On the Shearing Characteristics of Fertilizers in the Revolving Type Shear Tests

Abstract

The shearing characteristics of eight kinds of fertilizers were tested in the revolving type shear machine, the main shearing part of which is the vane or radial teeth type vertical rotor in the center of the cylindrical sampler.
Fertilizers tested showed as same characteristics as when they were tested in the common type of direct shear machine which has a shear box consisting of two parts, the upper frame and lower frame. Consequently, the shearing characteristics of fertilizers obtained from the common mono-plane shearing tests can be applied to three dimensional shearing phenomena, which arise in hoppers of fertilizer distributors.
