Plant

Spiral jet-mills and ultra-fine separators for reproducible fineness down to the low µm range.

Two keys to your powder performance

Spiral jet-mill  PMT Jetmill GmbH

Jet mill

Fine and ultra-fine grinding –
with narrow particle size distribution, energy-efficient, reproducible and scalable
from testing to series production.

Ultrafine separator

Sharp separation curves, high yield even with the finest fractions. For consistent quality and reproducible results in industrial operation.

30% energy savings through Enhanced Energy Utilization EEU SYSTEM

EEU SYSTEM

The thermal energy generated during air compression is unused by cooling in most applications. Together with renowned compressor manufacturer KAESER, a machine has been developed that not only provides hot compressed air, but also maximizes the remaining thermal energy of the compressed air through reduced intercooling.
Enhanced Energy Utilization von PMT Jetmill GmbH
Special nozzles convert this energy, together with that from the air pressure, into even higher jet speeds, resulting in improved energy utilization.
Enhanced Energy Utilization von PMT Jetmill GmbH
Controlled water injection allows the residual thermal energy to be further utilized while also cooling the entire system before internal screening by means of a rotor motor unit, resulting in improved screening conditions.

Precision & efficiency up to 190 m/s

Rotor motor unit

The rotor motor unit, manufactured with the highest precision, is integrated directly into the grinding chamber and is largely responsible for the reliability and low energy consumption of PMT spiral jet mills and fine separators.
Image section of the rotor motor-unit at Jetmill GmbH
Extensive aerodynamic research led to the patented shape of the rotor discs and, together with a perfectly matched mechanical concept, enables circumferential speeds of up to 190 m/s to be achieved.

These high circumferential speeds enable the grinding or classification of products with a maximum grain size of less than 1 μm (at large-scale throughput rates and high content yield when used in classification plants).

The rotor is built on a high-speed motor developed in-house with a special maintenance-free bearing system.

Fully automatic process control

The PMT system control enables centralized, fully automatic process control via HMI panel and PLC system. Raw material feeding is regulated depending on the load via the rotor current consumption as a measure of the loading density in the grinding chamber, preventing overloading and stabilizing the top cut for consistent final grain sizes. We can optionally integrate remote access and complete data acquisition of all core parameters for real-time monitoring, trend analysis, and reliable reproducibility.

Maintenance

The professional maintenance of the rotor-motor unit by PMT-Jetmill enables constant production of high-quality grinding products.

The modular rotor-motor unit is completely disassembled, cleaned and reassembled with new high-performance bearings during a service. Individual rotor discs are replaced or reused depending on the degree of wear.
