Abstract
PURPOSE: To save various installations and quantity of heat required for supplying of seed particles by placing obstacle objects upward from the spouted bed of a spouted bed granulator, crushing part of spouting particles through collision, returning the same to the spouted bed right thereunder and using these as seed particles.
CONSTITUTION: In a spouted bed granulator 1, the particles of particle beds 18 are always flowed by the high velocity gas fed by pressure from a gas feed pipe 4, and spouting upward. Here, the liquid of a material which coats the particles and increases their sizes is sprayed by nozzles or the like through a supply pump 2 and a supply pipe 3, and are stuck and solidified to the flowing particles, whereby granulation is accomplished. At this time, part of the ejecting particles 17 are crushed by obstacle objects 5 provided in the upper space of the spouted bed, and are used as small particles serving as seed particles. By controlling the grain sizes and amount of the small particles formed by the crushing with an obstacle object variable mechanism 16, the grain size distributions of the granules from a granulator extraction port 6 are controlled within a desired range. The resultant granules are cooled with, for example, a cooler 7, whereby products 9 are obtained.
