Title:
PRODUCTION OF PARTICULATE MATTER HAVING PARTICLE SIZE DISTRIBUTION PERIODICALLY OSCILLATED AND DEVICE THEREFOR
Document Type and Number:
Japanese Patent JPH10128099
Kind Code:
A
Abstract:
To obtain two or more fraction having different particle distributions somewhat continuously.
Particulate matter is produced by a continuous fluidized bed spray granulation. In this case, the particulate matter is discharged by a discharge device having classifying effect by an area ratio of time integral of a discharge surface 'f' to floor area F of a fluidized bed causing periodic vibration. By decreasing the area ratio f/F, the vibration is controlled, and by further decreasing it, a change of a amplitude is increased. Fractions of different particle size distributions are obtained by fractionally removing particulate matter during one period. The area ratio f/F is 5 0/00-0.1 0/00.
