pin mill is very suitable for sticky and heat-sensitive material ,for it’s special structure. It is a product from German Hober technology.
Raw material for Pin Mill:
Foodstuff：sugar, rice, corn, starch, oat, flour, soya, pea, spice, cocoa, potato powder, salt, milk powder, onion, coffee, dextrose etc
Chemical: pigment, alumina, ferric oxide, copper, graphite etc
Plastic：polythene, PVC, rubber, bakelite, epoxy resin etc
Construction material：limestone, gypsum, fluorite, mica, kaolin clay, straw, shell etc.
Medicine：roots, bark, leaves , herb, bone powder etc.
The main parts of Pin Mill are housing, door, rotary disc, static disc, shaft, air sealing.( see attached drawing) There is a rubber ring between door and housing for prevent power out.
It’s milling zone is consist of rotary pins and static pins. Particles hit these pins and get split. Particles can get abundant times of hit because there are several rows of pins. The rotary pins can suck airs to reduce the heat generated by friction. There is a air sealing device to protect bearing keep clean.
