Two roll hammer crusher is suitable for hard material as shale, coal gangue and construction waste, large volume ,high capacity, stable movement and extensive use is outstanding characteristics of this crusher, hammer head use high grade manganese steel material which ensure long lifetime. How does two roll hammer crusher work? As a professional crusher manufacture, Zhengzhou Hongrun Industry Co., Ltd will explain it to you.
1. Two roll hammer crusher have a theoretical maximum reduction ratio of 4:1. If a 2 inch particle is fed to the roll crusher the absolute smallest size one could expect from the two roll hammer crusher is 1/2 inch. Roll crushers will only crush material down to a minimum particle size of about 10 Mesh (2 mm). A crusher uses compression, with two rolls rotating about a shaft, towards the gap between the rolls. The gap between the rolls is set to the size of product desired, with the realization that the largest feed particle can only be 4 times the gap dimension.
2. The particles are drawn into the gap between the rolls by their rotating motion and a friction angle formed between the rolls and the particle, called the nip angle. The two rolls force the particle between their rotating surface into the ever smaller gap area, and it fractures from the compressive forces presented by the rotating rolls.
3. The fixed part of roller and movable roller are driven by the motor via reducer and v-belt, the raw materials fall into the part between the two rollers from inlet of the machine. The two rollers rotates inward simultaneously. The materials are extruded, crushed and grounds, then the end products come out from the bottom of this two roll hammer crusher.
