Request an estimateThe ball mill work index laboratory test is conducted by grinding an ore sample prepared to 100% passing 3.36 mm (6 mesh) to product size in the range of 45-150 µm (325-100 mesh), thus determining the ball mill work index (Wi B or BWi). The work index calculations across a narrow size range are conducted using the appropriate laboratory work index determination for the material size of interest, or by …

Dec 14, 2015 · Material Charge (gms)/3.5. Split feed sample to obtain 8 to 12 samples slightly smaller than IPP. Also split out sample for Material Charge. Place Material Charge and Ball Charge in Mill Run x revolutions x = number of revolutions based on estimate of work index; usually 50, 100, 150 or 200 revolutions. Dump Mill, separate balls and Material
The Bond Work Index is determined by a standardized procedure in which the ... namely one in which wet grinding is done in a ball mill of 2,44 m (8 ft) diameter. Read More Alternative Approaches for Determination of Bond Work Index on
The Bond ball mill work index is one of the most commonly used grindability tests in mining, and is often referred to as the Bond work index. The test is a 'locked-cycle' test where ground product is removed from test cycles and replaced by fresh feed. The test much achieve a …
Bond/Barratt Specific Energy Consumption SABC Model. This is a SAG or AG mill plus ball mill model that estimates the overall circuit specific energy consumption using the classical Bond work index equation for multi-stage crushing and single-stage ball milling (E ssbm) including Rowland efficiency factors. The circuit E total is equal to the E ssbm plus an inefficiency factor (CF) related to the difference in grinding …
Module Ball Mill. Minerals pre-crushed to < 3.35 mm and sieved ; Drillcore pre-crushed to < 3.35 mm and sieved ; Half Drillcore pre-crushed to < 3.35 mm and sieved ; The Bond Index conforming ball charge consists of: 43 x 1.45” balls; 67 x 1.17” balls; 10 x 1” balls; 71 x 0.75” balls ; 94 x 0.61” balls; The optimum number of grinding balls is 285. However, the ball diameters vary due to wear. Therefore, the total ball …
The FC Bond Mill was designed by F. C. Bond for use in determining the Bond Ball Mill Index, a measure of grindability and power required to mill various ores. FC Bond Mills are used in laboratories throughout the world. A copy of Fred C. Bond’s Method of Crushing and Grinding for determination of the Bond Index is included with each mill. This Ball Mill can be used continuously or it can be used for any number of …
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 pre-densified particles close to the target size. •
