Hosokawa Alpine air classifiers come into their own, which allow infinitely adjustable separation cuts for upper particle size limitation or for removal of the dust content. Our classifiers can be operated inline with the grinding plant but equally efficiently offline. PARTICLE SIZE DISTRIBUTION OF A PA-6 POWDER REQUIREMENTS › psd 10 –100 µm

Cryogenic Grinding. The feed material is cooled down to the "glass transition temperature" by liquid nitrogen. With the specially designed Hosokawa Alpine Contraplex pin mill – in combination with our Stratoplex classifier – we guarantee innovative technology from one single source for highest quality in grinding of rubber.

Due to this, the Hosokawa Alpine cryogenic grinding process with CO2 or LN2 is a proven technology that makes the nut easier to mill. A screw cooler cools the feed product in a nitrogen bath down to minus 30 to minus 80 degrees. A cryogenic control valve unit for precise dosing of the cooling agent, as well as a temperature control and a O2 ...
