Process for continuous agglomeration in fluidized bed
In the fluidised-bed agglomeration process, the pulverulent solids (4) together with a granulation liquid (3) are sprayed into a fluidised bed (13) operated by fluidising air (2). The finished granules are discharged from the fluidised bed (13) through an air classifier (15). The granulation liquid...

Summary: | In the fluidised-bed agglomeration process, the pulverulent solids (4) together with a granulation liquid (3) are sprayed into a fluidised bed (13) operated by fluidising air (2). The finished granules are discharged from the fluidised bed (13) through an air classifier (15). The granulation liquid (3) together with motive air is conducted through an axially directed three-component nozzle (12) arranged in the centre of the fluidised-bed granulator and, at the same time, the solids (4) are fed by means of a separately and concentrically supplied motive air stream through the annular gap of the three-component nozzle (12) into the fluidised bed (13). In this manner, a three-phase mixture of solids (4), granulation liquid (3) and motive air is produced in the centre of the fluidised bed (13). |
