PTRF series fine grinding mills reduce mineral products into the ultra-fine range – with one or two rotors.
The feed size is up to 30 mm, depending on the material. Because the PTRF does not crush organic matter, it can be separated optimally afterwards. Use the rotor speed to set the grain size curve and target grain size for your application.
Minerals and foreign matter are cleanly separated from each other.
Impurities and organic matter are not crushed and can easily be separated afterwards.
Lower energy requirement per ton than with conventional machines.
Wear parts are selected specifically for your application.
The single-rotor fine grinding mill crushes minerals to 0–2, 0–1 or 0–0.5 mm. The feed size is up to 30 mm.
The twin-rotor fine grinding mill achieves target products of <0.090, <0.065 and <0.030 mm – as cement substitutes and for foam glass, carbonates and kaolin.

The PTRF crushes only the mineral content. The aluminum is not destroyed and no splinters are produced.
For larger material we recommend the PTH hammer mill.
The PTRF is also used in ASR recycling. The end products are obtained in the fractions 0–1, 1–2 and 2–4 mm.
Research and development, including individual customer trials for your special application.
