Describe Rotary Kiln In Civil Engineering Term

Rotary Kilns: The Rotary Kiln (RK) is one of numerous types of lime kiln technologies. The rotary kiln is a long inclined tube, about one hundred meters in length, fed with stone sizes ranging from 50mm down to less than 3mm. The rotation and the inclination of the tube force the limestone to roll from the top to the bottom.

How Concrete Is Made Material Manufacture

A modern kiln can produce as much as 6,200 tons of clinker a day. 2 The clinker is then cooled and ground to a fine powder in a tube or ball mill. A ball mill is a rotating drum filled with steel balls of different sizes (depending on the desired fineness of the cement) that crush and grind the clinker.
