The so-called crusher can crush some substances. According to the use and performance requirements in different fields, we may use different crushers. There are four common crushers: jaw crusher, cone crusher, roller crusher and impact crusher.
1. Jaw crusher (tiger mouth). The crushing action is to periodically press the movable jaw plate to the fixed jaw plate to crush the ore block sandwiched therein.
2. Cone crusher. The ore block is located between the inner and outer cones, the outer cone is fixed, and the inner cone swings eccentrically to crush or break the ore block sandwiched therein.
In the gap between two opposite rotating round rollers, the ore block is mainly subject to continuous crushing, but it also has grinding and stripping, and the toothed roller surface also has splitting effect. Belt conveyor,
4. Impact crusher. The ore block is crushed by the impact of fast rotating moving parts. Belonging to this category can be divided into: hammer crusher; Cage crusher; Counterattack crusher.
