Principle of operation:
This equipment adopts two motors, which take two rollers to rotate reversely by the decelerator. When the materials drop on the rollers through the feeding hole, under the friction of the rollers, they are dragged between the rollers, grinded by the roller's and crushing, the crushed materials are pushed rotatorily by the rollers.
Performance Features:
1. The structure is simple and compact, the noise is low, the efficiency is high.
2. The installation is flexible, basically needs no foundation.
3. The rollers' surface adopts anti-friction welding rod or exchangeable dental plate, the maintenance is simple.
4. Self-preservation ability is strong, high hardness materials (such as all sorts of metal block) won't break the equipment's parts when they enter the crushing cavity.
5. The discharging granularity is adjustable; the minimum can reach 2-10 mm.
