Calculate and Select Ball Mill Ball Size for Optimum Grinding

02-08-2013  In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”.

Optimization of mill performance by using

Further investigation will be conducted in an industrial mill to determine the optimum media filling degree for a specific application. This paper illustrates this point for a grate discharge mill. For a specific production rate in the pilot plant, an increase in the balls level from 25% to 30% leads to an increase in product fineness.

Ball Mill Loading - Dry Milling - Paul O. Abbe

The starting point for ball mill media and solids charging generally starts as follows: 50% media charge; Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space; Add to this another 10%-15% above the ball charge for total of 23% to 25% product loading.

Ball Mill Loading - Wet Milling - Paul O. Abbe

As with dry milling there should be at least 25% liquid to fill the void space plus a bit more to insure the balls are striking product and not each other. Of course the surface tension of the liquid used will greatly affect the ability of the solids to be both suspended in the liquid and to form a film on the grinding media.

Ball Mill Design. A survey of Australian processing plants revealed a maximum ball mill diameter of 5.24 meters and length of 8.84 meters (Morrell, 1996). Autogenous mills range up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and 1.8:1.

Grinding Balls Rods - Mineral Processing Metallurgy

The original charge to a mill is generally between 40% and 50% of mill volume for ball mills and 35% to 45% mill volume for rod mills. As a general figure rod mills will have a void space within the charge of around 20% to 22% for new rods. In ball mills the theoretical void space is around 42% to 43%.

Based on deep belief network (DBN) and support vector machine (SVM), a novel soft sensor approach is proposed in this paper to solve the problem of measurement of fill level inside the ball mill. This measurement methodology of ball mill fill level using the DBN based soft sensor can be structured in two consecutive stages: first, DBN is employed to construct a deep architecture to obtain the high level representation of the vibration frequency spectrum of the ball mill
