ABSTRACT:
In a rotation granulator, the injection nozzles for the powder are provided along the jacket surface of the granulator container over the rotary table, so that the powder will arrive directly in the range of the stronger flow. In order to prevent any interruptions of the operation due to the filter part, a two-chamber system is proposed in which the first and second chambers may be alternately cut off. This makes it possible to operate the installation without any interruption. In order to control the air supply, the rotary table is mounted so that it may be moved up and down, in order that the width of the air gap between the rotary table and the inner wall of the conical casing may be adjusted. Lastly, a device for taking of samples provides a system of sluices or channels by which the low-pressure space of the granulator is actively prevented from being in direct contact with the free atmosphere.
