Abstract


The article presents the results of the developed processes of pelletizing complex fertilizers taking into account the physical, chemical and rheological properties of their original components. The pelletized powders and blends differ in content by elastic, brittle and hygroscopic components, as well as the presence of various special agents. The most effective are the products which have granular form. The article gives recommendations on the choice of design parameters and equipment in particular pelletizing process by pressing and molding taking into account the nature of the material and its structural and deformation properties, in general. It is established that the change in the angle of the blades granulator from 50 to 100 allows of regulating the quality of additional grinding and mixing of the components of the charge with a maximum output of marketable fraction.

Key words
