A fine way to mill material

Published: 20 December 2011 - Michelle Lea

A dry agitating bead mill for the efficient milling of sub-micron sized particles has been introduced by Hosokawa Micron. The Micron Pulvis is said to be capable of producing finer particle sizes than a jet mill with energy consumption typically 80% less than other mills.

The mill is located at the bottom of the machine and ground particles are conveyed by air, passing through the grinding chamber to the integrated classifier, the operating speed of which determines the fineness of the end product. The classifier separates the required fine product from coarse particles, and these particles are then returned to the grinding zone.

With the option of ceramic, wear protected grinding and classifying parts, the unit is suitable for milling ceramic materials, metal oxides, battery materials, minerals, glass, hydrogen absorbent alloys, magnetic materials, pigments and carbon.

The machine is designed for easy access, disassembly and cleaning and can be used in multiple applications and tasks involving frequent material changes. Available in sizes from 0.75kW grinding motor (1.00kW classifying motor) to 70.0kW grinding motor (30.0kW classifying motor), the Pulvis is suitable for test purposes through to scaled up production.
