Application of Frequency Converter Driver in Long Belt Conveyor
With the frequency converter for driving belt conveyor, the synchronous control of torque and speed for the belt-drive unit can be achieved and the start-up characteristics of belt conveyor can also be improved. This paper uses two methods for achieving synchronous drive of belt conveyor, one is synchronization through master-slave control of frequency converter itself, the second is adding external algorithm implemented by PLC systems. This article describes a variable-frequency adjustable-speed drive system used for long distance belt conveyor in mine main inclined shaft or ground. This frequency conversion device and system can be applied to the adjustable-speed drive process of constant torque load for conveyor.
