For fine or coarse grinding the oval ring mill and the pin mill are comparable. The MS20 can be useful if tight size distributions are required. Finally, the fluidised bed air jet mill does not seem to be well suited to grinding organic powders. This type of mill does not have any particular qualities with respect to particle size and ...
Food mills typically come with interchangeable discs with holes of varying sizes for puréeing different foods. If you want to make seed-free jams and berry sauces, look for a mill with an ultra-fine disc (1 to 1.5 millimeters). A fine disc (2 millimeters) will remove both skin and seeds from cooked tomatoes and create creamy soups and silky ...
Fine grinding mills can be categorized into five groups [48]: impact mills, ball media mills, air jet mills, roller mills, and those of some other type, including disc mills. Impact mills and air jet mills are based on single impacts, as presented in Fig. 4 a, while ball media mills utilize double impacts between metal surfaces ( Fig. 4 b).
