Effects of Ball Size Distribution and Mill Speed and Their Interactions on Ball Milling Using DEM. A comprehensive investigation was conducted to delineate the effect of ball size distribution, mill speed, and their interactions on power draw, charge motion, and balls segregation in a laboratory-scale mill.

Get PriceFurther, the ball size distribution in the mill is not a simple parameter that can be controlled directly, as it depends on the make-up ball charge and wear rate. Therefore, the industrial practice of determining the make-up ball sizes comes down to experience.

Get PriceMill performance and ball size distribution are so intimately related that it is crucial to better understand their interrelation. This then orientate process engineers in choosing the optimal ball charge mixture. For the first time, Concha et al. (1992) ...

Get PriceBall mills can be designed to operate continuously (fed at one end of the system and discharged at the other), or on a batch basis for smaller, or intermittent volumes. They can also be operated either on a stand-alone basis ('open-circuit grinding') or in conjunction with a classifier which returns oversize product to the mill for further grinding ('closed-circuit grinding').
