  • Ball Mills vs Rod Mills

    The rods, being only 35 inches long, may be regarded as much more rigid than rods regularly used These observations should be compared with table 4, which shows that the heavier stuffed pipes did more selective grinding than the light pipes There the diameters were the same, and unquestionably selective grinding was due to the greater weightWorking 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 theBall Mills Mineral Processing & MetallurgyDec 17, 2019· At present, the most widely used grinding equipment in the dressing plant is ball mill and rod mill As far as the working principle is concerned, both ball mill and rod millare the same The grinding medium (steel ball or steel rod) installed inWhat is the difference between the ball mill and rod mill
