Reducing the Energy Required in Grinding Clinker to Cement ...

Grinding clinker to finished cement consumes more energy than any other comminution process. World production of cement in 2009 was 2840 million tonnes and the energy required for comminution was 40-60 kWh/tonne depending on the clinker characteristics and the fineness of the finished cement.

Choosing the Best Media Mill For Your Wet Grinding Application

Jul 01, 2003 · Regardless of flow rate or agitator speed, to achieve a target fineness of grinding, a specific amount of energy is required. Decreasing this energy requirement means having to run at higher milling efficiency. This is achieved by changing the grinding media, process milling method or using a more efficient mill.
