Limestone Analyses via Bond Work Index For full scale onsite Limestone Analyses via Bond Work Index limestone is typically received with a diameter of about 1 in. (25 mm) fraction (underflow) is returned to the ball mill.
Numerically, the work index is the energy required in kwh/t to reduce a given material from theoretically infinite feed size to 80% passing 100 microns. The 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.

CORRELATION BETWEEN BOND WORK INDEX AND . The Bond''s standard ball mill is used to determine the work index value of differ ent samples. The Bond work index is defined as the kilowatthours per short ton required to break from infinite size to a product size of 80% passing 100 #181;m.
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 lt;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. If you
The Bond work index determination according to the standard Bond''s test is done on all these samples with comparative sieve size of 74, 105 and 150 microns. The Bond Work Index is calculated using the formula (Bond, 1961): ( ) (1) where: W i Bond work index (kWh/t); P c test sieve mesh size (#181;m); G weight of the test sieve

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 ), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material

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 ).
