摘要

The mill has a grinding device (1) for grinding dry ice and provided with opposite rollers (20, 30). A milling strip is arranged between the two opposite rollers and forms a milling gap on two opposite sides of the strip by one of the rollers. The rollers are rotated at the milling strip in the area of a dry ice supply. The milling strip is arranged centrically above an outlet (90) of the grinded dry ice. Surfaces of the milling strip are convex designed and used for grinding. The strip is guided in guiding grooves of a housing (40) to adjust a distance of the strip to the rollers.
