Granulation of powdered materials in a high-speed granulator

Granulation of powdered materials in a drum-type high-speed granulator was studied. A mathematical model was constructed for describing the granulation in a high-speed granulator in which two processes, coagulation and disintegration, are combined. The constants of the integral transform core for coagulation and disintegration were determined from the experimental data obtained. The suggested mathematical model was shown to be adequate to the real process of granulation of a hydrophobic additive to asphalt concrete mix.
