The working part of the hammer crusher is many hammers hinged on the turntable according to a certain law, when the turntable tells the rotation, the hammer due to centrifugal force and rotation force, hit the material loaded into the machine, so that it is broken, at the same time, the hit stones hit each other and with the machine lining plate, the castor bar collides with each other, but also promotes the material to break.

Common hammer crushers have two kinds of single rotor and double rotor, according to the arrangement of hammers on the turntable, as well as single row hammers and multi-row hammers, etc., the rotor steering has reversible and irreversible two types. In addition, there are some simple hammer crushers, such as cross hammer crusher, chain ring coal crusher, etc. Among them, the most widely used is the single-rotor multi-row hammer crusher.
Hammer crusher is generally suitable for brittle materials with water content less than 12% and compressive strength less than 120MPA, such as limestone, oil shale, slag, coal blocks, etc.
2. The advantages of hammer crusher are:
1. Simple structure, compact size, small self-weight, small power consumption per unit product
2. High productivity, large crushing ratio, small and uniform particle size of the product, cubic shape, less excessive crushing phenomenon.
3. Continuous and reliable work, convenient maintenance and repair, easy inspection and replacement of vulnerable parts.
3. Wearing parts of hammer crusher:
The parts in the hammer crusher that are in direct contact with the material, such as hammers, liners, castors, etc., wear out quickly and need to be replaced frequently.
