Research on Selection of Coal Unloading Equipment Under Tippler

  Introduction  The tippler is a common coal unloading equipment used in railway coal project. The coal unloading equipment under the tippler should be selected based on comprehensive consideration of the system layout, civil conditions and investment.

  Method  Comparative analysis of common coal unloading equipment was carried out on the basis of analyzing the working principles and technical characteristics of different common coal unloading equipment.

  Result  The results show that activation coal feeder has certain advantages in the coal unloading equipment selection under tippler for its unique capability of preventing disheveled coal and slip coal, self-locking ability and good environmental protection performance. With the good environmental protection performance, low operation and maintenance cost and flexible arrangement, the fully enclosed screw-type coal feeder also has certain advantages.

  Conclusion  Both the activation coal feeder with good comprehensive performance and the fully enclosed screw-type coal feeder are applicable when the coal unloading equipment under the tippler is arranged in line. It is recommended to use the fully enclosed screw-type coal feeder as a preference when the coal unloading equipment under the tippler is arranged vertically.
