The effect of the mode and top size of applied breakage on ,

break the coal sample to top sizes of 132 mm and 67 mm These sizes were achieved by placing the raw coal particles in a single layer in a steel frame with a specified height to prevent inter-particle breakage The roller was then moved across the frame, crushing the coal to a specific top size

Feb 13, 2017· 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 ,
