FIELD: production processes.
SUBSTANCE: invention refers to method of substance granulation in fluidised layer and granulator for its implementation. Method consists in the following: by means of fluidising air fluidised layer of granules of granulated substance which is supplied to fluidised layer in the form of inoculating seeds is formed and substance or liquid for granules growing are continuously supplied to fluidised layer. Fluidising air flow is divided into many flows which are supplied to various zones of fluidised layer with different rate within limits from minimum in first zone, enough for maintaining fluidised layer, to maximum in second zone, required for formation of circular motion, actually, eddy motion of granules of granulated substance in fluidised layer and its maintaining around horizontal axis.
EFFECT: method of granulation in fluidised layer and granulator for its implementation (versions) is described.
