All MGM rotor configurations at a glance

With six different rotor configurations, MGM Power offers a suitable solution for virtually every application.
Whether you want to screen soil, aerate compost, mix materials or reduce easily breakable products, there is always a rotor that matches your work. Thanks to the Rotor Quick-Change system developed by MGM Power, the different rotors can also be changed quickly and easily.

Rotor configurations for MGM star screening buckets

Screening bucket – Star screen

In addition to the standard rotor configurations, MGM Power also develops and manufactures custom rotor discs. When a specific application requires a different screening fraction, material treatment or rotor configuration, we can develop a custom solution that fully matches your work. This means you are not limited to standard configurations and always have the optimal rotor for your application.

Screening tip:
Screening soil with a screening bucket is most effective when the soil is genuinely suitable for screening.
A useful rule of thumb: if you can work through the soil with a garden fork, it can generally also be screened effectively.

Size reduction tip:
Materials that crumble or break into pieces when struck with a claw hammer can also be effectively reduced using a size reduction rotor in the screening bucket.

Screening shafts

S – Standard Star Rotor

The S rotor is the most versatile rotor in the MGM range and is known as the true all-rounder. Developed for screening soil, sand, compost and recycling materials, while maintaining high capacity even under moist conditions.
Available in 10, 15, 20, 25 and 35 mm.

S style

Functions

  • Screening
  • Mixing
  • De-clodding

Suitable for, among others

  • Soil and topsoil
  • Compost
  • Construction and demolition waste
  • Recycling materials
  • General screening applications

Q – Quality Star Rotor

The Q rotor is developed for applications where the quality of the end product is the main priority. Thanks to the gentle material movement, the structure of the material is preserved and unnecessary size reduction is prevented. Ideal for delicate materials and applications where clean separation is required.
Available in 10, 15, 20, 25 and 35 mm.

Q style

Functions

  • Screening

Suitable for

  • Compost
  • Invasive plants
  • Organic materials
  • Sensitive material streams

Size Reduction/Mixing Rotors (Blocks)

X – Mix Rotor

The X rotor combines screening, mixing, size reduction and aerating in a single operation. The aggressive rotor action breaks down lumps and mixes different materials into a homogeneous blend.
Available in 50 and 75 mm.

X style

Functions

  • Screening
  • Mixing
  • Size reduction
  • Aerating

Suitable for

  • Clay
  • Soil improvement
  • Mixing lime
  • Compost
  • Soil stabilisation
  • Mixing binders
  • Coal handling

B – Block Star Rotor

The B rotor is specially developed for processing moist and organic materials. Thanks to the open rotor construction, throughput remains high even with wet compost, biomass and clay soils.
Available in 40 and 60 mm.

Functions

  • Mixing
  • Size reduction
  • Aerating

Suitable for

  • Clay
  • Compost
  • Biomass
  • Green waste
  • Moist soil
  • Organic residual streams

Size Reduction/Mixing Rotors (Discs)

K – Chopping Star Rotor

The K rotor is developed for aggressively opening, reducing and loosening tough materials. Its aggressive action efficiently breaks down compacted materials and prepares them for further processing.
Available in 10, 15, 20, 25 and 35 mm.

K style

Functions

  • Mixing
  • Size reduction
  • Aerating

Suitable for

  • Turf
  • Compacted materials
  • Compost
  • Filter cake

C – Crush Star Rotor

The C rotor is designed for reducing easily breakable materials during screening. Ideal for glass, ceramics, gypsum, filter cake, digestate and reducing mussel shells, while maintaining a high processing capacity.
Available in 10, 15, 20, 25 and 35 mm.

C style

Functions

  • Screening
  • Mixing
  • Size reduction

Suitable for

  • Mussel shells
  • Glass
  • Ceramics
  • Gypsum
  • Digestate
  • Filter cake
  • Compost
