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

Even though semiautogenous grinding mills and ball mills are normally used in grinding processes the industry is driven to decrease cost by increasing efficiencies and decreasing energy consumption
The product can effectively limit the starting of AC asynchronous motor starting current which can be widely used in fan and water pump conveying type and the compressor load is the traditional star delta conversion autotransformer stepdown buck magnetron device ideal products The ball mill the fire hydrant pump etc Mining
The inrush currents for normal ball mill motors are typically between 40 to 45 per unit of full load current In contrast the inrush current for the high torque motor can be 6 to 8 per unit of full load current In some applications the high inrush can be of great concern especially when we deal with weak power distribution systems
