The mixture of materials is finely ground in a raw mill. The resultant raw mix is burned in a rotary kiln at temperatures around 4482 degrees Celsius to form clinker. The clinker nodules are then ground with about 3 % gypsum to produce cement with a fineness typically of less than 90 micrometers . Production Processes

As the production begins, the sand and gravel are gravity fed into the weigh batcher which measures the proper amount of each material. The dry materials then flow into the mixer, which blends them together with a small amount of water, for several minutes. This "dry mix" is now easy to manipulate and ready to be molded.
