Increasing Clinker Quality through Automation. It is used primarily to make concrete, mortar, and grout. Portland cement manufacturing 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.
The other raw materials that are used in cement manufacturing, called additives, are high purity limestone, sand and iron ore. The high purity limestone is crushed in a lone in jaw crusher and then crushed more in a secondary crusher to reduce the size to completely pass through a 50mm sieve.
ball mill for raw materials for cement cement industry the ball mill was really an epochmaking breakthrough as for almost 80 years it was the predominant mill for grinding of raw materials and coal, and still today is the most used mill for cement grinding.

Cement is then pumped to silos for storage and dispatch. Mineral additions and SCMs are added to reduce the amount of clinker in cement. This in turn reduces the fuel, power, process emissions and raw materials associated with cement production. At the same time it creates a use for material considered to be a waste product of other industries.
