In cement mills, ventilation is a critical key for maintaining temperature and material transportation. However, relationships between operational variables and ventilation factors for an industrial cement ball mill were not addressed until today. This investigation is going to fill this gap based on a newly developed concept named "conscious laboratory (CL)".

For this purpose, influences of 250, 350 and 450 g/t of dosages of an aminbased commercial GA on the cement grinding circuit was compared with the condition in which GA was not used. The effects of GA dosage on the ball mill and air classifier were examined in detail considering the change in the residence time of the material.

For a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically EUR per ton of cement. For an OK mill grinding a similar product, the cost of wear parts depends on the maintenance procedures, whether hardfacing is applied.

After exiting the cement kiln, the clinker is cooled and stored. To produce cement, clinker is mixed with a small amount of gypsum and other additives, such as pozzolans or slag. This mixture is then ground in the cement ball mill. The grinding process involves passing the clinker and additives through the rotating drum of the ball mill, where ...

Control Feed Size. The particle size of the material entering the ball mill is controlled between 2515 mm (the diameter of the ball mill is different for different feed sizes). Excessive rules will cause the ball mill to have too much fine material during the grinding process and cannot achieve the friction between the material and the material.
