SLAGGING ROTARY KILN INCINERATOR

SLAGGING ROTARY KILN INCINERATOR (Abstract) The rotary kiln is a horizontal cylinder, lined with refractory, which turns about its longitudinal axis. Waste is deposited in the kiln at one end and the waste burns out to an ash by the time it reaches the other end. Kiln rotation speed varies in the range of 0.05~0.5 revolutions per minute.
