# Bond Ball Mill Work Index Determination

## Bond Work Index Procedure and Method

This Grindability Test or Bond Ball Mill Work Index Procedure is used to determine the Bond Work Index of minus six mesh or finer feed ore samples These equation application methods are used to process <1/2″ ore samples in a Ball Mill using a standard ball charge

## Bond Work Index Formula-Equation

See this useful summary Table of Bond Work Index by Minerals For any circuit, whether a crushing circuit, a rod mill, or a closed ball mill circuit, the Work Index always means the equivalent amount of energy to reduce one ton of the ore from a very large size to 100 um

## Bond Ball Mill Index Test | JKTech

The Bond Ball Mill Work Index is a measure of the resistance of the material to grinding in a ball mill It can be used to determine the grinding power required for a given throughput of material under ball mill grinding conditions It is a 'locked cycle' test conducted in closed circuit with a laboratory screen

## Determination of Bond index of Birnin- Gwari Iron Ore in

Determination of Bond index of Birnin- Gwari Iron Ore in Nigeria K ground using the laboratory ball mill grinding machine 80% passing size for the iron ore marble and granite samples were obtained at 100μm sieve size for the feeds and products The work index of reference minerals; marble and granite were used to calculate the work index of iron ore The value of 2866 Kwh/short ton and

## Work Index Determination for High Pressure Grinding Rolls

cycle test akin to the Bond Ball mill work index determination The first cycle starts with minus 6 mesh ore removed since it is believed that the fines content can fill most of the voids allowing little room for rock breakage and piston movement Without adequate piston movement there is little measurable energy used and therefore very little breakage The test procedure requires that the

## A procedure for rapid determination of the Bond work index

The grindability of an ore in the process of mineral dressing can be determined by use of the Bond work index (W i) This index is determined on a laboratory-scale using a Bond ball-mill and by simulating dry grinding in a closed circuit until the 250% circulating load has been obtained

## JK Bond Ball Mill Test - jktechau

GLOBALLY RELIABLE DETERMINATION OF BOND BALL MILL WORK INDEX JK Bond Ball Mill Test The JKBBM test was developed at the Julius Kruttschnitt Mineral Research Centre (JKMRC) using a database of 1380 original BBMWi results, covering 148 different rock types Relationships between final and cycle parameters examined, showing the procedure gives equivalent results to the BBMWi test …

## Determination of Bond Index of Wasagu Manganese Ore in

Size analysis of the ball mill feed and discharge for both the ores was carried out and 80% passing particle size of the ball mill feed and discharge for the two ores were estimated using semi-logarithm plots The work index of the Wasagu Manganese ore was determined by equating the power consumed in the two indexes of the ore was found to be approximately 1024Kwh/tones which is within the
