Cement mill - Wikipedia

These consist of a pair of rollers set 8–30 mm apart and counter-rotating with surface speed around 0.9 - 1.8 ms . 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. The energy efficiency of this process is comparatively high. Systems have been designed, including a de-agglomerator and separator, that will deliver material of ce
