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.

cement - cement - Extraction and processing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.

One of the fundamentals of cement manufacturing is to ensure the right chemical composition of the cement raw mill. A raw mill with a superior fineness and well-controlled chemical composition using as advanced control system can improve the cement quality and define critical cement craft parameters.

processing units are crushers unit, raw mill, homogenizing plant, kiln system, cement mill and packing plant. Here, dry production process is used because energy consumption is less and running cost is also lower compared to other process. The raw materials used are in the following compositions; limestone 95-97% and laterite 3-5%.

Cement powder, in its initial state, is 'anhydrous,' meaning without water. That is if the small quantity of water present in any gypsum added to the grinding stage is ignored. By the process of reaction with water, cement powder mixed with water, sand, and gravel results in the synthetic rock called concrete. This reaction with…
