Burning and Grinding. After mixing the materials in appropriate proportions, the mixture is burned at a high temperature. Here the chemicals go through some reactions and are turned into calcium silicates which form the cement clinker. The cooled pellets are then ground in ball mills or tube mills and during this grinding process, a small proportion of gypsum is added. In cement, gypsum acts ...

This reduces the capital costs of a new cement plant. A dry process kiln might be only 70m long and 6m wide but produce a similar quantity of clinker (usually measured in tonnes per day) as a wet process kiln of the same diameter but 200m in length. For the same output, a dry process kiln without a precalciner would be shorter than a wet process kiln but longer than a dry process kiln with a ...

Reactions in the cement kiln - clinkering

In the burning zone, above about 1300 °C, reactions take place quickly. The clinker is in the burning zone for perhaps 10-20 minutes but in this time a lot happens: The proportion of clinker liquid increases and nodules form. Intermediate phases dissociate to form liquid and belite. Belite reacts with free lime to form alite. Some volatile phases evaporate. Clinker liquid and nodule formation ...

Cement Kilns: Early kilns

Early kilns used for cement burning were “static”, either batch-process kilns based upon the primitive egg-cup shaped traditional lime kiln, or later, “shaft” kilns which operate continuously. One frequently encounters references to open lime kilns being operated continuously, with periodic withdrawal of small amounts of product, and topping up with raw material and fuel. This was ...
