Rotary Kilns - KHD International

Kiln plants with two and three station rotary kilns from KHD Humboldt Wedag are top of the line. One reason: highly efficient precalcining systems, which were developed by KHD Humboldt Wedag, revolutionizing the clinkering process. Rotary kilns no longer have to function as calciners which mean that they can be substantially smaller in size.

The rotary kiln has a number of zones, namely calcining zone, heating zone, liquid/burning zone, sintering zone and cooling zone. Once partial calcination is achieved, these are subsequently completely calcined in a rotary kiln and heated to approximately 1,400 degree Celsius in the sintering zone of the kiln.
