Common types of crushers include hammer crushers, impact crushers, cone crushers, gear crushers and drum crushers.

1. Hammer crusher

A hammer crusher is a machine that uses impact force to crush materials. It is mainly used for crushing harder materials, such as limestone, gypsum, coal, etc. The working principle of a hammer crusher is to use high speed, repeated impact and shearing of the hammer head on the material.

2. Impact crusher

An impact crusher is a machine with a high-speed rotating rotor, suitable for crushing materials of medium hardness, such as limestone, gypsum, etc. Impact crushers mainly rely on tangential impact force to crush materials.

3. Cone crusher

Cone crushers can be divided into coarse crushing, medium crushing and fine crushing types according to the different particle sizes of the materials. Cone crushers can be used in mineral processing, construction, cement and chemical industries, mainly using the pendulum motion of the crushing cone and the crushing of materials.

4. Gear crusher

Gear crushers are widely used in metallurgy, construction, chemical industry, electric power, transportation and other fields, mainly crushing materials into fine particles. Its mechanical structure is complex, consisting of a transmission system, rotor, panel, feeding device, etc., and the material is crushed by high-speed rotating gears.

5. Drum crusher

Drum crusher is a commonly used smaller crusher, suitable for shorter materials such as bricks, stones, etc. The drum crusher mainly crushes materials through the drum.

In short, different types of crushers are used for material crushing in different fields according to the hardness, viscosity and composition of the material. In the process of selecting a crusher, it is necessary to comprehensively consider a variety of factors according to the actual situation.
