Aug 01, 2005 The Bond work index is one of the most useful and interesting parameters used in designing grinding equipment. However, it must be obtained under restrained conditions, especially in regards to the Bond standard lab mill. The main objective of this study is to show how this index can be obtained using a Denver ball mill, which is present in most mineral processing laboratories.

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. 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 ...

* Bond F. C., “Crushing Tests by Pressure and Impact”, Trans AIME, Vol 169, 1947, pp 58-66. Bond Rod Mill Grindability Test. The test determines the Bond Rod Mill Work Index which is used with Bond’s Third Theory of Comminution to calculate net power requirements when sizing ball mills*. Various correction factors may have to be applied.
When designing concentrating plants, the selection of the technological comminution scheme for beneficiation, the type, quantity and size of the equipment, the determination of optimal grinding regimes and the calculation of equipment loads are
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
However, if the sample is to be prepared by cutting with a diamond saw (cut-core method) as little as 5kg is normally sufficient. Also remember that the products from the SMC Test can be re-used for Bond ball work index testing, the SMC Test being effectively used as a feed preparation step for the Bond ball work index test.
Numerically the work index is the energy required in Kwh/short ton to reduce a given material from theoretically infinite size to 80% passing size of 100 microns (Onemine, 2009). The determination of work index using modified Bond’s method can be compared …
The Bond work index, W i , is defined in a Bond ball mill on the samples of standard size −3.327 + 0 mm. In practice, it is possible to find materials of non-standard size that are finer than 3.327 mm. In this work, a procedure for the calculation of
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. The test requires a minimum of 10kg of sample that has been stage-crushed to 100% passing size of 3.35 mm.
Sep 12, 2019 Many researchers have tried to find alternative methods for determining this Index - to reduce labor costs, sample weight, or to get one without standard equipment. This paper was carried out with the purpose of reviewing, classifying and testing the existing methods for determination the Bond Ball Mill Index.
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).

Bond Ball Mill. This 12” x 12” ball mill is universally used for grindability testing and determination of the Bond Work Index. Mill comes complete with ball charge, and control panel with automatic revolution counter. Titan Process Equipment Ltd. was incorporated in 1999 to provide quality equipment to the process industries.
Jan 01, 2009 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 scale-up.
The work index of a particular material is determined in the laboratory by conducting the standard Bond grindability test. Bond developed separate tests for the rod mill and the ball mill. The simplified test method described in this paper, which is used at Anaconda Research Center to approximate the work index, is an alternative procedure to the ball mill
