Bond Index Ball Mill / Rod Mill BT 100 XL 
The grinding jar for the Bond Index Rod Mill is 12″ x 24″ in size and has a waveshaped design. At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill. The Rod Mill Work Index (RWI) is used for particle size determination in a size range from 25 mm down to 2.1 mm whereas Ball Mill Work

Procedure for determination of ball Bond work
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 scaleup. The test

The standard Bond Rod Mill Work Index test procedure is firstly to stage crush the feed to pass 12.7 mm, and size a representative sample. The test then involves a series of batch grinds in a standard Bond rod mill. A Bond rod mill is 0.305m by 0.610m, with wave liners (of a form described by Bond), which runs at 40rpm and tilts as described below. The charge consists of 8 rods, weighing a

Technical Note Why is the Bond Ball Mill Grindability 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 scaleup. The test has existed for more than 40 years. However, there is little information which explains

Bond Rod Mill Index Test  JKTech
Measuring ore grindability in rod mills. The Bond Rod Mill Work Index is a measure of the resistance of the material to grinding in a rod mill. It can be used to determine the grinding power required for a given throughput of material under rod mill grinding conditions. It is a 'locked cycle' test conducted in closed circuit with a laboratory screen. Sample Requirements: A minimum of 20 kg of

Investigation into the applicability of Bond Work
Bond work index mill behaviour. Fig. 2 shows the mass per size fraction and revolution count for each run of each sample. For wood, miscanthus and sunflower pellets the trend is very similar. The mass size fraction below the target size of 1 mm stabilises quickly to a constant mass, especially for the wood pellets. Even though the revolution count increases from 260 to 2104, the mass produced

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.
