WEBApr 1, 1988 · Abstract. 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. The milling force must be adjusted to a level so that the particle bed is loaded by a compressive ...
