  • Publication number: 20130126647
    Abstract: A comminution reactor includes an inlet chamber, one or more processing chambers, and a discharge chamber. Each chamber includes a rotor, and the chambers are separated by split divider plates. The reactor is designed with assemblies comprising portions of the reactor walls and divider plates which rotate open to allow access to the inside of the reactor, including the shaft and attached rotors. The design of the rotors and vortex generators on the reactor walls direct the flow, optimize comminution, and minimize wear on the apparatus.

  • Patent number: 7985019
    Abstract: A method and an apparatus for continuously mixing two flows, a first, larger flow and a second, smaller flow. The second flow is introduced counter-directed into the first flow. The apparatus comprises a T pipe where a first connection constitutes an inlet for the first flow. A second connection, at 180° in relation to the first connection, constitutes an inlet for the second flow. The second flow is led into the first flow through a conduit within the T pipe. The first connection is provided with a conical portion in which are provided a number of holes, so that the first flow is throttled and divided up into a plurality of subflows immediately before the mixing operation. A third connection is oriented at 90° in relation to the other connections and constitutes an outlet for the intermixed flows, which implies that the intermixed flows are caused to change direction immediately after the mixing.

  • Publication number: 20070153625
    Abstract: The disclosure relates to a method and an apparatus (1) for continuously mixing two flows, a first, larger flow (2) and a second, smaller flow (3). The second flow (3) is introduced counter-directed into the first flow (2). The apparatus (1) comprises a T pipe (4) where a first connection (6) constitutes an inlet (20) for the first flow. A second connection (7), at 180° in relation to the first connection (6), constitutes an inlet (21) for the second flow (3). The second flow (3) is led into the first flow (2) through a conduit (13) within the T pipe (4). The first connection (6) is provided with a conical portion (10) in which are provided a number of holes (12), so that the first flow (2) is throttled and divided up into a plurality of subflows immediately before the mixing operation.
