For comparing the standard Bond rod-mill work index and the new modeled method, work index (Wi) and produced fine particles in a cycle (Gi) for the four samples determined. The performed paired Student’s t-test results indicated that the Standard Deviation for Gi and Wi obtained by the shortened method are respectively 0.50 and 0.58 in ...
SMC Data Processing. The results from conducting the SMC Test are used to determine the drop-weight index (DWi) which is a measure of the strength of the rock as well as the comminution indices Mia, Mih and Mic. In conjunction with the Bond ball mill work index they can be used to accurately predict the overall specific energy requirements of ...

2019-5-27 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 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.

Mar 31, 2016 The specification for the apparatus to determining a “Bond” rod mill work index is first described in Bond & Maxton (1943). It states that the apparatus is a tumbling rod mill to be operated in a locked cycle test at a fixed circulating load. The geometry of the grinding chamber is described as: mill inside diameter of 12 inches
Bond Ball/Rod Mill Indices ... test in this mill determines the residence time and energy input to achieve a specific size reduction, based on progressive sizing reduction as the material passes through the VXP10. Test results can then be used to determine the operating parameters for
The Bond rod mill work index (RWi) test was conducted according to the standard Bond procedure. The tested Bond rod mill work index is 16.3 kWh/tonne and is considered medium hard. Environmental Tests. The Acid Base Accounting (ABA) and Net Acid Generating (NAG) tests were conducted on flotation tailings (53 micron). The net neutralization ...
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 ...

The Bond Index conforming rod charge consists of: 6 rods of 1.25“ diameter and 21“ length. 2 rods of 1.75“ diameter and 21“ length. The grinding jar for the Bond Index Rod Mill is 12″ x 24″ in size and has a wave-shaped design. At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill.
Bond rod mill work index results from Australian laboratories with smooth liners should not be used in the SAGMILLING.COM models. The test is a 'locked-cycle' test where ground product is removed from test cycles and replaced by fresh feed. The test must achieve a steady-state before completion.
