MISU mobile screening technology acts as a filtration system that screens different forms of material using the patented Multiple Spinning Rotor System. These rotors allow smaller particles to fall through, while holding back larger debris. The rotors will also mix and crush softer materials.

The action is one of each rotor ‘floating’ in position as it spins finding its own centre of gravity. The normal two-way operation of the rotors frees debris that can collect on the blades.

This is what makes MISU unique...


MISU produces a number of screening attachments that save time, money and material, while being an adaptable tool for use across a wide range of machines, from skidsteers and backhoes to wheel loaders and excavators.

We pride ourselves on:

  • Heavy duty construction
  • Low maintenance
  • High performance
  • Screening range from 20mm through to 80mm
  • Mixing and crushing of soft materials
  • The elimination of multi handling, meaning you can get more done in less time
  • MISU is fully mobile and easily transportable
