Abstract

An apparatus for mixing solid particles and a liquid, especially wood chips and glue. A motor-driven stirrer in a cylinderical trough continuously mixes the materials which enter at one end of the trough and are discharged at the other end. The outlet of the trough has a pivotable throttle with a counterweight which controls the degree of opening of the throttle. An electrical signal related to the load on the stirrer motor is the control signal for a control loop whose final control element displaces the counterweight to maintain the electrical load of the drive motor approximately constant.
