MQL fluidized bed air mill equipment is a kind of compressed air refrigeration, filtration after drying using the nozzle formed supersonic air accurately shot into the crushing chamber, under the action of the air can make the material show a fluid state, and accelerated motion processing accelerated materials will be at the intersection of the jet stream of multiple nozzles to meet. After the material is merged, it will collide with each other because of the action of high-speed air flow, and then friction will be continuously crushed, and after recycling treatment, it will achieve the role of ultra-fine grinding.
