Bond Ball Mill Work Index For Pure Quartz

Bond ball mill work index for pure quartz. 3 STANDARD BOND TESTS The Bonds standard ball mill is used to determine the work index value of differ ent samples The Bond work index is defined as the kilowatthours per short ton required to break from infinite size to a product size of 80 passing 100 m If the breakage.Ball mills usually operate at 65 to 75 of the critical speed. The critical speed is calculated as under [5]. R r g 2 1 n c (2) 2.1.3 Work Index Work index is defined as the gross energy required in kilowatt-hours per ton of feed needed to reduce a very large feed to such a size that 80 of the undersize passes through 100- m screen [5].

Bond Work Index For An Ultrafine Mill

ABSTRACT The study on work index evaluation of Ishiagu galena ore has been carried out. Quartz and Granite obtained from the same location at a distance of 40m apart from lead ore deposit were used to determine the Bond’s work index of the lead ore. The samples were crushed, ground and pulverized using a ball mill.

A Study On Work Index Evaluation Of Ishiagu Galena Ore

A Bond Ball Mill Work Index test is a standard test for determining the ball mill work index of a sample of ore. It was developed by Fred Bond in 1952 and modified in 1961 ( JKMRC CO. 2006 ). This index is widely used in the mineral industry for comparing the resistance of different materials to ball milling for estimating the energy.
