MTM Trapezium Mill

The MTM Trapezium Mill absorbs the world first-class grinding technology, elaborate design, by our professional R & D team test and improvement, is currently the most advanced grinding equipment.  In order to improve the powder selecting accuracy, it is equipped with a high density of selected impeller powder machine; in order to reduce the vibration and noise, it hosts, powder selecting machine, fan adopts the soft connection; in order to quickly adjust the fineness, it adopts the impeller adjusting device, by changing the selected slot end and shell leaf powder machine between and convenient realization.

Low energy consumption, high yielding and high returns
  • Feed size: :25-35mm
  • Production Capacity: 3-22t/h
  • Materials:Limestone, calcite, dolomite, petroleum coal, gypsum, barite, marble, talc, coal powder, etc.


  • The innovative change of the spring connection structure not only reduces shock of large materials on the aixs and bearing, but also enhances crushing strength of rollers.

  • MTM Grinding Mill consumes less electricity compared to traditional mills. Its electricity consumption is lower than that of ball mill of the same level by over 60%.

  • 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.

Working Principle

Afterbroken materials are evenly sent to the grinding chamber, 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.
