Understanding the Difference Between Raw Mill and Cement Mill

The primary difference between raw mill and cement mill is the raw materials that are being used. In the case of raw mill, the raw materials are milled into a fine powder and then heated in a kiln to produce clinker. In the case of cement mill, clinker is produced from the clinker nodules that are ground in the cement mill.
