(3) Grinding of raw meal: Cement process flow is divided into dry method and wet method. The dry method generally uses a closed-circuit operating system, that is, after the raw material is ground by the mill, it is sorted into the powder separator, the coarse powder is returned to the mill and then the grinding operation is carried out, and most of the materials are simultaneously dried and ground in the mill Process, the equipment used includes tube mill, intermediate unloading mill

Then the raw mix (the ground stone) passes through the firing stage in furnaces that reach 2000º C and is subjected temperatures in excess of 1450º C for 10 seconds. This produces an artificial rock, called clinker, which, when mixed with additives such as gypsum and other materials, is ground (grinding mill) to produce different types of cement.

sand stone... - Page 1 of 2 - International Cement Review
Re: sand stone... Hello Armankhan, Like sand, the role of sandstone is usually as a silica corrective. If used in the raw mix, sandstone is likely to be a source of coarse quartz (>45um) which, if present in large enough quantities and large enough particle size, may detrimentally affect the kiln feed burnability.
