Mica is the major solid waste of coal-fired power plants. Every year, the large sum or mica may cause environment pollution and resource waste.

However, mica can be applied as the mixed material of mica powder processing. The functions are improving capacity, energy saving, cost reducing, and can improve product performance.

The capacity of cement will rise for 10-15% if added with mica, and will rise for 20-30% if added mica and slag. It will also increase corrosion stability.

When producing mica powder, it can take the method of jointly grinding or separately grinding. The feeding mica fineness should be around 0.08mm (200 mesh), much smaller than other material.

Jointly grinding is to send the raw material, gypsum and mica into the mill to be ground together. The technology is simple and easy to operate. The mica will not only assist the grinding, but also help to clean the powder on the wall, which will increase capacity.
