Pin Mill is specially designed to deal efficiently and economically with a wide range of materials and can be easily adjusted to give the fineness required from a coarse granulation to finely ground powder.
Pin Mill Grinding is gradually done from the centre to the periphery of the Rotor, allowing heavy pieces of material to be reduced by stages to the fineness required. Constructional materials and operating components are manufactured out of the best applicable raw materials, so as to yield close particle size for a similar product.
The PIN MILL is a fine impact mill with two driven pin discs. In counter rotating mode, much higher relative speeds are possible than with the UPZ fine impact mill which has only one driven pin disc. The highest relative speed developers at the outermost pin rows can be up to 250 m/s. The feed material should be brittle with a maximum hardness of 3-Mohs. The fineness can be adjusted by altering the pin disc speeds. The centrifugal force acts on both disc speeds. The Centrifugal force acting on both discs ensures that even moist, greasy and sticky products can be processed. The design with the wide- chamber housing is ideal for processing.
The feed material is often Embrittled by intensive mixing with liquid nitrogen.
The mill door can be opened wide to permit easy cleaning. Dependent on the machine size, product feed.
Is either from the front through the machine door or from the rear of the mill housing.
