Abstract (en)
[origin: US4382557A] A de-aerating agitating mill, especially for paints, pigments and the like in which the mixing chamber is closed off from a discharge chamber which may be subjected to reduced pressure. The closure is effected by a separator device consisting of a central disk which is attached to the stirrer or agitator shaft and rotates in a hole within a stationary part of the casing. A narrow, annular gap between the periphery of the disk and the rim of the hole acts as an outlet channel through which the ground or mixed stock is extruded. The shear stresses exerted on the stock rupture the material and burst any air bubbles which are then removed by the vacuum.
