Development of the Technology of Capsulated Fertilizers Based on the Composition Natural Sorbent-lignin and Determination of Their Resistance to Attrition

The principal technological scheme of capsulated fertilizers production with use of lignin and natural dispersed sorbents as a film-forming composition has been developed. The process of fertilizers capsulation in conditions of a boiling layer is described. Material balance of capsulation process has been calculated. Resistance to attrition of sample units have been investigated in the laboratory conditions.
