Fluidized Bed Opposed Jet Mills rely purely on particle-to-particle attrition in the center of a fluidized bed of material; this is achieved by focusing in compressed gas nozzles into the milling chamber which accelerates the particles to produce collisions where energy is released causing particle breakdown.
The Fluidized Bed Opposed Jet Mill AFG from Hosokawa is used for manufacturing powders with a steep particle size distribution and sharp top size limitation in the range < 5 µm to 200 µm; maximum fineness values at maximum product purity. Such particle sizes can only be obtained in connection with an air classifying step. Fluidized bed opposed jet mills are equipped with a dynamic deflector-wheel classifier.
Even difficult products can be processed efficiently with the AFG jet mills. Heat-sensitive materials such as toner, resin, wax, fat, ion exchangers, plant protectors, dyestuffs and pigments; highly pure materials where the requirement is contamination-free processing such as fluorescent powders, silica gel, silica, special metals, ceramic raw materials, pharmaceuticals.
