resistance starter ball mills

Liquid starter

Jul 31, 20032. Although this is a moving electrode starter, the resistance (and performance) can change from start to start. More advanced moving electrode starters incorporate a heat exchanger to ensure the electrole solution remains at a fixed temperature and therefore the only item influencing resistance is the position of the electrodes. Hope this helps

Electrolytic starter (LRS) for high power slipring motors

The starter slowly decreases the resistance, ensuring a progressive starting of the driven machine, unlike step starting due to starters with fixed electrodes. At the end of the starting process, the resistance is short-circuited. (control of the slip for the ball mills for example). Why using a starter

Liquid

Therefore, Liquid Resistance Starters ( LRS) are commonly used to start up WRIM motors in industrial environments. For liquid starters, the electrolyte solution of Na 2 CO 3 acts as resistor, which in turn depends on the soda concentration. By changing the distance between upper and lower electrodes, the resistance is reduced smoothly.
