Alpine AFG Fluidized Bed Jet Mill

The fluidized bed opposed jet mill: several gas jets intersect at the speed of sound in the centre of a chamber. Powder particles suspended in a fluidized bed become entrained in the gas jets and are accelerated. The particles impact against each other in the focal point of the gas jets and are thus comminuted. Because powder particles collide against powder particles without any mechanical mill components being involved, the product cannot be contaminated by
abrasion. In combination with a high performance air classifier, fluidized bed opposed jet mills achieve extremely fine particle sizes – regardless of the hardness: even diamonds with a value of 10 on the Mohs' scale can be efficiently comminuted. Developed by Hosokawa Alpine while under the name ALPINE AG, the company launched its development onto the market in 1981. Within a very few years, this technology was being applied to a great number of different applications. With this mill, users not only improve the quality of their powders, but are also able to master completely new application fields.
