Centrifugal fluidising granulator and method for powder coating granulation

摘要

The centrifugal fluidizing granulator for powder coating granulation has a sensor (40) for detecting changes of viscosity of the growing particles by means of a load cell or a displacement detector; and output signal of the sensor (40) is compared with the data stored in a memory contained in a control unit (50) which determines whether the growing particles are in their wetted state or dried state. The control unit (50) controls the spraying of the liquid and the dispersion of the guest powder based on the result of the comparison.
