Grinding mill is made of wear-resistant steel ball, there are many factors influence the ball grinding productivity. Generally speaking, the same specification of steel balls' density is of high productivity and low density is of small productivity. mining industry Now brief analyses the effects of ball …
The specific rates of breakage of particles in a tumbling ball mill are described by the equation S i = ax α i (Q(z), where Q(z) is the probability function which ranges from 1 to 0 as particle size increases.This equation produces a maximum in S, and the particle size of the maximum is related to ball diameter by x m = k 1 d 2.The variation of a with ball diameter was found to be of the form ...
The mill (with 30 cm in diameter and 30 cm in length) and the test conditions are standardized, with a maximum ball size of 40 mm and an ore top size of 3.35 mm. With less than 300 balls, it poses no challenge in running the simulations, if only grinding media are included.
The effect of ball size distribution increased with increasing mill filling and for the mill filling of 35%, the ball size distribution had the maximum effect on the power draw. When the mill charge

Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
This study on the effects of particle filling and size on the ball load behaviour and power in a dry mill was initiated at the University of the Witwatersrand in 2003.

Effect of Ball Size and Properties on Mill Grinding Capacity Current ball milling theory suggests that grinding capacity is influenced by the size of balls charged to the mill. In selecting the appropriate ball charge, the first objective is to determine that ball size which will …
Ball size is a critical parameter influencing the performance of a ball mill, particularly for multi-compartment ball mills used in cement industry. Studies for selection of optimum ball size are reported in the literature ( Tarjan, 1981 ; Duda, 1985 ).
Ball size distribution The ball load in the mill, prior to the removal of the scats, was calculated from the volumetric filling, taken from the full grind-out to be 70t.

The ball mill crushes materials through the impact and grinding effect of the grinding media. In this process, the steel ball is used a medium of energy to transform the outside energy to the crushing forces, thus completing the materials crushing process. Apparently, the energy carried by the media is determined by the size of the media, which determines the crushing force, grinding ...
Ball size distribution The ball load in the mill. the top size of the scats. For a normal finer ball size distribution a finer grind and lower throughput would be expected. The average scats size distribution was taken from the 6 test runs.
