    摘要： A wet comminuting machine is provided with a sieve which is located at the mill base outlet and has orifices of such dimensions that they block the passage of grinding medium. Opposite the exit surface of the sieve a plate, which can be moved toward the sieve, is provided, on the side facing the sieve, with elements for pushing through the orifices of the sieve, and can be moved manually, pneumatically, hydraulically or electrically by means of a connecting rod. The elements of the movable plate are arranged in alignment with the orifices of the sieve, and are in the form of strips or spikes, depending on the particular design of sieve.

    摘要： Magnetic recording media are produced by preparing a dispersion of anisotropic magnetic materials in solution in an organic binder using dispersants and further conventional additives, applying the dispersion in the form of a layer onto a nonmagnetic substrate and solidifying the applied magnetic layer, by a process in which a cylindrical grinding chamber is used which is provided with an anchor stirrer or helical stirrer and contains grinding media whose specific gravity is lower than that of the magnetic material.
