2015-12-14 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

2009-1-1 1. Introduction. A Bond Ball Mill Work Index test is a standard test for determining the ball mill work index of a sample of ore. It was developed by Fred Bond in 1952 and modified in 1961 (JKMRC CO., 2006).This index is widely used in the mineral industry for comparing the resistance of different materials to ball milling, for estimating the energy required for grinding, and for ball mill

2015-6-6 Bond Work Index for Testing Procedure. Cleaning and Storing of Ball Mill Charge after the Bond Work Index Procedure is done: Add about 500 g of silica sand into the mill containing the ball charge. Seal the mill. Rotate for 20 revolutions to clean. Empty the mill charge and sand into the ball

It provides the Bond Ball Mill Work Index which expresses the resistance of material to ball milling. This happens after 7–10 grinding cycles, which shows that the procedure is a lengthy and complex one and is therefore susceptible to procedural errors.

The Bond Ball Mill Grindability Test is a locked-cycle laboratory grinding test. It provides the Bond Ball Mill Work Index which expresses the resistance of a material to ball milling. This Index is widely used in the mineral industry for comparing the resistance of different materials to ball milling, for estimating the energy required for grinding, and for ball mill scale-up.

2015-12-16 BOND BALL MILL GRINDABILITY The Bond ball mill grindability test is performed according to the original Bond procedure [4]. It requires 10kg of minus 6-mesh (3.35mm) material that is preferably prepared at the testing facility, by stagecrushing the sample to 100% passing 6-mesh, but normally less than 5kg are actually used in the test.

2001-10-1 Adopting slightly more rigorous laboratory procedures can significantly improve the precision of conducting these standard grindability tests. ln general, the Bond tests are quite repeatable. Within one laboratory, both rod and ball mill tests showed repeatability of less than ±4% at two standard deviations.

A Bond Ball Mill Work Index may also be used in the simulation and optimisation of existing mill(s) and the associated grinding circuit(s). Sample Requirements A minimum of 8 kg of material crushed to nominally minus 10 mm is preferred. JKTech would stage crush the sample to minus 3.35 mm as required for the Bond Ball Mill Work Index test feed.
