Con-E-Co Company offers a Intelli-Drive Variable Frequency Drive (VFD) system that monitors a batch plant’s activity and decelerates the drum’s rotation between batches or when mix time has been exceeded. The result is increased component life, reduced maintenance costs, less spatter (and clean up time) and optimized discharge speed. With the Intelli-Drive VFD, when in a reduced speed mode between batches, less stress is placed on components such as the rollers, roller track, pinion gears and ring gears. The Intelli-Drive VFD system also lessens wear on items such as the drum liners and paddle liners. When the Process Logic Controller (PLC) senses the drum being loaded, it speeds the mixer back up to the ideal mixing speed. Once the mixer begins tilting for discharge, the PLC again slows the mixer’s rotation.
