Earlier we considered a mixture of which materials is used in cement production. The base of this mixture is a clinker. In this article, we will consider the composition of clinker and its impact on grinding balls deterioration in milling process. Clinker (in cement industry) is transitional product in cement production. Upon heating mixture obtained from limestone (about 75 ) and clay (about.The clinker is ground in a ball mill—a horizontal steel tube filled with steel balls. As the tube rotates, the steel balls tumble and crush the clinker into a super fine powder. It can now be considered Portland cement. The cement is so fine it will easily pass through a sieve that is fine enough to hold water.
The hot clinker is used to preheat the air for burning the coal, and the cooled clinker is stored ready for use. Cement milling. The clinker is finely ground with about 5 gypsum in another ball mill, producing cement. (The gypsum regulates the early setting characteristic of cement).Taking grinding P o42.5 cement as an example, the pre grinding closed loop system composed of roller press or external circulation vertical mill and powder concentrator has a circulation load rate of 200 – 300 , and the specific surface area of the selected materials is 180 280m 2 kg. The following table lists the main machine.
