Rotary Kiln Handbook NEW PDF Refractory Differential
网页A quality refractory is of the utmost importance, and many options are available, depending on the needs of the rotary kiln. Refractory is specific to direct-fired kilns; the addition of refractory to an indirect-fired kiln would decrease efficiency, because it would add another layer for heat to pass through before it could reach the material.

Rotary Kilns Refractories: What to Know! Ganesha's
网页2022年6月27日The only rotary kilns that use refractory are direct-fired, while indirect-fired kilns transfer heat primarily through the wall of the kiln. As another barrier, refractory reduces the efficiency of the process as heat passes through it before it meets the material. Therefore, indirect-fired kilns use heat-resistant materials instead of refractory.
