Method for producing calcium nitrate granules at controlled humidity and temperature conditions using fluidised bed granulators

A process for producing calcium nitrate granules where a calcium nitrate melt is sprayed into a re-circulating bed of a first fluidised bed granulator (10), wherein the re-circulating bed is supplied with air that has been conditioned to a relative humidity of less than 30% at 40°C and heated to a t...
