High pressure roller mill – Making.com - Vekamaf
The high-pressure roller mill from Hosokawa Alpine is also called roller crusher or roller press. In comparison to compaction processes, it uses lower press forces between the rollers because no new adhesive forces need to be created. With high-pressure roller mills products are produced with a precipitous granule distribution.
Bandmill blade guide pressure - WOODWEB
Roller guides are used with down pressure to make sure they are controlling the blade. The crown of the wheel on a saw with roller guides may not be doing the job. Guides with flat plates are dependent on the crown of the wheels more so. If you have problems cutting straight I would suspect sharpness, cutting speed and set (in that order).

Drive systems for high pressure grinding rolls RollXtend
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 fixed roller delivers more torque than the movable roller. For values of Klf > 1 the movable roller delivers more torque than the fixed roller. Klf can be varied in fine steps.
Ball Mills - an overview | ScienceDirect Topics
They have lower specific energy consumption than ball mills and the separator, as in raw mills, is integral with the mill body. In the Loesche mill, Fig. 2.23, 16 two pairs of rollers are used. In each pair the first, smaller diameter, roller stabilises the bed prior to grinding which takes place under the larger roller.
Shear stresses and material slip in high pressure roller mills
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.
High pressure roller press as pre-grinding to ball mill ...
High pressure roller press can be introduced as a pre-grinding step for the ball mill, in order to decrease specific power consumption in finish grinding and/or to increase the output of finish mill.

Troubleshooting roll defects - Valmet
Non-uniform nip pressure: See above. Crushed roll. Sometimes called a "baggy sock roll" and is the result of stacking rolls on end in an excessively high pile which in turn causes the lower rolls to fail in an axial direction. Excessive axial pressure: Stack rolls to a more conservative height. Winding too soft: Wind rolls harder. Dished roll
