Bond Work Index Formula-Equation. 2018-7-19 · 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.
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.

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).
The grinding jar for the Bond Index Rod Mill is 12″ x 24″ in size and has a wave-shaped design. At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill. The Rod Mill Work Index (RWI) is used for particle size determination in a size range from 25 mm down to 2.1 mm whereas Ball Mill Work ...

The Bond rod mill work index is not as common as the Bond ball mill work index, and there are two different variations on the mill apparatus.The SAGMILLING.COM models expect a mill with a "wave liner", and is not compatible with mills using "smooth liners".
The Bond ball mill work index test is thought to be additive because of its units of energy; nevertheless, experimental blending results show a non-additive behavior. The SPI(R) value is known not to be an additive parameter, however errors introduced by block kriging are not thought to be significant . …

Bond Ball Mill Index Test (BRMWI) A Bond Ball Mill Index Test (BBMWI) is a standard test for determining the Ball Mill Work Index of a sample of ore. The BBMWI is a measure of the resistance of the material to crushing and grinding.
using Bond rod mill work index (RMWI), and Bond ball mill work index (BMWI). However, the author has developed a relationship between the Bond third theory SE values and the AG/SAG SE values to enable the additional power required for AG/SAG milling to be determined.
Ball mill is used for determining the power requirement by ball milling as per invention of F. C. Bond. The standard feed is prepared by stage crushing to all passing 6 mesh sieve.
A grinding mill (Φ305 mmˆ305mmˆmmˆ305 mm) was used for the Bond ball mill work index test [18] [19] [20][21]. This ball mill was filled with 285 steel balls (total weight of 20.125 kg) at an ...
