FIELD: process engineering.
SUBSTANCE: invention relates to granulation in fluidised bed. In compliance with proposed method, appropriate fluidised bed composed by material particles in is maintained in pelletiser. Flow containing fluid for pellets growing and flow of nuclei to accelerate pelletising are fed into pelletiser. Note here that prior to feed of said flow, its portion is diverted for use in pelletiser to make nuclei for fluidised bed.
EFFECT: controlled grain size, decreased wastes, simplified process.
