Laboratory Spiral Jet Mill

Compressed air or superheated steam or other inert atmosphere enters the gas distribution pipe from the feed gas injection port. Under the action of its own pressure, the gas passes through several nozzles arranged tangentially around the seat ring to generate high-speed jets and collides with the materials entering the grinding chamber. The feeding injector composed of hopper, feeding nozzle and Venturi tube is used as the feeding device. The material in the hopper is ejected to the Venturi tube by the jet stream from the feeding nozzle. In the Venturi tube, the material and the air flow are mixed and pressurized and enter the crushing chamber. The crushed material is brought to the center group tube by the air flow and passes through The stack pipes go axially into the center exhaust pipe up or down into the collection unit.
