In a preheater kiln, the feed is calcined up to 30-35% in the preheater tower and thus the heat required, in terms of kcallkg clinker, within the rotary kiln proper, is much less, This makes it possible to obtain either higher pro duction rates on kilns of equal size or to maintain the same production rate by sizing the kilns much smaller.

During the cement production process, these minerals are fused together by heating them to just under their melting point, forming a cement clinker between 3 to 20 mm in diameter. Pure cement is formed when the cement clinker is ground into a fine powder. To regulate how cement mortar or concrete will set, gypsum is added to this powder.
