MSizer extend & giant


The new Mogensen MSizer extend and MSizer giant are the most powerful and most flexible long deck classifier machine according to the Sizer principle. The machines combine maximum economic and technical efficiency benefiting from a new screen deck concept with a modified angle of inclination of the screens.


Depending on the specific application, the MSizer extend features two to six screen decks arranged on top of each other, with the topmost screen having the smallest inclination and the bottommost screen having the greatest inclination. In the newly designed compact housing the MSizer screens are actuated with a defined linear swing-amplitude using two vibration motors or exciters. With the precisely designed swing-amplitude the fines quickly flow, almost vertically downwards, while the coarse grains are separated from the material stream with highest efficiency.

Clogging is effectively avoided by means of thin material layers on the screen decks and a significantly increased throughput is achieved. The bigger screen mesh sizes compared to cut point counteract the formation of thick material layers and clogging and lead to a significantly higher throughput and lifetime of the screens.

  • Optimal screening accuracy for excellent process results
  • Highest availability and production reliability
  • Safe and fast screen and motor changes
  • Lower dynamic loads on steel support structure for lower investment costs
  • Reduced energy consumption up to 20%
  • MSizer giant increases the average throughput of up to 35% compared to the MSizer extend, and with it enables reduction or avoidance of parallel machine arrangements within a production plant and decrease in the investment and operating costs.
