Bond Ball Mill Index Test
The tried and tested measure of ore grindability.
A BBMWI test 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. It can be used to determine the grinding power required for a given throughput of material under ball mill grinding conditions. It is a 'locked cycle' test conducted in closed circuit with a laboratory screen.
A Bond Ball Mill Work Index test may be required for the design of a new mineral processing plant. Where possible, it is carried out on a sample of ore that is typical of the proposed feed to the plant.
The BBMWI is then used in the design calculations of the new grinding circuit. A BBMWI may also be used in the simulation and subsequent optimisation of existing mill(s) and the associated grinding circuit.
Sample Requirements:
1. A minimum of 10 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. When a drop-weight test is also being carried out, sufficient sample should be available from the drop-weight test residue.
2. Download the Sample Transmission Forms, which include Sample Hazard Advice Forms and Quarantine Declaration Forms. A completed Sample Hazard Advice Form must accompany every sample shipped to JKTech. In addition, a Quarantine Declaration must be completed for every sample originating from outside Australia.
Key Benefits:
- Key measure of ore grindability
- Ball Mill design and modelling
