Dolomite Mill

Dolomite, with hardness of 3.5-4 and specific gravity of 2.85-2.9, is widely distributed in nature. Dolomite is a relatively pure dolomite with a calcite content of less than 5%.

Dolomite Grinding Processing

1. Crushing stage: The bulk material is crushed to feed fineness (15mm-50mm) of the mill.
2. Grinding stage: Small pieces satisfying the grinding conditions are grinded into powder in the grinding chamber.
3. Classification stage: The material after grinding is classified by the separator.
4. Pulverizing stage: Fine powder enters the pulverizing system. The finished powder is sent to the warehouse, and then packed.
