Hammer crusher is used for crushing medium hard materials with weak abrasiveness, and the compression strength of the materials to be crushed should not exceed 100MPa, and the water content should be lower than 15%. The materials of hammer crusher are coal, salt, chalk, gypsum, tile and limestone and also fiber structure and broken wood and paper with strong elasticity and tenacity.
Working Principles of hammer Crusher:
The electromotor drives the rotor to rotate with high speed in the crushing chamber. The materials are fed into the machine from the upper feeding mouth and are crushed under the hitting, impacting, cutting and grinding of the hammer which is moving with high speed. On the bottom of the rotor, there is sieve plate and the crushed materials that is smaller than the screen size are discharged from the sieve plate, and the coarse particles bigger than the screen size are retained on the sieve plate to be hit and ground again by the hammer and finally be discharged from the machine from the sieve plate.
To crush medium-hard or brittle materials with hardness not more than 300Mpa and 15% moisture, such as coal, cement, gypsum, alumen, brick, tile, limestone, etc.
