My company used Fest powdered coal rotor scale, kiln, kiln tail models were DRW4.10 and DRW4.12, the production line has been put into operation since 2011, there have been many times the rotor can not scale coal under the situation, the parties to find reasons , Mainly caused by the blockage of the rotor balance and the failure of the rotor scale dust collection system. 1 blocked the next tube 1.1 failure performance under the tube and clogged with excessive moisture and foreign body stuck. Most of the material in the lower tube and scale body connected to the location, here is the transition zone between the cutting tube and the rotor, if large pieces of material, easy to plug. The specific phenomenon is:
