BRT HARTNER STS

BRT HARTNER STS

For Organic Materials Such as Compost, Wood Chips or Bark Mulch

Product Highlights

  • Extremely high throughputs with maximum separation quality
  • Split-Speed system for homogeneous material carpet
  • Separation rates of up to 90% (depending on material)
  • QuickChange system


The BRT HARTNER STS Star Screens are primarily used for biological materials. They are also suitable for applications such as grate ash.
The elasticity of the high-quality plastic star screens allows them to be used even in moist and slightly sticky materials.

Why Split-Speed?

Different operating modes (so-called "recipes") can be programmed according to throughput and material composition. When neighbouring star screen shafts are operated at different speeds, it leads to higher dynamics, significantly greater mixing of the screened material and a considerable increase in the service life of the chains. This results in increased throughput, improved separation quality, optimisation of the self-cleaning effect and a reduction in operating costs.

How Does a Star Screen Work?

Large pieces of material are gradually moved by the rotating screening stars across the screening surface to the discharge point. Fines fall through the gaps between the screening stars and the shafts. The self-cleaning effect significantly reduces operating costs. The screen cut can be adjusted by selecting different screen star sizes and changing the spacing.
