An improved method using less mass compared to the Bond Ball Mill Work Index test. The JK Bond Ball Mill (JKBBM) test, is a locked cycle grindability test conducted using a standard laboratory Bond Ball Mill with the same steel ball charge and material feed size ( passing 3.35 mm) as the Bond Ball Mill Work Index test.
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.
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 closed-circuit dry grindability test performed in a standard rod mill.
The Thirty-nine samples were submitted for the Crusher Index (Ci), SAG Power Index (SPI®), Standard Bond Ball Mill Work Index (BWI) and Modified Bond Ball Mill work Index (MBI) tests. The Ci, SPI® and Bond Wi values of these samples show a good indication of ore hardness variability within the ore body.
JKTech would stage crush the sample to minus 12.5 mm, as required for the Bond Rod Mill Work Index test feed. JKTech can prepare a representative sample, stage crushed to minus 12.7 mm, from a larger sample of ore if required.
Bond developed a standard laboratory test for the determination of the work index for ball and rod mills in 1952 and modified it in 1961. The standard Bond ball mill grindability test is a closed circuit dry grinding test with a 250% circulating load. The standard procedural outline of the test is stated in (Bond) 1961. The work index for a ...
