SAG mill, Ball mill, Locked charge, drop charge, frozen charge, Liquid Resistance Starter, LRS INTRODUCTION A "locked charge incident" is referred to by Svalbonas (2002) as a "drop charge," while Vanderbeek (2004) refers to "locked charge protection" and Frank (1997) refers to "frozen charge
Liquid resistance starter current. The two graphs below are the instantaneous and root mean square current measured in a conductor of a liquid resistance starter for an electric motor of a ball mill. These currents are used to confirm the condition of the liquid in the liquid resistance starter and to do root cause assessment if there are problems.
The Vectrohm electrolytic starter, also known as a liquid resistance starter (Liquid Resistance Starter or Liquid Cooled Starter), provides the ring motor with starting power. Our technical process: The variation in the height of the liquid in the tank, where the fixed electrodes are placed, varies the ohmic value of the rotor.
