Multifunction wood flour machine is supported by bearing housing end of the spindle by the motor via belt drive, drive shaft and secured to the spindle rotation speed of the rotating knife. Make sharp teeth grinding block rotating blade with the ring on the composition and reasonable, compact pair, so that the material tightly friction in the rotating air flow and strong impact grinding, and leaves gaps between blocks and grinding, grinding again By adjusting the energy of the pulverized material between 40 mesh -325 mesh. The device is compact, small size, low power consumption, high efficiency, smooth rotation, low noise, reliable seal, no dust pollution, self-cooling function is good, simple to install, easy to dismantle and easy to repair, replace damaged pieces convenience. Mainly applied to sawdust, poplar powder, ceramics, body black, pigment, tobacco, chemicals, pharmaceuticals, dyes, paints, pesticides, metallurgy, food, feed, plastics, plant fibers, cellulose, wood flour , recycled rubber and other industries for crushing low to medium hardness of material. Multifunction wood flour machine is a husk, corn, rice, chemicals, pharmaceutical intermediates, dyes, paints, pesticides, metallurgy, ceramics, food, feed, non-metallic mining enterprises and scientific research institutions, as fine until superfine powder Processing the best, most effective and most economical equipment.
