Abstract
An apparatus for granulation and coating, wherein a rotary disk 2 provided at a bottom portion of a granulating vessel 1 is rotated for particles to centrifugally tumble on the rotary disk 2, while a powder material and a binder liquid are supplied into the granulating vessel 1. A position of a surface of a particle layer M in the granulating vessel 1 is detected by a sensor 18, to automatically adjust a position of a binder liquid supply port of a spray nozzle 13 in accordance with the detection signal informing of a change in the surface of the particle layer M.
Claims9
A granulation apparatus, comprising:
- a granulating vessel being of a circular shape in a horizontal cross-section;
- a rotary disk provided at a bottom portion of the granulating vessel and having an edge portion being concentric with a circle of the horizontal cross-section of the granulating vessel, said edge portion of the rotary disk spaced from an inner wall of the granulating vessel so as to form a peripheral slit;
- a powder supplying means for supplying a powder material into the granulating vessel;
- a binder liquid supplying means for supplying a binder liquid into the granulating vessel;
- a means for delivering gas into the granulating vessel through the slit;
- a means for rotating the rotary disk;
- a sensor for detecting a position of a surface of a particle layer supported on the rotary disk;
- and
- a first position adjusting means for automatically adjusting a position of a binder liquid supply port of the binder liquid supplying means in accordance with a signal from the sensor.
