Cement is conveyed from grinding mills to silos (large storage tanks) where it is packed in 20-40 kg bags. Most of the product is shipped in bulk quantities by trucks, trains or ships, and only a small amount is packed for customers who need small quantities. Chemical Reactions during Cement Manufacturing.
Manufacturing Cement Grinding. The clinker is combined with small quantity of gypsum and then it is finely ground in a separate mill to get the final product. The mill is a large revolving cylinder containing steel balls that is driven by a motor. The finished cement is ground so fine that it can pass through a sieve that will hold water.

Aug 20, 2015 Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 C in a cement kiln. In this process, the chemical bonds of the raw materials are broken down and then they are.
Step 6 Finish Grinding. 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.

The power ingesting of a grinding process is 50-60 in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40 associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time. Read.
