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 ...
Cleaning and Storing of Ball Mill Charge after the Bond Work Index Procedure is done: Add about 500 g of silica sand into the mill containing the ball charge. Seal the mill. Rotate for 20 revolutions to clean. Empty the mill charge and sand into the ball try once grinding is complete. Clean out the mill using a brush. Put the lid on the mill.
Oct 15, 2015· Bond Work Index (BWI) Hardgrove Grindability Index (HGI) tests for biomass coal. • BWI can predict the potential for mill choking of biomass in a tube and ball mill. • HGI is a poor method of predicting grindability of biomass in vertical spindle mills. • Pellets should be composed of predensified particles close to the target size. •
Safety is a prime consideration for all Alsto equipment and the Bond Index Ball Mill is supplied equipped with acoustic enclosure. The ball mill is designed to accept a ball charge in accordance with F. C Bond''s standard. This ball charge consists of 286 balls as follows: 44 x 35mm balls; 67 x 30mm balls; 10 x balls, 71 x balls and
Ball 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 ).

Coal Mill. Coal mill is a kind of ball mill, which is often used to crush and grind coal bricks into powder, so it is also called coal grinding mill. Coal mill is the main equipment in cement plant, which is used for drying and grinding of coal.
Similar to a Comparative Work Index, this test is an open circuit dry batch grindability test run in the standard Bond Ball Mill for a set time. It can be used at mesh sizes from 65 to 200 mesh (normally 100 mesh). The test requires calibration against the standard Bond Ball Mill Work Index test to estimate the Work Index.
The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index. For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure ), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material ...
Investigation into the applicability of Bond Work Index . The Bond Work Index (BWI or W i) is defined as the calculated specific energy (kW h/t) applied in reducing material of infinite particle size to 80 passing 100 lm 25 . The higher the value for W i the more energy is required to grind a material in a ball mill 10 26 . The BWI test is ...
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.

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.
