Working principle:

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. Some major advantages

Usage and Application

 The series double-roller crusher can be applied in industrial sectors such as ore dressing, chemical industry, cement, refractory, abrasive and building materials to break to pieces ores and rocks of various high and medium rigidities, and particularly applied in the building material industry to produce pisolite and pea gravel, with better effect than ordinary crushers.
