Impact crusher is also called sand maker. The vertical impact crusher consists of seven parts: feed, distributor, vortex crushing chamber, impeller experience, spindle assembly, base transmission device and motor. As far as its working principle is concerned, the impact crusher is simply the principle of stone to stone. Let the stones collide with the stones thrown by the impeller in the process of natural falling, so as to achieve the purpose of crushing. However, when the stones thrown out at an accelerated speed collide with the stones falling naturally, eddy currents are formed, which are broken again in the return process, so the abrasion of the impact plate of the machine is very small during operation.

The stone directly falls into the high-speed rotating turntable from the upper part of the machine, and under the action of high-speed centrifugal force, it collides with another part of the target stone distributed around the turntable in an umbrella shape at high speed and is crushed at high density. After the stones collide with each other, they will form a vortex motion between the turntable and the shell, resulting in repeated collision, friction and rolling, and then discharged through the lower part. A closed loop is formed for many times, which is controlled by screening equipment to achieve the required particle size. 1. This machine is a new type of medium and fine crushing equipment developed in 1990s, and it is also a widely used model in the world to replace cone crusher and roller crusher.

2. The structure is novel and unique, and the operation is balanced.

3. Low energy consumption, high yield and large crushing ratio.

4. The equipment is small in size, simple to operate and convenient to install and maintain.

5. It has molding function, and the product is cubic with high packing density.

6, in the production process, stone can form a protective bottom, the fuselage wear-resistant, durable.

7. A few wearing parts are made of extremely hard and wear-resistant materials, which are small in size and light in weight and easy to replace accessories.
