Spiral jet mills are frequently used in the pharmaceuticals industry and also for the manufacture of fine-grade chemicals.

Because the Aeroplex spiral jet mills AS have no rotating components, there are consequently no bearings and shaft seals, and thus no lubricants are used. Contamination from these sources is therefore impossible.

The simple geometry of the mill components makes them easy to clean and also permits sterilisation of the entire mill.

• Spiral jet mill for the superfine comminution of soft materials (to about Mohs' hardness 3) which display brittle-crystalline fracture behaviour in the fineness range of 10 to 150 µm
• Design (figure): flat-cylindrical grinding chamber without rotating elements
• Top section in hinge-back design for easy opening, closing and removal

The most common requirements at a max. feed size of approx. 1.5 mm are end-product fineness values with a d₉₇ ranging between approx. 5 and 30 µm.
