The energy consumption of the total grinding plant can be reduced by 2030 % for cement clinker and 3040 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended.

As a general rule, there should be less than 25% of clinker that is below 1mm in size. Coarse clinker is more of an issue for ball mills. Some cement groups use a formula, such as Bond's, to calculate the maximum ball size required in a ball mill, based on the average size of the clinker feed.

Clinker grinding technology is the most energyintensive process in cement manufacturing. Traditionally, it was treated as "low on technology" and "high on energy" as grinding circuits use more than 60 per cent of total energy consumed and account for most of the manufacturing cost. Since the increasing energy cost started burning the benefits significantly, the [.]

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 ...

Narrow size fractions of a Portland cement clinker and a chromite sample were used as the experimental materials. The size fractions of both samples coarser than mm were used in the singleparticle impact loading tests. Ball mill grinding tests were performed with the narrow size fractions of the clinker sample finer than mm.
