ABSTRACT:
In the dynamic concentration of a suspension, in which the suspension is fed into a filter which has a driven stirring device, and in which the suspension forms a filter cake which is continually remixed by stirring with the suspension being dehydrated and maintained in a liquid state up to a desired degree of concentration, the power consumption of the stirring device is measured, in particular the torque is measured, and the intensity of the stirring motion is controlled in accordance with the measured torque by causing a change in the number of revolutions per minute of the stirring device in response to the torque transgressing an upper limit or a lower limit.
