The level of accuracy that can be achieved through IIoT is one of the biggest advantages For example, during cement grinding in a cement mill, the mill operator might perform excessive grinding of material even when the required fineness of cement is achieved, this result in over-grinding and extra energy. The grinding process can be optimized by using the historic data of clinker feed and mill speed to achieve the required fineness without extra grinding

How to Improve Cement Ball Mill Performance in

There are two methods for clinker pretreatment: pre-crushing and pre-grinding. 1) The pre-crushing uses a crusher to crush the clinker before grinding, which can reduce the diameter of clinker particle to 5 ~ 8mm. 2) The pre-grinding adds a roller press to the cement grinding system. In this system, the clinker is extruded circularly, dispersed and separated, and becomes powder with diameter less than 2 mm;
