Abstract
Granules of magnesium salts are obtained by spraying onto agitated feed particles of the salt a small amount of a dilute aqueous solution of a synthetic poly hydroxy-substituted compound, such as polyvinylalcohol, and drying the resultant agglomerate. It is especially suitable to carry out the granulation process in a warm air fluidized bed using feed particles of mainly below 200 microns producing eventually a low bulk density product mainly in the range 200-100 microns. The granular salts have a particle size of from 0.15 to 1.0 mm and a free-flowing bulk density of from 0.3 to 0.6 kg/l.
