The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.

The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index. For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure 3.10), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material ...

12/3/2010 · Re: Ball Mill Load & feed. Dear GKS, You are correct in stating that main drive kw only increase when less grinding media charge and small size of grinding media w.r.t. feed size and feed rate. However, it was to be stated in my reply that Kwh/t of material increases in chocked condition of the mill as there is no output from the mill. Warm regards

First, a Jar Mill grindability test requires a 5 lb. (2 kg) sample and produces a direct measured specific energy (net Hp-hr/t) to grind from the design feed size to the required product size. The second test, a Bond Work Index determination, results in a specific energy value (net Hp-hr/t) from an empirical formula.

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. d↓V = 0.40 K√F dB = ball size (cm) F = feed size .
