What is the role of the impact crusher's impact plate?

The impact crusher is named according to its working principle, that is, the use of impact crushing principle to break materials. It is a more refined crushing equipment than the jaw crusher, mainly used for fine crushing operations in stone production lines, and crushed in cooperation with the jaw crusher.
The effect of the anti-impact plate is to withstand the impact of the material hit by the plate hammer, so that the material is broken by the impact, the impact of the broken material rebounds to the impact area, and the impact is broken again to get the required product particle size.

There are many forms of crusher anti-impact plate, mainly zigzag and arc two. The zigzag counterattack surface can make the material on each point of the counterattack plate impact in an approximate vertical direction, so as to obtain excellent crushing effect. The curved counterattack surface can make the block bounce off the counterattack plate, and then form a violent impact crushing zone at the center of the circle, thereby increasing the free impact crushing effect of the material.
The anti-impact plate frame is generally welded with steel plates. The counterattack surface of the crusher is equipped with a wear-resistant liner, but it can also be composed of a counterattack roll or a grate. The counter surface with grate groove has less fine particle content, which can improve the production capacity of the equipment and save energy consumption. However, there are also some defects such as complex structure, difficult replacement of counterattack surface after wear and fast wear.
The rotor of the impact crusher is made of integral cast steel, the structure is strong and durable, easy to install the plate hammer, and the mass is large, which can meet the crushing requirements. The rotors of small and light impact crushers can also be welded with steel plates.
