PMT Powder Maker Group GmbH is one of the leading companies regarding dry grinding and classifying for ultra-fine particle sizes.

At the toll grinding center in Kammern/Austria PMT Powder Processing GmbH offers the possiblity to grind and classify soft to middle hard minerals, chemical and natural products.

To meet the industry’s need for high aspect ratios at extremely fine particle sizes, PMT developed the PMT spiral jetmill - in order to micronize materials down to particle sizes below 1 micron top cut.

Functional fillers with energy efficient jet mill EEU-System reduces specific energy consumption of dry ultrafine grinding.
Functional fillers with energy efficient jet mill
EEU-System reduces specific energy consumption of dry ultrafine grinding. Today functional fillers are confronted with steadily increasing requirements. Applications, e.g., in in polymer industry, used to be satisfied with extender fillers, which cheapened the compound. During the last decade the material profile has changed from pure volume filler to functional additives and fillers. But that is not good enough by half. Striving for sustainable ways of production and low carbon footprint begins in raw material processing and sets new standards. Modern spiral jet mills are the state of the art in the micronization of highly lamellar fillers. With their specific type of comminution based on shear forces, the particle shape significant for the downstream applications - whether in flake or needle form - can be preserved or even improved. With the development of the EEU (Enhanced Energy Utilization) system, the proven PMT spiral jet mill could be improved substantially in order to meet the ecological responsibility as well.

Ultra-fine grinding meets Italy - PMT at SOLIDS Parma 2023 We invite you to visit us at SOLIDS Parma 2023 to learn more about energy efficient fine grinding and our toll grinding service close to the Italian border.
Ultra-fine grinding meets Italy - PMT at SOLIDS Parma 2023
We invite you to visit us at SOLIDS Parma 2023 to learn more about energy efficient fine grinding and our toll grinding service close to the Italian border. PMT Powder Processing and PMT-Jetmill are exhibitors at SOLIDS Parma 2023, the European Trade Show for Granules, Powders and Bulk Solids Technologies. On June, 14th and 15th we present our newest developments in ultra-fine grinding and classifying. We would appreciate welcoming you at our booth B15 in Hall 8 and inform you about energy-efficient grinding and toll grinding. Machines and toll grinding PMT produces jetmills for dry fine grinding. We sell machines, and we offer toll grinding as well. That happens in our toll grinding center in Kammern/Austria, close to the Italian boarder, where we grind your raw material according to your requirements. Possible product fineness is in a range between 1 micron up to about 50 micron. Spiral Jetmill The mill type is a spiral Jetmill. It provides very smooth grinding and excellent delamination. Is has an integrated classifier and with that it is possible to produce a very fine product with an exact top cut and narrow

Highest fineness through circumferential speed up to 190 m/s The Spiral Type Jetmill of PMT-Jetmill is specialized in optimizing air streams in combination with a so-called rotor-motor-unit.
Highest fineness through circumferential speed up to 190 m/s
The Spiral Type Jetmill of PMT-Jetmill is specialized in optimizing air streams in combination with a so-called rotor-motor-unit. This combined “rotor-motor-unit” (RMU), built with the highest precision, is the heart of the PMT spiral jetmill. It grants a high operating security, low energy consumption and finest products of PMT’s Jetmills. The results from aerodynamic research work were implemented into a patented rotor wheel geometry and in a mechanical concept to achieve circumferential speeds of up to 190 m/s. When used in jetmills with internal fine grinding and classifying circuit, products with a fineness even below 1 µm top cut can be produced. This fineness can be achieved even in industrial scale machines and high content recovery classifiers. The rotor unit is directly combined with a high-speed motor unit with the advantage of maintenance-free high-speed bearings.

Ultra-fine grinding of Kaolin
Spiral jetmills enable ultra-fine products with dry processing. The Spiral Type Jetmill of PMT-Jetmill is specialized in optimizing air streams to improve efficiencies and to minimize energy consumption. One application example is Kaolin. The material is fed pneumatically to the spiral jetmill and runs spirally through the milling chamber. Grinding media enters the area through the milling nozzles. Grinding media is either compressed air (3.5 to 15 bar and 240°C) or superheated steam (up to 24 bar and 400°C). The air stream fluidizes the material-bed and lifts as much particles as possible into the stream. Comminution is mainly based on shearing forces which result from velocity differences. The integrated dynamic classifier is capable to run at a maximum circumferential speed of 190 m/s. As soon as the particles reach a certain fineness, they can pass the classifier to the final product. The fineness can be easily adjusted by variation of the classifier speed. One application example is Kaolin: Sample 1: * 9700 rpm classifier speed * Particle size: d50 = 2,0 µm (after Sympatec Helos) * Particle size: d97 = 5,2 µm (after Sympatec Helos) Sample 2: * 7700 rpm classifier speed * Particle
