MTW Trapezium Mill Detail Info

• MTW Trapezium Mill application

  MTW European Trapezium Grinding Mill is mainly applied to the powder processing of mineral products in industries of metallurgy, construction, chemistry, and mining etc. It can produce powder from non-flammable and non-explosive mineral materials， such as barite, limestone, quartz, calcite, granite, porcelain clay, basalt, gypsum etc.

• MTW Trapezium Mill main features and benefits

  • 1. This series grinding machine is vertical structure.
  • 2. Takes small area.
  • 3. Strong whole-set.
  • 4. Moreover the main unit transmission device uses the airtight gear box, and the transmission is steady.
  • 5. The important part of grinding machine uses high quality steel, therefore complete machine is durable and reliable.
  • 6. The mill electric system uses centralized control, advanced and reasonable shape, high automaticity, small and light vibrating feeder, easy to adjust and energy saved.

• MTW Trapezium Mill Working Principle

  The main shaft of this grinding machine connected with the roller hanger in the top. It is drived by the bevel gear which transmits 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 The classifier drives the blades in the rotary table through the speed motor to classify the powder.
