Apr 01, 1988 · A first survey of grinding with highcompression roller mills. Int. J. Miner. Process., 22: 401412. The special feature of highcompression roller mills (HCroller mills) is that a bed of particles is compressed between two rollers to a high solid density more than 70% of volume. The size reduction occurs by interparticle crushing.
In ringroller mills rollers feed solid coarse particles against a stationary grinding ring. The particles are broken apart by the resulting compression forces. Equipment Design In a ringroller mill, the material to be milled is fed into the grinding section . The moving roller forces the coarse material against the stationary grinding ring.
The big grinding roller performs not only a purely rolling motion, but also a sliding motion because the roller axis and grinding table axis do not intersect in the plane of the table. The differential speeds due to this configuration are a desirable feature, producing an additional comminuting action by the shearing forces developed.
