The development of modern science and technology is changing with each passing day. With the help of high-tech technology, many shredder equipment with different working principles and different purposes have been developed in the market. Among the many crushers, there are mechanical crushers, jet crushers, grinders, cryogenic crushers, etc. Among them, mechanical crushers have been used in the mining industry for a long time and have a wide range of uses. For customers who invest in the sand and gravel production industry, they will pay more attention to mechanical crushers. This article will give you a detailed introduction today.

What are the mechanical crushers?

Mechanical crusher is a device that crushes materials mainly by mechanical means. According to different working principles, mechanical crushers can often be divided into extrusion crushers, percussion crushers, impact crushers, and so on.

1. Extrusion crusher: Two mechanical parts are squeezed to the middle to produce a large force, thereby forcing the stone in the middle of the parts to crush to achieve the purpose of crushing. Mechanical crushers that use this working principle include jaw crushers, cone crushers, and roller crushers.

2. Percussion crusher: A device that crushes materials (including hammering, collision, friction, etc.) through the relative movement of a high-speed rotating movable hammer and a fixed ring. Crushers that use the percussion crushing principle include impact crushers, hammer crushers, two-stage crushers, vertical crushers, and single-stage crushers.

Generally, the size of the stone aggregate processed by the impact crusher is better than that of the extrusion crusher, but the output and crushing efficiency of the extrusion crusher are generally higher.

3. Impact crusher: The working principle is very similar to that of the impact crusher, but there are also differences. Under this working principle, the stone material will gain higher kinetic energy after being hit by a high-speed rotating component, thrown into the air in the opposite direction, and collide with the material coming in. The material coming in after the impact gains energy to change the falling trajectory and hits at high speed Crush the cavity wall and smash. Impact mills have both organic and rock-to-stone beating. The complex working principle allows the crusher that uses this working principle to have a better crushing and sand-making effect, and has lower component wear.
