摘要： A vessel (1) contains a rotor disc (23) mounted for rotation around a vertical axis (17) and arranged to bound a processing space (31) disposed above it. The agglomeration and/or the coating of particles are accomplished by moving the particles by the rotation of the rotor disc (23) and by means of a gas, in particular air, passed upwardly through the processing space (31) and by spraying them with a liquid. The torque required for the rotation of the rotor disc (23) is continuously measured by means of a torque measuring member (75) disposed between the rotor disc (23) and the drive device (77) arranged to drive the same. The agglomeration and/or the coating operation is controlled on the basis of the time-dependent variation of the torque and/or of the first derivative of the same, and/or of a variable having relation to the torque and/or its derivative. In this way, agglomerated particles and/or particles provided with a coat may be produced, the particles possessing relatively accurately prescribed properties, such as for example particle sizes lying within a prescribed range.
