OPERATING METHOD OF FLUIDIZED-BED GRANULATOR, AND FLUIDIZED-BED GRANULATOR

摘要

Provided are an operating method of a fluidized-bed granulator; and a fluidized-bed granulator which can stably and consistently control the detention time of granules in a fluidized bed. The operating method of the fluidized-bed granulator maintains a seed ingredient and an additive ingredient in a floated state by using compressed air in a fluidization chamber to produce a target granule. The operating method of the fluidized-bed granulator comprises the steps of: maintaining the seed ingredient and the additive ingredient in a floated state in the fluidization chamber by using a main compressed air spraying part which supplies main compressed air from the lower part of the fluidization chamber; and discharging auxiliary compressed air upwards from the end part of a partition arranged on the lower part of the fluidization chamber.;COPYRIGHT KIPO 2016
