The Roller Speed Control of High Voltage Electrostatic Separator Based on PLC

Abstract:

The main aim of this paper is improve the high voltage electrostatic separation efficiency of roll-type electrostatic separator. To this end, a method of controlling the roller to obtain the best rotate speed was introduced. Experiments of system design were performed on 315-2DP type Programmable Logic Controller (PLC) produced by Siemens, E6B2 - CWZ6C encoder provided by Omron and MM440 converter obtained from Siemens. According to the nature differences of the separation particles, presetting the roller rotation speed in the upper machine. Then it is downloaded to the PLC. Through the tail encoder of the motor to receive the signals, calculating the roller speed and feedback to the PLC to control the converter, then formed a closed-loop control system of the motor speed.
