High Pressure Grinding Mill Principle: In the mainframe of the mill, there are strong springs with pressure as high as kg equipped on the roller suspender. When High Pressure Grinding Mill (Raymond Mill) works, the roller rotates around the principal axis, and clings to ring under the effect of the strong spring and eccentricity.

Scrubber nozzles are typically highpressure (5001,000 psi), lowflow rate nozzles that are targeted after the grinding zone to remove chips from the wheel structure. Chips can also stick to the grinding wheel, in some cases. This can happen in more aggressive grinding or when grinding certain metals that tend to stick to the grinding wheel.
