Cement Kilns: Suspension preheater kilns

The upward gas velocity is sufficient for the powder to be picked up and lifted up the duct "in suspension" in the gas. Because heat exchange occurs over the vast surface area of the individual mineral particles, the gas and rawmix reach a common equilibrium temperature in a fraction of a second. The solids and gas are then separated in a cyclone.
