High pressure roller mill

The high-pressure roller mill from Hosokawa Alpine is also called roller crusher or roller press. In comparison to compaction processes, it uses lower press forces between the rollers because no new adhesive forces need to be created. With high-pressure roller mills products are produced with a precipitous granule distribution. Because only the

Rolling (metalworking)

To minimize the roll diameter a four-high or cluster mill is used. A small roll diameter is advantageous because less roll is in contact with the material, which results in a lower force and power requirement. The problem with a small roll is a reduction of stiffness, which is overcome using backup rolls. These backup rolls are larger and

Cement mill

High-pressure roll presses. These consist of a pair of rollers set 8–30 mm apart and counter-rotating with surface speed around 0.9 - 1.8 m.s −1. The bearings of the rollers are designed to deliver a pressure of 50 MPa or more. The bed of material drawn between the rollers emerges as a slab-like agglomeration of highly fractured particles.
