CLINKER GRINDING IN CEMENT PRODUCTION

21/02/2019  Clinker grindability is determined by quantity of electricity consumed for grinding (kW / ton) under other equal conditions. In cement production entire crushing and grinding process consumes about 85% of the electricity. At the same time 75% of electricity consumed for milling and only 2-20% of them consumed for grinding. According to some hypotheses, only a thousandth blow of the ball is spent on grinding the material. Thus, cement plants are among the most demanding for grinding

Cement clinker - Wikipedia

Gypsum is added to clinker primarily as an additive preventing the flash settings of the cement, but it is also very effective to facilitate the grinding of clinker by preventing agglomeration and coating of the powder at the surface of balls and mill wall. Organic compounds are also often added as grinding aids to avoid powder agglomeration. Triethanolamine(TEA) is commonly used at 0.1 wt. % and has proved to be very effective. Other additi

CLINKER GRINDING UNIT PROCESS - Mechanical

In clinker grinding, gypsum being the more readily grindable, tends to be concentrated in the finer particle size fraction of the product. Strength development improves if cement is more closely graded, provided the specific surface of cement is not reduced. Improvement in strength is due to faster rate of hydration.

Fineness of grind is dependent upon the type of cement to be produced. Since fineness of grind falls below standard screen size accuracy, fineness of grind is determined by use of a “Wagner’’ Turbidometer. Desired grind then is expressed for example

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.
