Abstract

Described is a pressure-resistant mixer with a feed opening (15), a rotating mixing container (1) with a drainage device (20) and with mixing tools (17) arranged eccentrically to the axis of the mixing container axis (35) inside the mixing container (1), and with drive motors (6, 22) and drive devices (33, 34) for driving the mixing devices (17) and/or the mixing container (1). In order, on the one hand, to avoid sliding seals in contact with the materials being mixed, and, on the other, to avoid having to use extremely large size seals, is proposed in accordance with the invention to position the mixing container (1) inside a stationary pressure vessel (3).
