Everything you need to know about Refractories in Cement Manufacturing
Rotary Kilns. Modern rotary kilns can be safely lined with just two types of bricks: 1) high alumina in the calcin-ing and discharge zones, and 2) magnesia-spinel in the lower transition, upper transition, and burning zones. Many new kilns have been successfully commissioned with this simplified lining configuration, with good results.
