2. CEMENT MILL A schematic representation of the cement milling circuit is depicted in Fig.1. Cement milling circuit is an industrial process, which takes raw material as input and which produces cement.
Cement Milling. Cement milling is usually carried out using ball mills with two or 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.
Cement manufacturing . The ball mill has a vital role in the cement manufacturing process. The mixed raw materials (cement raw meal) before cement production and the finished products (cement clinker) after cement manufacture need to be ground by cement ball mill.
This is achieved in a cement raw mill. The grinding process is controlled to obtain a powder with a broad particle size range, in which typically 15 by mass consists of particles below 5 μm diameter, and 5 of particles above 45 μm. The measure of fineness usually used is the specific surface area , which is the total particle surface area.
