Special Materials flexible processing
Zemmler double trommel screening machines are suitable not only for soil, waste, or scrap recycling as well as mineral and biomass processing, but also for special and demanding materials.
The decisive advantage lies in the separation of three fractions in just one screening pass—one more than conventional systems. Thanks to the interchangeable wire screen linings, the mesh sizes can be flexibly adjusted, enabling quick material changes and precise processing at any time.
This creates high flexibility for a wide range of applications and material requirements.
