Active Front-End Converter with AC drive

摘要

Mixers of raw materials are transported mostly through conveyor from one place to another place. In cement industries this distance could be in kilometres and possibly from elevated position to ground level. Continuous flow of raw material mixers is very important for productivity. Whiletransporting from elevated position (inclined) it is very important to brake the conveyor speed otherwise excessive speed can occur during mass transport. This excessive speed can cause damage to mechanism of conveyor.
