Here is the old Allis-Chalmers Bond Work Index Grindability Test Procedure. The standard feed is prepared by stage crushing to all passing a 6 mesh sieve, but finer feed can be used when necessary. It is screen analyzed and packed by shaking in a 1000-cc graduated cylinder, and the weight of 700 cc is placed in the mill and ground dry at 250 per cent circulating load.

A Bond Rod Mill Index Test (BRMWI) is a standard test for determining the Rod Mill Work Index of a sample of ore. The BRMWI is a measure of the resistance of the material to crushing and grinding. It can be used to determine the grinding power required for a given throughput of material under rod mill grinding consitions. JKTech Pty Ltd
The test is a batch test, run with 2 kg of ore in a standard 10 cm diameter by 30 cm long mill, and it measures the time (in minutes) required to grind a sample from 80% passing 12.5 mm to …

Improving knowledge of grinding technology and mill operations to operate, optimise and troubleshoot ball mill and vertical roller mill grinding installations. Ball mills and vertical roller mills are used for many grinding applications in cement production: raw meal grinding, coal and pet coke, and finish cement grinding.
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
When making comparisons of the efficiencies of different grinding and crushing machines it is desirable to be able to estimate the work actually done in crushing the ore from a given size of feed to a given size of product, the screen analysis of both feed and product being determined. Messrs. Klug and Taylor, in a paper on this subject, published in the monthly journal of the Chamber of Mines ...

The first step in minerals beneficiation of an ore is normally crushing which has been defined "as the operations required to reduce run-of-mine ore to grinding feed size". It would therefore follow that the first metallurgical testing should be conducted on run-of-mine ore but, due to its size, this would be rather impractical. However, there is little need to test large rocks because ...

1 Over the past 15 years, mine-to-mill studies have focused attention on the impact blast fragmentation has on concentrator throughput. Blasting provides the first opportunity for comminution – or size reduction. It is also a cheaper and more efficient process, compared to both crushing and grinding.
