Liquid starter and drive systems for cement and minerals , They have a high resistance ratio and a very low final resistance at their minimal electrolyte , They are often used for the starting of mills, ventilators, pumps and crushers but also in.
The EPM rotor starter is normally used to control the starting of a slipring motor, , for slipring motors, also named electrolytic starters or Liquid Resistance Starters , for some specific applications (control of the slip for the ball mills for example).
