Raymond Fine Grinding Roller Mill

The Raymond fine grinding roller mill is an air-swept vertical pendulum mill with integral classification. A vertical shaft rotates an assembly of grinding journals /rolls inside the grinding zone. As the unit turns, centrifugal force drives the rolls against the grinding ring. Feed material enters the mill from the top of the grinding zone
