Why Choose Dry Process From Manufacturing Cement Methods

Dry process method means manufacturing raw materials into raw materials powder, whose water content is generally less than 1%. So, the dry process can `reduces heat loss needed by heating and autoclaving water. But the dry process has its own flaw that is the bad fluidity of materials grain in a kiln. It will cause an uneven mix.
