Guikuang aiming at the character of coal ash cement and improved the configuration of grinding mill, which will largely increase the efficiency. At the same time, the new equipment has better environmental performance and is suitable for modern coal ash cement production.

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

However, coal ash can be applied as the mixed material of cement 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 coal ash, and will rise for 20-30% if added coal ash and slag. It will also increase corrosion stability.

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

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