Hengyang High Pressure Roller mill is principally a vertical mounted double-roll mill, equipped with hydraulic pistons on one side, pressing against the floating roll - the other roll being fixed in the frame.

The main components of the machine are of course the rolls, the bearings, frame, pressure beams, hydraulic system, drive system, lubrication and cooling systems, and the feed chute. Feed is introduced into the gap between the rolls in a choke-feed manner, and is comminuted by a mechanism of interparticle breakage.

Feed coarser than the gap is broken by feeding hopper. The degree of comminution achieved is determined by the pressure applied to the rolls. Pressures in the gap may range from 50 to 320 Mpa. Forces vary with the diameter of the rolls from about 750-20,000 kN (75 - 2000 to). For orientation purposes, the compressive strengths of most hard ores lie in the range of 180-240 Mpa. The force required for the breakage of particles < 60 mm is usually < 100 kN. Roll diameters vary from 0.5 m to 2.8 m, and roll widths vary from 0.2 m to 1.8 m.
