Alpine Spiral Jet Mills are frequently used in the pharmaceuticals industry and also for the manufacture of fine-grade chemicals for ultrafine size reduction of dry materials with a crystalline structure up to a Mohs hardness of 3.
Typical operating advantages are:
Spiral Jet Mill – AS Aeroplex
Because the AS Aeroplex Spiral Jet Mills have no rotating components, there are consequently no bearings and shaft seals and thus no lubricants are used so contamination from these sources is impossible, which leads to high product quality. The simple geometry of the mill components makes them easy to clean and also permits sterilisation of the entire mill.
Alpine jet mills are used predominantly for high-grade pharmaceutical product for example antibiotics or fine-grade chemicals, especially when high demands are made of the purity and fineness of the end products. The most common requirements using a maximum feed size of approx. 1.5 mm are end-product fineness values with a d97 ranging between approx. 5 and 30µm.
