Research of the particle of bulk material movement by the sieve of the scissor-type separator

Abstract

Reducing the energy consumption of the separation process is a key task in developing equipment for the separation of bulk materials or mixtures of materials. The main direction of reducing energy costs for the separation process is to choose a method of separation taking into account the physical and mechanical properties of the bulk material or mixture of materials. The gravitational separators are the most promising designs of separators. The principle of operation of the gravitational separators is based on consideration of the physical and mechanical properties of bulk materials. In the gravitational separators, energy is not consumed by the drive of working bodies or surfaces. The design of the gravitational scissor-type separator is proposed in the article, as well as the results of theoretical studies of the bulk material particles movement by the separator sieve are released in the article. The proposed design of the gravitational scissor-type separator allows separating of bulk materials with different physical and mechanical properties due to the change of the angle of installation of the sieves. In addition, the proposed scissor-type separator is compact and easy to operate, and does not require energy costs for the separation process. As a result of the study the equations and conditions for substantiation of the rational parameters of the gravitational scissor-type separator which consider the physical and mechanical properties of the bulk material were obtained.
