Corrected ball mill feed, and 3.T2 the particle size distribution of the corrected ball mill feed.With two equations and three unknowns, there are several solutions to equations 5 and 6, depending on the value attributed to the fines factor q1, each yielding different corrected ball mill feed size

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 (50.8 mm and 25.4 mm) performed better than a mixture of the three ball sizes.

Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial chargeor 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, dv 0 kf db ball size cm f feed size cm.

For temperature sensitive products ball mills can be fully jacketed to maintain temperatures of the product. Ball mills scale up well and in fact improve in performed with increasing size. Ball mills are available in sizes from laboratory scale (also called milling jars) of 0.1 usg to large 5 000 gallon 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 510 cm diameter but gradually wear away as grinding of the ore proceeds.

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. The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition.

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of 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. A ball mill consists of a hollow cylindrical shell rotati

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

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 Mill Circuit Classification System Efficiency. Ball mill feed and discharge size distributions associated with the same circulating load ratios are shown in Figure 3 These were produced by simulation but are almost identical to reported data from two operating plants Based on the circuit product size of 105 microns 150 mesh the estimated coarse solids inventory increases from 72 to 87

How Ball Mill Ore Feed Size Affects Tonnage Capacity. How ball mill ore feed size affects tonnage capacity. under the right operating conditions high power rate crushing can bring mill feed size down to near 80 passing 7000 microns and finer which can be handled more efficiently by ball mills based on average field observations the crushers can do this for less than half the energy and between

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

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.

The balls are initially 510 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

Feeding >15mm to a ball mill this size is not typical much larger ball mills (>21' or 7.0m diameter) typically get 12-16mm feed (from what I have seen in my experience) With regards to 3.5"- 4" media, typically for Ball mills of this size (16'), max size of ball used should be around the 50-60mm.

program. At the time of this research, mill ball charged, feed rate, and average moisture were 7 tons (ball size was 100 mm) per week, 720 t/h and 5%, respectively. Then, ball abrasion rate was calculated by Equations 4, 5 and 6. Total mill feed per week = 720*24*7*0.95= 114912 tons (4) Total ball charge per week = 7*106 g (5)

We are looking at a 1 MTPA comminution circuit that goes from a tertiary crush to a single ball mill (closed on a cyclone cluster) to produce a 100 µm P80 product. We're doing a trade-off study. Closing the tertiary on the screen or leaving it open! (The crushing plant runs 11 h per day, the mill 2

Feed rate With a high feed rate, less size reduction is effected since in this case the material is present in the mill for a shorter time. Properties of the feed material with a hard material, a smaller size reduction is achieved. Weight of balls With a heavy charge of balls, there is production of fine product. One can increase
