It is usually used with a cyclone preheater, in which raw meal will be preheated and decarbonated before entering the kiln so that the kiln body can be shorter and of smaller diameter. This reduces the costs of the new cement plant. However, the fluidity of powder is worse than slurry, so the uniformity of the raw meal is relatively worse.
