High Pressure Roller Mills are used in the cases of medium-fine crushing of hard materials such as ceramics, minerals from 5 up to 9 on the Moh's hardness scale, metals and metal alloys. High Pressure Roller Mills are used in continuous operation or in a closed circuit with screening machines or classifiers.
High pressure roller mill is widely used in the processing of 280 kinds of materials in mining, metallurgy, chemical industry, building materials and other industries. It is suitable for grinding non-flammable and explosive materials with Mohs
High Pressure Grinding KHD Humboldt Wedag Roller Presses. With our Roller Presses, the grinding pressure is transferred from the hydraulic system via the movable roll to the material bed and absorbed in a stable, closed machine frame. A key feature is the mounting of the rollers in oil-lubricated cylindrical roller bearings.
The structure of high pressure grinding roller mill The structure of high pressure grinding roller mill is various, but its principle is basically similar. The roller press is mainly composed of feeding device, material position control device, a pair of sticks, rotating device (motor, pulley, gear shaft), hydraulic system, and horizontal leakage prevention device.

Jan 22, 2002 The compaction of the particle bed in a high pressure roller mill causes pressure and shear forces on the rollers, which have been measured simultaneously with a sensor. As known, the pressure peak arises short above the gap neck, the shear is firstly orientated against and then in the rotation direction.

Evidence of roll to roll contact would be corrugations with tops
Köppern roller presses are centered around two counter-rotating rollers, supported in the frame by spherical, self-aligning roller bearings. In addition to radial loads, the bearings are able to accommodate axial loads acting in both directions, making them insensitive to shaft-skewing during operation.
The roller torques are managed by the load share factor (Klf). If Klf = 1, identical torque is delivered by both rollers. For values of Klf 1 the movable roller delivers more torque than the fixed roller

The HPGR (high pressure grinding rolls/rollers) is the core equipment of the high pressure grinding process. The machine reduces particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. This forces the rocks against each other and compresses the feed’s density to 80% of its solid 
1. Using a high-pressure roller mill in the process of the grinding system can increase the production efficiency of the entire system by 20% to 30%. At the same time, the total power consumption of the grinding system can be reduced by 25 to 50% compared with the conventional grinding method. 2.
The roller press is often used where energy-efficient grinding of large product quantities is required. The two rollers, rotating in opposite directions, exert very high pressure on the material, effectively crushing and weakening the particles (microscopic cracks), so that the subsequent fine grinding is easier.
