Cement Kilns: Grate Coolers

The waste air stream is another distinct disadvantage of the grate cooler design, and limited its popularity until the 1980s. Rotary and planetary coolers operate under suction and although noisy, produce little atmospheric pollution. The waste air of a grate cooler naturally contains a large amount of gritty clinker dust.
