Jaw crusher is mainly used for coarse crushing and medium crushing of hard and medium hard materials. When working, the moving jaw plate of the main eccentric shaft moves to and fro periodically with respect to the fixed jaw plate, sometimes approaching, sometimes leaving. When the moving jaw is close to the fixed plate, the material is broken between the two jaw plates. When leaving, the broken material will be discharged automatically due to gravity. Because of its simple structure, reliable work, easy maintenance and low production cost, it is widely used in coal, building materials and other industries. But because the friction between the material department and the jaw plate is more intense, the jaw plate is worn fast.

Roller crusher is a kind of old equipment. When working, the two relatively rotating rollers pull the materials on the two rollers into the gap of the two rollers under the action of friction force and break them. The distance between the two rollers determines the product size. Its structure is simple, maintenance is easy, adjustment is convenient, and the product is too crushed less. So it is widely used in the industrial furnace forming machine at present The disadvantages are low comminution ratio and productivity, large equipment area and uneven roller wear.

The hammer crusher uses the fast rotating hammer head to crush the material. It is widely used in medium and fine crushing of brittle and medium hardness materials. Because of its high crushing ratio (10? 50), low energy consumption per unit output, convenient management, compact body, movable operation and high production capacity, it has also been widely used in the coal industry: the small model with a productivity of 2? 3 tons / hour is suitable for individual users of single machine supporting production.
