DetailsA pin mill is one of the most commonly used impact mills for grinding bulk solid materials to medium fineness. The mill can accept feed materials with a particle size ranging from 20 microns to 0.5 in. and a Mohs hardness of 4, reducing particles down to as small as 10 microns, depending on the mill type and feed size.
DetailsWe can supply hammer mills for size reduction tasks that mainly need to be done by means of impact and blows. We build them in sizes from 450 x 600 to 1000 x 2500 mm circle of rotation diameter x working width and with drives up to 200 kW. It is possible to make hammer mills that are relatively insensitive to foreign bodies.
