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 mm whereas Ball Mill Work Index (BWI) is used for the range from mm down to 100 µm. Adjustment of grinding parameters:

Bond Ball Mill Grindability Test. The test determines the Bond Ball Mill Work Index which is used with Bond''s Third Theory of Comminution to calculate net power requirements*. Various correction factors may have to be applied. W = Wi (10/√P – 10/√F) Where W = Net power consumption in kWh/t

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 mm, as required for the Bond Ball Mill Work Index test feed.

The work index (Wi) is calculated in a laboratoryscale ball mill with Bond equation. The Bond work index has been widely used in designing fullscale mills but the Bond test is rather complex, lengthy susceptible to procedural errors and this is why attempts have been made to abbreviate and simplify Bond test procedure (Weiss, 1985). 2.

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical
WhatsAppعرض المزيدBall 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 ).
