Mill drives Large drives such as grain or cement­mills often still use slipring rotor motors. } Solution: Employing a frequency monitor to control the ramp-up. } Advantage: A soft start of the working equipment pre­ serves the mechanical drive elements and prevents current peaks in the feeding mains. Fan drives Fans and blowers are often driven via V-belts. A torn V-belt or clogging of the filter interrupts the continuous flow of the delivery medium. } Solution: Monitoring for underload with cos guard. } Advantage: Dispensing with external sensors, e.g. pres­ sure transmitters. Quick...
