Abstract

The results of a study of the structural–mechanical properties of granules of various types of mineral fertilizers prepared on the basis of ammonium phosphates by measuring the force necessary for the destruction of the granule upon uniaxial compression between two parallel planes and deformation along the compression axis are given. Using X-ray microtomography and raster electron microscopy, the structure of granules is studied. The results of the calculation of the coefficient of local stress concentration, as well as activation energy of destruction and strength of the granules, are given.

Keywords:
