The suspension preheater is the basis of all modern systems. Rawmix in dry powder form is injected into hot kiln exhaust gas in a vertical duct. 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 ...
