The FC Bond Work Index Test Ball Mill was designed by F. C. Bond for use in determining the Bond Index, a measure of grindability and power required for grinding applications. The FC Bond Mills are used in laboratories throughout the world. A copy of Fred C. Bonds Method of Crushing and Grinding for determination of the Bond Index is included with each mill.

the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. Power drawn by ball, semiautogenous and autogenous mills A simplified picture of the mill load is shown in Figure Ad this can be used to establish the essential features of a model for mill
First, a Jar Mill grindability test requires a 5 lb. (2 kg) sample and produces a direct measured specific energy (net Hphr/t) to grind from the design feed size to the required product size. The second test, a Bond Work Index determination, results in a specific energy value
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 stagecrushed to passing size of lt; mm. Any screen size below 600#181;m can be used for the testwork depending on your requirements. Bond Rod Mill Grindability Test
Mill Type Overview. Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75 106 microns.; The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 250 microns.; The CenterPeriphery Discharge mill has feed reporting from both ends and the product discharges
* Bond F. C., Crushing Tests by Pressure and Impact, Trans AIME, Vol 169, 1947, pp 5866. Bond Rod Mill Grindability Test. The test determines the Bond Rod Mill Work Index which is used with Bonds Third Theory of Comminution to calculate net power requirements when sizing ball mills*. Various correction factors may have to be applied.
Ball mill design requires a Bond work index, BWi, for ball mills at the correct passing size; S mill design requires an appropriate S 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
The Bond work index, W i, as an indicator of the grindability of raw materials is not a material constant but rather it changes with change of size of the grinding, in practice we can expect some difficulties and errors when the energy consumption is determined according to this formula in the case when, for a given size of grinding product, the value of the work index W i

Oleg D. Neikov, in Handbook of NonFerrous Metal Powders, 2009. Tumbling Ball Mills. Tumbling ball mills or ball mills are most widely used in both wet and dry systems, in batch and continuous operations, and on a small and large scale.. Grinding elements in ball mills travel at different velocities. Therefore, collision force, direction and kinetic energy between two or more elements vary
