The grinding mill has the following characteristics:

1, grinding unique way: the grinding rolls are hung in grinding ring parallels , milling roller and grinding ring have 6-8mm clearance, grinding roll and grinding ring, do not contact directly . The grinding ring driven by material rotates the grinding roll, and the grinding roll by two spring high-pressure pre-tightening force makes the material crushing and grinding.

2, because the grinding roll and grinding ring do not directly contact , the content of iron in material is low, and not to drop white degrees.

3, stronger grinding force: grinding force of grinding roll generates from both root of preloaded force high-pressure spring (about 4000Kg) . The force is three times of 4R3216 Raymond mill’ s grinding force.

4. Bigger grinding surface.

5. Finished granularity: the finished granularity reaches 1500 mesh.

6. High output, low energy consumption: the output of 1250 mesh calcium carbonate is as much as 1.2 tons/hours.

Main technical parameters: (Three roll)
