Cement Grinding Stage. In raw grinding, a ball mill with a high efficiency separator is used to achieve uniform particle size in raw mix for the next stages of the manufacturing process. At the Cement Grinding Stage, 90 – 95% of the clinker is mixed with gypsum and ground in a Cement Ball Mill to produce quality cement OPC 43 and OPC 53.

The most typical approach, used for both grinding process control and completed cement testing, determines the surface area per unit weight of the cement. To do so, workers calculate the rate of airflow through a bed of cement. Other methods rely on the rate of sedimentation of the cement in kerosene or elutriation (separation) in an airstream ...

How cement is made. 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 …
