Reactions in the cement kiln - clinkering

In a wet-process or preheater system without a pre-calciner, most of the calcination takes place in the rotary kiln within a moving mass of feed. This situation is not ideal for calcination because heat transfer has to take place through a large mass of material and CO 2 has to escape outwards as heat moves inwards.

homogenization | Definition & Examples | Britannica

homogenization, process of reducing a substance, such as the fat globules in milk, to extremely small particles and distributing it uniformly throughout a fluid, such as milk.When milk is properly homogenized, the cream will not rise to the top. The process involves forcing the milk through small openings under high pressure, thus breaking up the fat globules.
