Abstract

A granulated core material comprising potassium chloride and/or an ammonium phosphate is coated with a molten mixture of magnesium nitrate (as drying agent) and ammonium nitrate, the coating material being sprayed on to the core material while it is agitated in a co-current of warm air. The ammonium phosphate may be mono- or di-ammonium phosphate or ammonium polyphosphate. The core material may contain up to 0.3% of moisture and also recycled undersize and crushed oversize product containing up to 20% of the total ammonium nitrate sprayed. The coating material, which may contain up to 0.5% of moisture and 0.1-5% of magnesium nitrate (as MgO), may form at least 25% of the coated granules. The ratio of total moisture content to total magnesium nitrate (as MgO) content may be less than 1.8 to 1.
