CR4 - Thread: Suitable Starter for Ball Mill Starting Through ... With a ball mill I would stick to liquid starters, simple and basic! _____ Pessimists are rarely disappointed.
startup of the system. Therefore, liquid resistance starters LRS are commonly used to start up WRIM motors. For liquid starters, the electrolyte solution of Na 2 CO 3 or K 2 CO 3 acts as a resistor, with the resistivity, in turn, depending on the soda concentration. By changing the distance between the upper and lower electrodes,

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
