Grinding Glass Microsphere for Grinding Mill Product Description

Grinding Glass Microsphere for Grinding Mill Grinding Glass Microsphere

1. To select glass beads in types, sizes and quantity in accordance with viscosity, rigidity and dispersal of the grinded materials. 

2. To clean glass beads and mill's inside before the grinding processed. 

3. To input the grinded materials firstly and a curtain amount of glass beads later. To add continuously glass beads till 70%~80% of the mill is full. 

4. To forbid to keep glass beads funning with little grinded material for a long time, as the glass beads inside the mill are easily broken at high speed operation. 

5. To add new glass beads to ensure the quality and efficiency of grinded materials.
