## **Operating Mechanism**
### **Raymond® Ultrafine Mill**
- **Mill Type:** Vertical ring-roll, air-swept
- **Classification:** Integral turbine classifier
- **Grinding Zones:** Multiple concave zones with convex rolls
- **Operation:**
- **Feed Entry:** Top of grinding zones
- **Material Distribution:** Via centrifugal force on a spreading plate
- **Gas Stream Flow:** Upward through annular space around grinding zones
- **Material Separation:** Coarse particles separated by the turbine classifier and returned to grinding zone; acceptable material collected in a pulse jet dust collector (Available, Not Included)

### **Raymond® Roller Mill**
- **Feed Size:** Approximately ½ - 2 in / 10-50 mm
- **Product Particle Size:**
- Coarse: Approximately 10% R2000 micron, 90% minus 10 mesh
- Fine: As fine as 99.9% minus 325 mesh (0.001% R44 micron)
- **Material Processing:**
- **Hardness:** Most effective for materials 5 or less on the Mohs scale
- **Material Types:** Soft to medium-hard materials
