The invention is particularly intended for ball mills, or mills with similar grinding instruments, for cement, in a closed circuit. Generally, these mills have two compartments, namely a preparing compartment with balls with a diameter of 90 to 60 mm and a finishing compartment with balls with a diameter of 40 to 20 mm.

Slag cement, originally known as granulated blastfurnace slag, begins with the production of iron. The heart of the process is the blast furnace that refines iron ore into iron. The ingredients are heated to nearly 1500 degrees Centigrade to form two components: iron and molten slag. The iron is used to produce steel, and the molten slag is ...
Flexible, modular design Low pressure drop Simple maintenance Cement grinding is a crucial stage of the flow sheet, where both cement quality and process e ciency are decided. Achieving the required fineness with maximum e ciency is down to the design of the ball mill and how well it runs.
