Ultra-fine grinding jet mill for coarse and fibrous materials
Effortlessly achieve ultra-fine particle sizes in coarse and fibrous materials without pre-crushing, enhancing your production line’s efficiency and maintaining product integrity. Perfect for industries needing precise grinding solutions.

The Alpine Microburst AMB Spiral Jet Mill from Hosokawa Alpine is designed for ultra-fine grinding of coarse and fibrous materials without the need for pre-crushing, distinguishing itself with a large, central inlet ideal for diverse applications such as functional food, cosmetics, and pharmaceuticals. The mill efficiently processes materials like cellulose and cannabis into powders and granules, leveraging its customizable grinding chamber and modular design. It operates continuously and at high speed, integrating seamlessly into production lines with a user-friendly, PLC-controlled system. Optional ceramic components ensure high wear protection, and the machine’s hygienic, stainless steel design meets GMP standards, supporting quick cleaning and low-maintenance operations. Configurations include stand-alone baseline versions to economically accommodate varied operational needs.
