Liquid Resistance Starters GINO-AKA

Therefore, liquid resistance starters LRS are commonly used to start up WRIM motors. For liquid starters, the electrolyte solution of Na2CO3 or K2CO3 acts as a resistor, with the resistivity, in turn, depending on the soda concentration. By changing the distance between the upper and lower electrodes, the resistance is reduced smoothly.

The starting point for ball mill media and liquid charging is generally as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 45% to 50% above the ball charge for total of 58% ...

This is because if the solid-to-liquid ratio is too low, the slurry of the ball mill will be too thin which limits the effective use of the energy supplied to operate the mill. Conversely, a higher solid-to-liquid ratio results in a highly viscous slurry that restricts the movement of the balls and reduces the grinding efficiency.
