Pin Mill Manufacturers

Pin mill is a type of intermediate crusher. The particles to be grinded are accelerated to a great speed and then crushed by means of an impact or fiction against the sides of the vessel. The air required for this acceleration is cooled to prevent the powder coating particles from sticking together. It consists of two horizontal steel plates with vertical projections arranged in concentric circles on opposing faces. The projections of the two face intermesh. The passage between the pins provides size reduction by impact and attrition. The material is suitable for grinding soft, non-abrasive powders, and low milling temperatures permit the processing of heat sensitive materials. The fineness of the grind may be varied by using disks with different pin dispositions.
