摘要: There is disclosed a process of granulation comprising dropping as liquid droplets the melt of a substance solidifiable by cooling or drying through a zone having a sufficient vertical distance to allow solidification of the droplets, forming a fluidized bed of the solidified droplets on the bottom of the said zone, spraying the same or a different melt from the above mentioned substance as fine liquid grains along with a gas stream into the fluidized bed thereby forming a spouted bed of the solidified droplets in the fluidized bed, coating and enlarging the solidified droplets with the fine liquid grains inside the spouted bed, and discharging the obtained large sized granules from the fluidized bed. There is also disclosed an apparatus for practicing the process.

摘要: In a granulator of the jet layer type, all the liquid jetting openings are located in a passage for a gas jetted from the gas jetting opening and each liquid jetting opening is located at a position higher than the gas jetting opening by a vertical distance smaller than the inner diameter of the gas jetting opening. The granulator may have an additional device such as an excess size-having particle-collecting means, a five particle treating means, a rectifying pipe member, a fuffer member and a hindrance and breakage member.
