Cement kiln Wikipedia

A typical process of manufacture consists of three stages: grinding a mixture of limestone and clay or shale to make a fine "rawmix" (see Rawmill) heating the rawmix to sintering temperature (up to 1450 °C) in a cement kiln grinding the resulting clinker to make cement (see Cement mill). In the second stage, the rawmix is fed into the kiln and gradually heated by contact with the hot

Cement Milling

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

How to calculate the grinding time of the ball mill

The pulp should have a volume of 18.5*25%=4.56m3 in the ball mill. Then the minimum grinding time = 4.56/1.35=3.38min Note: When the grinding time is the shortest grinding time, it is ideal when the large block is directly ground to the granule size, and there is no overgrinding phenomenon. This value is only for theoretical calculation.
