Spiral Jet Mill

Ideal for dry grinding materials up to a Mohs hardness of 9 Ideal for dry grinding materials up to a Mohs hardness of 9
Suitable for dry grinding of materials with a Mohs hardness < 9, especially those with high hardness, purity, and added-value
Grinding without the aid of grinding media at constant or low temperatures, especially suitable for heat-sensitive materials with a low melting point, sugar, or volatility
Available particle size between D50: 2 - 100 μm
No rotating parts, easy to disassemble and clean
Mill casing is made from one piece of steel plate by CNC processing without welding seams
Easy Cleaning In Place (CIP) & Sterilization In Place (SIP) How it works

The spiral jet mill utilizes compressed air to bring the raw materials into the grinding chamber via a feeding ejector. The high-speed airflow ejected by multiple nozzles propels the raw materials tangentially onto the grinding liner, resulting in friction-based grinding. To control the grinding fineness, you can adjust either the longitudinal depth of the grinding chamber, the pressure, or the feed speed; however, this is not as precise as a fluidized bed jet mill.
