Design and function principle of a PMT spiral jet mill

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.

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. Using functional

Functional filler demand special grinding technologies. Every day we experience an increasing technical demand from the filler industry. We respond to the change from ‘extender filler’ to ‘functional filler’ with the PMT spiral Jetmill. High classifier speed and special classifier geometry allow products with a fineness in the low micrometer range and, depending on the material, even below 1 µm. + Finest particle sizes (d50) + Exact top cut (d97) + Narrow particle size distribution + High aspect ratio + Improvement of functional properties + Up to 30 % less energy consumption with newest development + High grinding efficiency due to the closed grinding and classifying circuit + Easy adjustment of fineness by regulation of rotor speed + Possibility to remove impurities + Guaranteed operational reliability

In our toll grinding center in Kammern, Austria we provide toll processing of minerals, including fine grinding, classifying, re-packaging, etc. > Extension of product range > Bridge production bottlenecks > Highest product quality > Exact overview of costs > No investment costs > No operating costs > Calculable market launch of new products > High flexibility
