Dear all, kindly suggest for a suitable starter to start a ball mill with 2600 kw, 1000 rpm, 11 kv slipring induction motor. has any latest technology invented to start the motor other than LRS & FCMA. can the VVFD solution fullfil the initial torque compansation. the GD2 value of mill is around 400 kg m2.
DetailsAOIP starters for slipring motors, also named electrolytic starters or Liquid Resistance Starters (LRS), use mobile electrolytic resistances. Each starter is made of 3 tanks (one per phase) filled with conductive liquid named electrolyte (water mixed with salt, usually Sodium Carbonate) and two immerged electrodes.
DetailsTherefore, liquid resistance starters LRS are commonly used to start up WRIM motors. For liquid starters, the electrolyte solution of Na 2 CO 3 or K 2 CO 3 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.
DetailsThe motor drives a cement ball mill, and the operator is blaming the starter but I think that if it is not accelerating as it used to then the load has increased. Any thoughts? Also the starter used soda ash (sodium carbonate) to modify the conductivity fo the water, does any one know what the chemistry of the liquid should be?
