Air-pressure mills are used for very fine milling (to a grain size of 0.001–0.05 mm). Ground material is introduced into ejectors facing one another. Compressed air under a pressure of 0.4—0.8 meganewton per sq m (40–80 kilograms-force per sq cm), super-heated steam, or hot gaseous combustion products are introduced into the ejectors.Outlet pressure of millOutlet pressure of mill Products.
