MTW Trapezium Grinding Mill Main Features and Benefits

  1. The bevel gear transmits in a whole, which makes the structure more compact, installation and commission more convenient.
  2. Our MTW European Trapezium Grinding Mill equiped the internal oil pump,which can lubricate the bearings both in main shaft and bevel gear shaft, without connecting any external oil pump or lubrication station.
  3. Our MTW European Trapezium Grinding Mill uses curved wind tunnel repalcing former straight one in the traditional mill.
  4. Sheet of the shovel is easy for change, and cyclone collector in isloted type.
  5. Porthole adopts smooth wind spiral, which also gives the grinding mill a very beautiful appearance.
  6. bevel gear integral transmission: The traditional grinding mill needs decelerator and ratcheting to drive the main shaft that increase the centering difficulty and is easy to bring noise as well as reduce the efficiency. MTW series mills adopt bevel gear integral transmission that compact the whole structure and simplify the installation as well as improve the efficiency.

MTW Trapezium Grinding Mill working principle

The main shaft of MTW European Trapezium Grinding Mill connected with the the roller hanger in the top. It is drived by the bevel gear which trabsmits in a whole.The rollers of the grinding mill rotate not just around the main shaft, but also around the grinding ring. Also, rollers can rotate to itself because of friction.Shovels are installed at the bottom end of hanger; materials will be fed into space between rollers and ring to form a material layer when shovels rotate together with rollers. Then air classifier drives the blades in the rotary table through the speed motor to classify the powder.
