage

1. The clearance between the counterattack plate and the plate hammer can be easily adjusted, the discharge particle size can be effectively controlled, and the particle shape is good;

2. The ore is broken along the joint surface, so it has less power consumption and high efficiency;

3. Keyless connection, convenient maintenance, economic and reliable;

4. Full crushing function, high productivity, small wear of parts and high comprehensive benefits;

5. High chromium plate hammer, impact resistance, wear resistance and large impact force;

6. The utility model has the advantages of simple structure, small volume, light weight, large production capacity and low production cost. Large feed inlet, high crushing chamber and high material hardness;

7. The crushing ratio is large, up to 40, so the crushing process can be simplified, the three-stage crushing can be changed into two-stage or one-stage crushing, and the equipment cost of the concentrator can be reduced

Working Principle

Impact crusher is a kind of crushing machine that uses impact energy to crush materials. When the machine is working, driven by the motor, the rotor rotates at a high speed. When the materials enter the plate hammer action area, they collide with the plate hammer on the rotor, and then are thrown to the impact device for crushing again, and then bounce back from the impact lining plate to the plate hammer action area for crushing again. This process is repeated. The materials enter the first, second and third impact chambers from large to small for repeated crushing, Until the material is crushed to the required particle size, it is discharged from the discharge port. The stones directly fall into the high-speed rotary table from the upper part of the machine; Under the action of high-speed centrifugal force, high-speed collision and high-density crushing will occur with the flying stones shunted around the rotary table in an umbrella form with another part. After the stones hit each other, eddy motion will be formed between the rotary table and the casing, resulting in multiple mutual hitting and crushing.
