Benchmarking: Bond - Copper Mountain - SAGMILLING.COM
Changing the effective liner thickness of the SAG mill to 4.5 inch and the ball mills to 3.0 inches results in 1490 t/h throughput prediction (7.1% difference versus the measured throughput). The assumed crushing work index (20) suggests a very competent ore compared to most in British Columbia — this matches comments at the SAG conference.

ball mill grinding test Fine broken jaw
Bond Ball Mill Grindability Test. The Bond Ball Mill Work Index (BBWi) test is carried out in a standardised ball mill with a pre-defined media and ore charge. The Work Index calculated from the testing can be used in the design and analysis of ball mill circuits.
Bond Work Index - an overview | ScienceDirect Topics
Ball mill design requires a Bond work index, BWi, for ball mills at the correct passing size; SAG mill design requires an appropriate SAG test, for example, SPI (Chapter 5 ). Flotation design needs a valid measure of kinetics for each sample, including the maximum attainable recovery and rate constants for each mineral ( Chapter 12 ).
Ball Mills - an overview | ScienceDirect Topics
8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

Bond's Rod Mill For Work Index
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.
GeolabsGlobal | South Africa | Comminution
The Bond Ball Work Index Test determines the resistance of ore to grinding in a ball mill, expressed as a work index kilo Watt-hour per ton (kWh/t). The work index is then used to calculate the specific energy requirements for sizing ball mills or determining their throughput for a target grind. Sample Requirements: 10kg -3.35mm
How to Formulate an Effective Ore Comminution ...
To characterize rock breakage in rod mills, Bond developed a dry lockedcycle test that uses a 12- -in.-diameter, 24-in.-long batch mill with wave liners and running at 46 rpm (see Figure 3 ). The mill is mounted on a rocker, which allows for the mill to be tilted up by 5° to the horizontal and down during the by 5° course of the test.

micrometers in size. According to the Bond standard procedure, the work index is determined by simulating a dry grinding in a closed circuit in the Bond ball mill to achieve 250% circulating load (Bond, 1949, 1952, 1961). The test is performed on a raw material approximately weighing 10 kg, which coarseness is -3.327 mm.
