Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill, Coghill and DeVaney (1937) defined the ball size as a function of the top size of the feed, i.e.,
Aug 30, 2019· 1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the degree of ...
Oct 19, 2017· In our example, the grinding balls diameter needed to load into the mill must be equal to 40-50 mm. Let's sum up. The grinding balls diameter determined by the Bond formula has a recommendatory character and serves as a starting point for calculating the necessary proportion grinding media feeding a new mill.

Jan 01, 2013· A problem for solving mass balances in mineral processing plants is the calculation of circulating load in closed circuits. A family of possible methods to the resolution of this calculation is the iterative methods, consisting of a finite loop where each iteration the initial solution is refined in order to move closer to the exact solution.
Sep 07, 2011· Re: VRM and ball mill circulating load. Mainly in USA, the term circulating load is more often used than the circulation factor.Circulating load is percentage of coarse return in relation to fines & it can be calculated by : Coarse return TPH X 100 / Mill output TPH.Normal range of cirulating load in a conventional close circuit ball mill is around %.
Calculator: Chip Load. Calculator: Chip Load. Chip load is the depth of cut for each tooth on a milling cutter. Feed Rate: inches per minute RPM: Number of Teeth (or flutes): Result: Inches per tooth CHIP LOAD = Feed rate / (RPM x Number of teeth) Printer Friendly. Follow: Useful Links.
Here is a formula that allows you to calculate the circulating load ratio around a ball mill and hydrocylone as part of a grinding circuit. For example your ball mill is in closed circuit with a set of cyclones. The grinding mill receives crushed ore feed. The pulp densities around your cyclone are sampled and known over an 8-hour shift, allowing to calculate corresponding to circulating load ...
