Kinetic grinding test approach to estimate the ball mill work index 343 The W i parameter is obtained from Bond''s ball mill grindability test (Bond, 1961). This test is performed according to the standard Bond procedure which proposed model is presented in Eq. 1. This standard grindability .
This Grindability Test or Bond Ball Mill Work Index Procedure is used to determine the Bond Work Index of minus six mesh or finer feed ore samples. These equation application methods are used to process <1/2″ ore samples in a Ball Mill using a standard ball charge. Below describes in general terms the Bond Work Index Procedure used by a Professional Metallurgical Testing Laboratory.
Aug 10, 2017· Ball mill charge size distributions originally specified for Bond grindability tests to determine the Bond Work index (BWi) are not commercially available. Those proposed to date do not match all of Bond''s (1961) original specifications of total ball mass, number and surface area.
Determination of the energy consumption for ore grinding in a Bond ball mill requires samples of standard size, because changes in the size of the samples cause the change of the Bond work index (Magdalinovic et al., 2012). Due to the Bond test complexity .
out by sieving with a 120mesh size. Bond Index and grindability of the mill were calculated using the amount of fines per revolution. Scope of the experiment is given in Table 1 and the experimental set up is shown in Fig. 1(A). Mechanism of operation in a ball mill is shown in Fig.1(B).

Ball mill charge size distributions originally specified for Bond grindability tests to determine the Bond Work index (BWi) are not commercially available Those proposed to date do not match all of Bond''s (1961) original specifications of total ball mass, number and surface area.
Standard grindability test for ringroller/ball mill is required for biomass Bond Index test can be used for biomass for analysing grinding performance of biomass in tube and ball mill Matching P 80 to classifier particle size critical in optimising mill performance Predensified particle size .
Numerically, the work index is the energy required in kwht to reduce a given material from theoretically infinite feed size to 80 passing 100 micronshe work index of a particular material is determined in the laboratory by conducting the standard bond grindability test bond developed separate tests for the rod mill and the ball mill.
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 .

International Journal of Emerging Technology and Advanced Engineering593 Кб. Different C++ programmings were written to compute energy requirement, work input and grindability for the ball mill using the above mentioned systemThe results for the Bond work index grindability thus obtained may differ substantially with different standard Bond ball mills (Kaya et al., 2003).
Bond Index Hardgrove Grindability Index Tests for, Bond Index Test Test conducted on a Bond Index testing mill (BicoBraun, USA) 700ml of sample milled for 100 revolutions New number of revolutions is calculated to produce fines equal to 1/35 of the total charge of the mill The Bond Work Index W i expresses the resistance of the material to...
Ball mill design requires a Bond work index, BWi, for ball mills at the correct passing size; SAG mill design requires an appropriate SAG test, for example, SPI (Chapter 5). Flotation design needs a valid measure of kinetics for each sample, including the maximum attainable recovery and rate constants for each mineral ( Chapter 12 ).

Bond Rod Mill Grindability Test. The test determines the Bond Rod Mill Work Index which is used with Bond''s Third Theory of Comminution to calculate net power requirements when sizing ball mills*. Various correction factors may have to be applied. The test is a closedcircuit dry grindability test performed in a standard rod mill.
