1. Our rotary cement kilns are all made of thermal insulation material, which reduces the radiation heat loss and energy consumption during the burning process; 2. We use the compound fish scale to soft seal the front end and the back end of the rotary cement kiln. The air leakage coefficient can be thus controlled less than 10.

Raw Material Preparation

Raw Material Preparation

When rotary kilns were developed such mills could be used to prepare dry process feed. The first dry process plant had seven Griffin mills for rawmix grinding. As with the other designs, the mills ran "cold", and it was necessary to dry the crushed raw material before feeding to the mills, to prevent damp material from building up on the ...
