CONTRAPLEX CW II Pin mill with 2 driven pin discs for achieving high powder fineness values in the range of approx. 10 to 500 µm The wide chamber housing makes it possible to process even sticky materials Generously dimensioned mill door Easy to clean for product changes Optional: Versions for Pharma applications Optional: Versions for coating applications Principle of operation The Contraplex 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 with only one driven pin disc. The highest relative speed develops at the outermost pin rows and can be up to 240 m/s. The fineness can be adjusted by altering the pin disc speeds. The centrifugal forces acting on both discs ensure that even moist, greasy and sticky products can be processed. The design with the wide-chamber housing is ideal for processing these kinds of products. The feed material is often embrittled by intensive mixing with liquid nitrogen. The mill door can be hinged opened wide to permit easy cleaning. Features The CW wide-chamber housing prevents coating formation and thus blockages in the machine. In comparison with the pin disc Ø, the machine housing is oversized. This is why Contraplex mills are ideal for fine grinding greasy, oily, sticky and hygroscopic materials which tend to form deposits - either in continuous mode or at relatively long cleaning intervals. Besides the wide-chamber housing, the rotation of both pin discs (both speed and rotational direction are adjustable) is a distinguishing feature. The following important application advantages result:
