Aug 02, 2014 Re: % of grinding media in ball mills for both chambers. The volumetric filling degree of modern finish mill is 27-30% for the first chamber and 24-27% for the second chamber.In your specific case first chamber may be loaded 114.76 MT- 127.52 MT and in second chamber you may load 197.91 MT - 222.65 MT.You should start media loading in both the chambers from lower value first and based

With this information, the Sensomag can determine the ball filling de-gree. The surveys consisted in varying the filling degree (25%, 30%, 33%) and for each value of J, the solid density was varied from 65% to 75% (average values). The mill was relined ahead of these tests and some surveys with

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

Figure 2 shows the active grinding area for an optimally charged ball mill. As the drum rotates, the media should ideally form a sloping pile that maintains a 45 degree angle so that there is a constant cascading of media at the surface. Because the media is falling the fastest and for the longest distance at the top of the pile, the majority

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 ...
