Influence of Kiln Speed on The Operation of Rotational Kiln

The rotary kilner is the technical transformation kiln, with large diameter ratio, so the resistance of the kiln air flow is larger than the average kiln, and kiln pressure of about -200Pa. After increasing the kiln speed, the fill rate of the kiln material from 13.75% to 10.70%, to enhance ventilation.

Cement Kilns: Design features of rotary kilns

The rotation of the kiln lifts the feed up the side of the kiln, and the energy required to maintain its centre of gravity above the lowest (6 o'clock) point is the main component (80-90%) of the energy consumed. In the case of kilns containing curtain chains, these also produce an eccentric load. Rotary kilns have always had variable speed drives.
