Development of a device for restoration of the flowability of caked fertilizers with justification of its design and operating parameters

Abstract

The article explores the possibility of use of a separate two-phase technology in agriculture to restore the flowability of caked mineral fertilizers. Flowability is one of the most important properties of fertilizers that determine their quality during storage and transportation. Flowability is understood as the property of a mineral fertilizer to flow freely under the influence of gravitational forces. Under certain environmental conditions, fertilizers may cake. To solve this problem in the preparation of fertilizers at agricultural enterprises, a new design of a preliminary grinder is proposed as a part of a two-phase technology. Based on the results of the experimental studies, the most rational design and operating parameters of the grinder have been determined. Practical recommendations on the possible use of the developed drum-type grinder for the destruction of other brittle materials in preparation for their introduction into the soil at agricultural enterprises are formulated.
