Mill Type Overview. Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns.; The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns.; The CenterPeriphery Discharge mill has feed reporting from both ends and the product discharges ...
The Bond work index of chromite ores were determined using the standard Bond ball mill test (Mosher and Tague, 2001; Morrell, 2008). Work index (W i ) is found by simulating dry grinding in a ...
First, a Jar Mill grindability test requires a 5 lb. (2 kg) sample and produces a direct measured specific energy (net Hphr/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 .
The ability to simulate the Bond work index test also allows examination of truned 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 ), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material ...

MODELING THE SPECIFIC GRINDING ENERGY AND BALL The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ...
Bond ball mill work index (BBMWI) test is a standard test used to measure the ball mill work, which is calculated in accordance with the procedure proposed by the Bond [21]. The BBMWI determines how much energy is needed to grind a sample of ore in a ball mill [22]. This measurement is expressed in kilowatthour per ton (kWh/t), which is the ...
The ore properties passing through an AG/SAG mill often changes unexpectedly. If it does, you need a test that you can do in the lab on site to quickly predict what you can do to prevent losses. In this exercise you can simulate the effect of a different Bond Work Index.

Jul 15, 2013 · See this useful summary Table of Bond Work Index by Minerals. For any circuit, whether a crushing circuit, a rod mill, or a closed ball mill circuit, the Work Index always means the equivalent amount of energy to reduce one ton of the ore from a very large size to 100 um. The sample was received crushed appropriately for the ball mill test.
Jan 15, 2018 · The Bond Ball Mill Work index (BBWi) is the industry standard procedure for assessing the grindability of ores. The test involves conducting a lockedcycle grinding test using Bond's standard mill design. The lockedcycle test enables a batch process to emulate the grinding behaviour of a continuous mill with a 250% recirculating load.
