Introduction

Impact crusher, which can also be called impact breaker, counterattack impact crusher, impact pulverizer or impact crusher, is a machine used for crushing medium-hard and crisp materials relying on the impact energy. Impact breaker can process all kinds of materials whose side length is less than 300mm and compression strength lower than 260MPa and has such features as big crushing ratio, high crushing ratio, cubic shape of the product and selective crushing. In addition, it has better adaptability when crushing materials with big compression strength such as granite, limestone and river cobble.

Features

Impact Crusher

1. The gap between the impact plate and the plate hammer is conveniently adjusted, which can effectively control the discharging granularity and the particle shape is good.

2. The ores are crushed along the joint surface, so the electricity consumption is low and the working efficiency is high.

3. Keyless connection makes the check and maintenance is convenient and the machine economical and reliable.

4. Impactor crusher has comprehensive crushing functions, high production capacity, small abrasion of the spare parts and high comprehensive benefits.

5. The plate hammer is made of high chromium with big shock resistance and wear resistance.

6. Impact pulverizer has simple structure, small size, light weight, high production capacity and low production cost; in addition, it has big feeding mouth, high crushing chamber and high hardness of the adaptive materials.

7. The crushing ratio is big and can reach 40, which simplifies the crushing process and turns the three-stage crushing into two-stage or one-stage crushing and reduces the equipment cost of the ore beneficiation plant.

8. It has selective crushing function, and the crushed products is even in granularity and in the shape of cube, so that they are widely used in the construction of bridge, highway, wharf and airport.

Principle

Impact breaker makes use of the plate hammer on the rotor that is rotating with high speed to crush the materials that are sent into the crushing chamber by the high-speed impact. The crushed materials will be thrown with high speed to the impact board on the other end of the crushing chamber along the tangential direction and be crushed again, and then the materials will bounce back from the impact board to the plate hammer to repeat the process. In the roundtrip, the materials will also hit with each other. As the materials sustain the hit of the plate hammer, impact of the impact board and the crush of the materials, the materials will constantly produce cracks, become loose and crushed. When the granularity of the materials is smaller than the gap between the impact board and the plate hammer, they will be discharged out.
