Description:
Partikeln - als Versuchsgut dient weißer Pfeffer - werden in verschiedenen Bereichen der Turbomühle beansprucht: beim Einlauf in die Mühle, bei der Vorzerkleinerung an den Schlagleisten des Rotors bzw. durch eine Schlagscheibe und im rotierenden Gutring zwischen Rotor und Mahlrost (mit und ohne Mahlbacken). Schließlich erfolgt der Austritt durch den Mahlrost (Zeitdehnung 8000 B/s)
In order to detect possibilities of improving the design of mills and the energy utilization, the stresses to which the particles were exposed in the individual areas of a turbo-mill were recorded and analsed with the aid of high-speed cinematography. The tests with white pepper were executed at a rotor circumferential speed of u=40 m/sec., with a material throughout of M[M]=150 kg/h and with varying configurations of the peripheral grid. The tests covered the percentage of material comminuted by the first impact, the penetration into and the discharge from the baffle plates of the rotor, the conditions prevailing in the rotating material circle between rotor and peripheral grid, as well as the the passing of the particles through the peripheral grid
