In the last period, a new concept of clinker grinding has emerged, which achieves a reduction in electricity consumption. The process consists of passing the clinker through a roller mill that works at high pressure and acts on a layer of clinker. This process cannot be confused with the crushing of the clinker, whichاحصل على السعر
