Jet Milling is a concept of feeding powder particles into a flat circular milling chamber and subjecting the same tangentially with pressurized air or nitrogen through a venturi. The Powder Particles are accelerated in a spiral movement inside the milling chamber by a number of angular holes in a ring and placed around the periphery of the chamber.

Spiral Jet Mill A spiral Jet Mill is also called a pancake jet mill. The spiral jet mill is suitable for the fine and ultrafine size reduction of materials up to a Mohs hardness of 3 that display brittle crystalline grinding characteristics. They are typically used in applications where a high ultrafine portion is required.

Spiral Jet Mills. Most of the spiral jet mills currently on the market still have the original flat rectangular shape dating back to the 40's that creates turbulences (therefore caking problems) and do not allow laminar jet streams. Some mills still have the original lateral tangential product entry, with blowback problems, asymmetrical ...

Spiral jet mill is a horizontal oriented jet mill with tangential grinding nozzles located around the peripheral wall of the grinding chamber. Materials are speeded up through venturi nozzles by a high-speed fluid discharged by pusher nozzle and enter into a milling zone.

A jet mill grinds materials by using a high speed jet of compressed air or inert gas to impact particles into each other. Jet mills can be designed to output particles below a certain size while continuing to mill particles above that size, resulting in a narrow size distribution of the resulting product. Particles leaving the mill can be separated from the gas stream by cyclonic separation.
