Raymond Mill
3R / 4R / 5R / 6R Series Raymond Mill
A vertical pendulum roller mill. The rollers are pressed outward against the grinding ring by centrifugal force, and the material is ground by rolling contact. Product fineness is adjustable from 80 to 400 mesh, with some materials reaching 500 mesh. It handles non-metallic minerals and chemical raw materials below Mohs 7 and 6% moisture, and is one of the most widely used milling machines in the industry.
- Vertical layout with a small footprint; a complete system from lump feed to finished powder
- Very uniform product with a high screening pass rate — hard to match with other mill types
- Sealed gearbox and belt drive for smooth, reliable transmission
Key features
- Vertical layout with a small footprint; a complete system from lump feed to finished powder
- Very uniform product with a high screening pass rate — hard to match with other mill types
- Sealed gearbox and belt drive for smooth, reliable transmission
