The feeding of the jet mill is made by a double valve system connected to a stainless steel hopper.
The jet of the nozzles creates also a fuidised bed which protect the walls of the internal milling chamber and bring the micronized particles up to the dynamic classifier.
By regulating the speed of the dynamic classifier it’s possibile to regulate the outlet particle size basing on the requirements of the customer. If the particles are not enough small, they will be rejected by the speed of the dynamic classifier and they will fall down towards the nozzles.
Once that the particles are enough fine and they’re classified, they go to the cyclone filter which has in his internal a primary filtration system. Here there’s the separation between the powder and the process gas. The powder is collected into a drum under the cyclone filter, the process gas goes into a secondary (HEPA) filtration and then into the athmosphere.
