Descripción del producto

1. Roller crusher is a kind of crushing machine consisting of roller, supporting bearing, compression and 
2. adjusting device, and actuating device, etc. It is suitable for coarse grinding and intermediate crushing in cement plant, 
3. chemical industry, electric power station, mining, metallurgical industry, production of building materials and
4.  fireproofing materials and other industries.The double rollercrusher can crush materials whose compression
5. strength is not more than **0MPa.The discharging size is adjustable,and largesize materials can be crushed into 
6. different sizes.In coal industry, double roller crusher can directly crush the raw coal through deironization and 
7. decontamination, and there is no need to remove coal gangue. Crushed materials are of small and even size. Thus, 
8. the process of coal dressing is simplified and the production cost is reduced.
9. Roll crusher Working principle: 
10. 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.
