Abstract: Dust-free and non-caking granular materials, especially broken granules from fertilisers and salts are prepared by applying coatings consisting of polymer mixtures. The granular materials have applied to them aqueous suspensions or solutions of a) urea-aldehyde condensation products and/or alkylol ureas and b) polyenes, the amount of solid applied being from 0.3 to 4.0% by weight, based on the amount of granular material.

Abstract: In a method of manufacturing ammonium nitrate granules which may contain calcium carbonate and have N contents of at least 25 wt.%, gypsum is added to the mash containing the ammonium nitrate at a temperature of 120 to 160 DEG C and the mixture is set aside for 5 to 20 minutes at this temperature before it is shaped.
