Material crushed in an impact crusher is an example of dynamic impact. When the material is crushed in an impact crusher, the freely falling material first breaks due to dynamic impact by a moving hammer and then the force of impact accelerates movement of the reduced particles toward breaker blocks and/or other hammers for further size

Hammer crusher is used to diminish particle barite size from 0100 mm down to about 0–5 mm impact, using 24 hammers, each of which weighs about 5.300 kg. These hammers are distributed on 4 shafts, set around a rotor, rotating at a high speed of 1400 rpm inside a crushing chamber. The feeding rate is about18 tons/h.

The hammer impact crusher frame body is located on the upper part of the bottom groove and installs a crushing hammer shaft in the middle of the frame body. The mechanism is that the hammer shaft is lifted to a certain height through the transmission device which increases the gravitational potential energy.

1. The displacement sensor is damaged. The displacement sensor of the three-roll crusher is broken and detached due to its external metal sleeve, thereby damaging the displacement probe inside the sensor, resulting in inaccurate gap measurement and malfunction of the equipment.. The main reason for the damage caused by inspection and analysis is that the vibration is large and the wear is fast.
