Hosokawa Alpine AFG 140

Fully refurbished Hosokawa Alpine AFG 140 used system by Alpine Originals.

The Hosokawa Alpine AFG fluidized bed opposed classifier jet mill is perfect for the super fine grinding of different dry materials with a precise control over the particle´s top cut thanks to its integrated classifier wheel design, using the Hosokawa Alpine Turboplex classifier head ATP. This micronizer can be used to pulverize different coarse products to finer powders and within different industries where micronization might be needed, such as minerals, chemicals, food, pharma, cosmetic, etc.
This grinder is able to process hard coarse products up to approx. 10 Mohs´ hardness without much wear and reaching an extremely high end-product fineness values between d97 4 to 100 microns top size (product dependent) at the lowest possible energy consumption. The comminution takes place in the bottom part of the grinding chamber where the nozzles inject compressed gas at high pressure onto the fluidized bed full of feed material and the resulting jet projects the particles against each other breaking them thus reducing their side. The comminution takes place in the center of the chamber far from the mill housing, hence resulting in extreme low wear within the grinding chamber turning this mill optimal for abrasive materials or those that require very low contamination in the final product. Within the same chamber, the air circulation brings the fines to the rotating classifier wheel where oversize grains are rejected to then return to the grinding zone for reprocessing, whereas the fine particles make it through the classification step to the next stage, normally the filter. Sometimes a cyclone is installed between the mill and filter or even a secondary air classifier or cyclone-classifier. Thanks to the great required process air volume, very limited temperature increase during grinding is to be expected compared to other granulation and crushing technologies. Adjusting the final particle size distribution can be easily done by changing different parameters, such as the compressed gas pressure, grinding nozzle diameter or its design and the classifier wheel speed, air volume, filling level and feeding rate, etc.
