Feasibility Analysis of Frequency-conversion Reform for Driving System of FMC3500 Apron Feeder

In view of the problem existed in hydraulic driving system of FMC3500 apron feeder such as high demands for maintenance technology, complex process and high fault rate, the paper discussed feasibility of reforming hydraulic driving system of FMC3500 apron feeder into frequency-conversion driving system. It introduced main devices and type selection design of frequency-conversion driving system of FMC3500 apron feeder, and made comparison between hydraulic driving system and frequency-conversion driving system from investment cost of devices and operation maintenance. The analysis result showed that the frequency-conversion reform for driving system of FMC3500 apron feeder is feasible, which can improve production efficiency of semi-continuous production system.
