Alpine Microburst AMB

The new spiral jet mill Alpine Microburst (AMB) is a practical addition to our proven AS spiral jet mills and AFG fluidised bed opposed jet mills. This is because it can also be used to finely grind coarser and fibrous products without the need for pre-crushing. The large, central inlet now allows coarser ground material to be processed directly.

The AMB is our low-investment compact solution in the sizes 100, 200 and 315.

What makes the Microburst so unique?

  • Ultra-fine grinding of coarse and fibrous materials without preliminary crushing
  • Large, central material infeed from top to bottom
  • Grinding chamber can be flexibly adapted to the properties of the material to be ground
  • Fast cleaning and straightforward disassembly thanks to clamp fittings
  • Modular machine design and simple Ex concept
  • High wear protection due to ceramic components (optional)
  • Also available in a stand-alone baseline version

Why Microburst?

Spectacular weather phenomenon as an innovative new machine

We named the Alpine Microburst (AMB) spiral jet mill after a well-known weather phenomenon. The falling downdraughts in a microburst are reflected in the central top-to-bottom material feed of the mill and high energy input to a clearly limited area.

AMB jet mill for coarse & fibrous materials

High-quality powder production - without high-cost pre-crushing

Want to feed in coarse and fibrous materials without pre-crushing? The new AMB jet mill makes it possible.
Its large, central inlet allows more coarsely ground product to be processed directly. It is fed in centrally from top to bottom. The feed tube also allows very coarse and fibrous materials to be fed in, which previously could only be achieved through a complex and high-cost pre-crushing process. The grinding chamber can be ideally adapted to the properties of the material to be comminuted. The machine largely corresponds to our AS series in terms of sizes and peripherals. The monobloc design and hygienic design are already proven solutions in other applications. The well thought-out design and use of clamp fittings ensure fast and easy disassembly and make cleaning quick and tidy. The concept is further enhanced by the simple Ex-concept, user-friendly handling and modular machine design.

Scope of application

Functional food

Finely ground foods


Functional food:
Manufacturers of functional food can rely on an optimised solution with the new AMB jet mill. Scientific studies have shown that fine milling in the production of functional food leads to better extractability, solubility, mouthfeel and bioactivity. This is the case, for example, when it comes to fine milling black or green tea.

Finely ground foods:
Use of the new AMB spiral jet mill lends itself perfectly to the 'all natural' products trend, where natural flavours and colours are used in the final products. The AMB can be profitably applied wherever a production process has been limited in the past by the injector size of conventional spiral jet mills.


Medical PLA or PLGA manufactured granulates as a carrier matrix can now be finely ground with the new AMB.


Additional applications:
In principle, the AMB can replace a conventional spiral jet mill wherever the grinding process has so far obstructed or limited the injector. This also includes processing materials such as

  • Cellulose
  • Cosmetics
  • Pigments and waxes in the form of flakes, pills and granules
  • Cannabis

  • Horizontal mill housing for handling
  • Special grinding chamber geometry for a wide product range
  • Grinding chamber without rotating fittings
  • Material infeed via large feed tube
  • Exchangeable nozzle ring with Laval nozzles
  • Stainless steel design, product-contact surfaces with a high quality of finish (according to order)
  • Easy to dismantle and clean
Product Final fineness
Limestone (1 - 2 mm) 97 % < 12 µm
Black tea (10 - 15 mm) 97 % < 28 µm
Oat flakes (5 - 7 mm) 97 % < 60 µm
Dried fruit ( 1 - 3 mm) 97 % < 30 µm

Also available as baseline version

All configuration options at a glance

With the AMB spiral jet mill, we are not only presenting you with customised production systems for challenging customer requirements, but also a standard 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.
