A first survey of grinding with high-compression roller mills

Apr 01, 1988  A first survey of grinding with high-compression roller mills. Int. J. Miner. Process., 22: 401-412. The special feature of high-compression roller mills (HC-roller 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.
