Manufacture of cement – consists of mixing, burning, and grinding processes. 1. Mixing: It may be a wet process or by dry process. In a wet process wash mill is used which is a heavy cylinder of 2.5 to 3.0 m in diameter and 9 to 12 m in length. It is kept slightly inclined to the horizontal and can rotate at 15–20 revolutions per minute.

Advantages: The wet process of cement production has the characteristics of simple operation, low dust and easy transport. The slurry has good fluidity, good homogeneity, and the quality of the clinker is improved. In addition, the energy consumption of raw material grinding in wet processes is reduced by almost 30%.

The steps involved in the wet process are described below: Fig.: A wash mill The raw materials are crushed and fed into a wash mill. A small amount of water is added to the ingredients and the grinding action in the mill is propelled by the presence of steel balls. These balls further pulverize the entire mass and a slurry is formed.

Four manufacturing processes are, or were, in use: • The wet process. The raw material is ground in water (30-40 % of water) and treated in a long kiln (up to 250 m). This process has practically been discontinued. Only one plant was using this process in 2001, among 20 cement plants that were operating in France. • The semi-wet process.
