ensp·enspJKTech Laboratory Services 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.
test method for bond ball mill work index
The Bond ball mill work index is one of the most commonly used grindability tests in mining, and is often referred to as the Bond work index.. The test is a 'lockedcycle' test where ground product is removed from test cycles and replaced by fresh feed.
A developed approach based on grinding time to determine ...
Bond work index is estimated by using a standard bond ball mil.. In this study, one special ball mill was used to perform bond tests by which bond work index can be precisely obtained. This ball mill was designed and set up by Nematollahi [15], and is commonly called "calibrated bond ball mill".

MultiCompartment Rod/Ball Mill Evaluation on Bauxite ...
Rod mills generate small amounts of fines, as fine particles typically accumulate in the space between rods without enduring comminution [2]. Effective grinding of this material occurs in the ball mill compartment, generating finer fragmentation. The Bond Rod Mill Work Index (BRMWI) test was only possible for Blend 5 (Table 2) due to excessive
