Cement Kilns: Size Reduction and Grinding

In cement grinding, the tube mill established itself as a complement to the ball mill, and they were installed in pairs, with the ball mill discharging directly into the tube mill inlet. They often worked on a common drive. Tube mills were also used in combination with flat stones, the latter being run "light" so that stone wear was minimised, and greatly increasing their output. During the ...

Cement Milling - Understanding Cement

Cement milling is usually carried out using ball mills with two or more separate chambers containing different sizes of grinding media (steel balls). Grinding clinker requires a lot of energy. How easy a particular clinker is to grind ("grindability") is not always easy to predict, but large clusters of belite due to coarse silica in the feed are difficult to grind. Rapid cooling of the ...

Raw Material Preparation - Cement Plants and Kilns in ...

From the early 1900s, both for cement grinding and for grinding hard raw materials, whether by wet or dry process, the standard arrangement was a ball mill for preliminary grinding (to below 0.75 mm), followed by a tube mill for fine grinding. Typically the ball mill was placed on an upper floor so that material could move by gravity. An example was the original rawmill system at Aberthaw ...

The cement mill

Cement manufacturing - brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds. The drum is generally divided into two or three chambers, with ...
