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.

Ball milling as an important pretreatment technique in ...
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.
