Abstract
In a disk – shaped two-section granulator with coaxial sides, the preparation of granules from clay powder by the action of drops from binder fluid of the same diameter was studied. Optimal granulation time in the first and second sections, the corner of inclination and the rotation speed of the granulator are established, which contribute to the production of rounded granules with a sphericity of at least 0.85 (85%) and the same particle size distribution. It was established that value of the granules formed is determined by the size of the supplied droplets of the binder fluid, and the strength increases with increasing diameter. However, with increasing granule size, the tensile strength decreases.It is shown that the initial stages of the granulation process have the greatest influence on the potential mechanical strength of granules. A mathematical model of the diameter dependence of the granule on the diameter of droplet is proposed to the binder solution. It was shown best coincidence of results by the proposed mathematical model and the experimentally obtained data.
