Rotary kiln process

Apr 07, 2020 Rotary kilns can be divided into cement kilns, metallurgical chemical kilns and lime kilns according to different materials processed. Cement kilns are mainly used for calcining cement clinker, divided into two categories: dry process cement kilns and wet process cement kilns
