Cement Analysis and Production Information | Thermo Fisher
These additives, along with the limestone, are fed from bins to the raw mill. An extremely important step in the cement process is to proportionally feed these materials to the raw mill to ensure the correct “blend” of these materials. One can think of this process as a “recipe” for making various types of cement.

The proportion of the mill-exit material returned to the inlet may vary from 10-30% when ordinary cement is being ground, to 85-95% for extremely fine cement products. It is important for system efficiency that the minimum amount of material of finished-product fineness is returned to the inlet.
The Cement Manufacturing Process - Advancing Mining
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.
Filter bag in the process of cement mill in Malaysia
Filter bag in the process of cement mill in Malaysia. A cement mill is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
