apr 01, 2015 the ball mill was simulated as a single compartment mill by eliminating the mill length of 2.935 m which was used in drying stage, such that the full length l 9.87 m of the mill was used in grinding. thus, drying of the raw meal outside the mill by an appropriate dryer was assumed.
ball mill grinding and classification circuit capacity was increased by 10 and specific energy consumption of the ball mill was decreased by 9.1. read more article
cement industry the ball mill was really an epoch-making breakthrough as for almost 80 years it was the predominant mill for grinding of raw materials and coal, and still today is the most used mill for cement grinding. over the last three decades the vertical roller mill has become the preferred mill for grinding of raw
aug 18, 2019 as for the dry grinding method, the moisture of raw material can affect ball mill capacity and quality. the higher the moisture content of the milled material will cause saturated or greasy so that the capacity and quality of ball grinding machine will be reduced. thus, the raw material with high moisture should be dried before grinding through
recent decades have proven the great effectiveness of a vertical roller mill for grinding raw materials. to calculate efficiency of the ball mill itself. the dry stirred mill and samples
