This paper differentiates scrubber and AG mill modelling in a similar way that overflow ball mills and grate discharge ball mills are analysed. Smaller scrubbers (600 kW) are suited to small scale ...
Sizing of cylpebs or ball media depends on the end product fineness and also the feed size. Selection of the mill lining; for soft minerals usually steel linings are used, sometimes with a high chromium content option, which reduces material discoloration.
Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones. Chat Now

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,, d↓V = K√F dB = ball size (cm) F = feed size (cm) Contact Supplier

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50% of the mill volume and its size depends on the feed and mill size. Get price

Sep 01, 2013· 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 ( mm and mm) performed better than a mixture of the three ball sizes.
Jun 01, 2018· For this coarser feed the 50 + 20+10 mm ball diameter mix breaks the material at a faster rate compared to the other ball matches. The availability of a ball size for a particular feed size ensures breakage occurs at a faster rate. The 10 mm ball size is unable to nip the large particle size hence the breakage rate is slower.
In the final study of the products close attention was given to sizing analyses, size by size, to see that the drag sand plus the overflow balanced the ballmill discharge. In the two tests shown in Table 33, the overflows are nearly identical.
Ball Mill an overview ScienceDirect Topics. Ball Mills. The ball mill accepts the SAG or AG mill product. Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore ...
Ball Mills Mineral Processing Metallurgy. A fine product demands the use of smaller balls than a coarse one, since the smaller particles of ore can be broken with a lighter blow, and, as has already been explained, in this type of mill the balls tend to grade themselves automatically in the conical discharge end according to size, the smallest balls lying in the smallest diameter.

Optimization of mill performance by using online ball and pulp measurements Soon after a stop, a mill is a dangerous place to enter for the personnel tasked with taking measurements or samples. Crash stops are difficult to handle. The mill and all feed streams should be stopped simultaneously but, often, they are stopped around about the same time.
