Description

technical field

[0001] The invention relates to a coal crushing device, in particular to a coal crushing device. Background technique

[0002] Crusher can be divided into medical crusher and mining crusher according to major categories;

[0003] Common crushing machines for heavy mining machinery include jaw crusher, impact crusher, vertical impact crusher, hydraulic cone crusher, ring hammer crusher, hammer crusher, roll crusher, compound crusher, Cone crushers, double-stage crushers, gyratory crushers, mobile crushers, etc., the working principles of different types of crushers are completely different;

[0004] Cone crusher is a mining machine used to crush ore. When working, the ore enters from the feed port of the cone crusher, and is crushed by impact and extrusion in the crushing cavity formed by the movable cone and the fixed cone. However, during the feeding process, the ore is broken to produce debris, which is easy to splash People, and the feeding direction is...
