Ultra-fine grinding of coarse materials without pre-crushing
Hosokawa Alpine AG has developed a new jet mill where coarser products can also be added without pre-crushing. The company named the spiral jet mill Alpine Microburst (AMB) after a weather phenomenon. "The falling downdraughts in a microburst are reflected in the central material feed of the mill and high energy input to a clearly limited area," explains Hermann Schmidt, Operations Director Pharma & Lab Division at Hosokawa Alpine AG. Even fibrous products, which previously could only be crushed with great effort or hardly at all, can now be finely milled with the AMB.

With the AMB spiral jet mill, the company is now presenting its customers with a valuable addition alongside its AS spiral jet mill and the AFG fluidised bed opposed jet mill. In contrast to traditional spiral jet mills, its large, central inlet allows more coarsely ground products to be processed directly. Up to now, this required pre-crushing. While the AFG is an ideal solution for a steep particle size distribution, the AMB offers a compact solution with lower investment costs and a simple process.New opportunities for a range of future industries
"With our AMB spiral jet mill, manufacturers of functional food or finely ground food products, for example, will have access to an optimised solution in the future," says Jürgen Zeller, Sales Manager Food Division at Hosokawa Alpine. Scientific studies have shown that fine milling in the production of functional food leads to better extractability, solubility, mouthfeel and bioactivity. The spiral jet mill also opens up completely new possibilities for processors of cannabis, fibrous products, cellulose or PLA/PLGA biopolymers.
Monobloc design and hygienic design

For greater flexibility and efficiency, the grinding chamber of the AMB can be adjusted to the properties of the material to be milled. The new spiral jet mill, which can be equipped with optional wear protection, is available from Hosokawa Alpine in the sizes 100, 200 and 315. "The machine largely corresponds to our AS series in terms of sizes and peripherals. Other important aspects include the monobloc design and our hygienic design, both of which have been proven many times over," explains Hermann Schmidt. The well thought-out design and use of clamp fittings ensure fast and straightforward disassembly and make cleaning quick and tidy. The concept is further enhanced by the simple explosion protection system, easy handling and modular machine design.
The new jet mill also comes in a standardised baseline variant. This can be used independently and facilitates semi-automated and economical production. The baseline concept implements the points mentioned above in a simple and compact design and offers an impressive user-friendly and intuitive operation. In the completely ready-to-use system with ergonomic design, all of the control elements are combined in one console.
