MTW Trapezium Grinding Mill

Lower operational & maintenance costs, excellent environmental protection

MTW Trapezium Grinding Mill is developed by our company’s experts based on 10 years’ R&D on grinding machines. It owns many independent patents, such as overall prick gear drive, internal thin oil lubrication system, arc-shaped air duct. All of these make it lead the trend of the milling industry in the world.

Materials:Limestone, calcite, dolomite, petroleum coal, gypsum, barite, marble, talc, coal powder, etc.

Product Advantages

  • The split shovel blade enlarges working area a lot. Besides, the unique pneumatic sealing device effectively avoids spill-over of coarse powder.
  • The structure is more compact, occupying smaller floor area. Meanwhile, equipped with professional dust remover, the operation is quite friendly to the surrounding environment.
  • Compared with traditional straight air ducts, the inlet of this air duct is smooth with little resistance and the outlet is easy for the dispersing of materials.
  • The grinding rollers and rings are made of wear-resistant alloy. Their service life is expected to be 1.7-2.5 times longer than traditional rollers and rings.

Working Principle of MTW Trapezium Grinding Mill

After broken materials are evenly sent to the grinding chamber of MTW Trapezium Grinding Mill,some materials are blown away by airflow to the powder concentrator for classification. Under the action of the impeller of powder selector, materials which fail to meet fineness would be sent back to grinding chamber to get another grinding while qualified powders would be collected by cyclone powder collector and discharged from the bottom as finished products. And, after that, the airflow would go into the fan along with the air return duct at the top of cyclone power collector.
