Gentle Preparation by High-Quality Star Screen Technology

Fine over Coarse

The 3F star screen semi-trailer achieves top performances in soil restoration, preparation of biomass and recycling of various waste materials from house, garden and industry. The low fuel consumption saves costs that can be invested in other projects. The 3F star screen semi-trailer screens fines before remaining materials to ensure energy-preserving and therefore environmentally-compatible efficiency.


A Long-Term Partnership
High-Performance Machine with Low Demands

In spite of its high performance, the 3F star screen semi-trailer is easy to operate and characterised by high maintenance compatibility and low risk of wear. A single screen machine can be used safely and without interferences for large-area preparation over a long period of time.

The short equipment times for the semi-trailer are of benefit as well. They save a lot of effort. The discharge belts of the machine have a comfortable output height and length for the highest possible material cones. The grain size can be adjusted within seconds by speed adjustment of the screen shafts.

  • Quick-changing screen decks
  • Modular build
  • High throughput
  • Separation into up to 4 fractions with tipping/vibrating grate or wind shifter
  • Motor management-system

In the right tracks
Dosage Screw

The dosage screw convinces as a compact, user-compatible dosage technology for the mobile star screen and alternative screen machines.

Applied protection
Tipping Grate

Placed above the feed hopper, the hydraulic tipping grate effectively separates large rocks, mechanical scrap and other coarse irritants.

Technical benefit
Remote Control

The radio remote control adds mobility to the screen technology while reducing the time and personnel needs on site.

Simple expansion
Volume Enlargement for Hoppers

The volume enlargement by attachment is a comfortable option to increase the feed hopper capacity. It can be used on semi-trailers and caterpillars.

Blowing away irritants
Wind Shifter for Residual Material

The wind shifter serves to separate very light-weight plastic or paper materials that can become irritants, e.g. in biomass processing.

Sensible retention
Manually adjustable retention plate in the hopper

The retention plate installed in the hopper can be adjusted easily and prevents the screen material from falling onto the screen deck of the support unplanned.
