Thankfully the performance of the vertical mill was still better than the ball mills which reinforces the use of this technology. Design parameters of vertical roller mill and the cut size increased from 29 to 35 pm (survey 1). Finally the ball mill model was developed on a component basis and the r/d values were found

Bond Work Indexan overview ScienceDirect Topics

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 ). Working Principle Operation. The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill for example a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x 5′ where the
