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.
