Optimum choice of the makeup ball sizes for maximum

A grinding circuit simulation combined with ball weal law was used to determine the optimum composition of the makeup ball sizes in tumbling ball mills. It was found that the optimum composition depends on various factors, including the feed size, the product size, the mill diameter and the breakage parameters. In all cases, binary mixtures of two ball sizes (50.8 mm and 25.4 mm) performed

Ball milling Digitalfire

Ball mills can be continuous or periodic, they can be small or gigantic, low speed or high speed, rotated or vibrated or both. For maximum efficiency a ball mill should be made of, or lined with, a porcelain or other very hard surface (so grinding also occurs between the wall and the balls), the balls should be of a range of sizes (to maximize points of contact), the mill should have the

How to Size a Ball Mill Design Calculator Formula

In this equation, E is the specific energy required for the grind, and F80 and P80 are the sizes in micrometers that 80% of the weight passes of the mill feed and product respectively. The parameter Wi, known as the work index of the ore, is obtained from batch bench tests first devised by Bond (1961). The power calculated on using equation 1, (Bond, 1961 Rowland and Kjos, 1978), relates to:

Calculate and Select Ball Mill Ball Size for Optimum Grinding

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. Well, this safety factor can cost you much in recovery and/or mill liner wear and
