Rotary Kiln Xingyuan

Rotary kiln refers to rotary calcination kiln (commonly known as rotary kiln) and belongs to the category of building materials equipment. 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.

Rotary kilns (sometimes called calciners or rotary furnaces) are used for thermal treatment processes such as calcination, sintering, pyrolysis and firing, as well as for oxidation and treatments can be applied to powders, granulates, suspensions and green bodies.a rotary kiln consists of a cylindrical, rotating body mounted between stationary material feed and outlet housings.

Rotary kilnsrotating industrial drying ovensare used for a wide variety of applications including processing raw minerals and feedstocks as well as heattreating hazardous wastes. they are particularly critical in the manufacture of portland cement. their design and operation is critical to their efficient usage, which if done incorrectly.
