Language: English

Abstract. Process of gravitational treatment of granular materials in the pulp horizontal flow is accompanied by bearing stream flowing within differently inclined surfaces and by downstream of condensed pulp. In the article, method for calculating design parameters of horizontal classifier is validated, which is based on construction of trajectories of solid particle motion.

For this purpose, process of liquid elementary particle moving in the flow is considered. Trajectory of the liquid elementary particle or solid particle motion is constructed by determining the particle current coordinate in accordance with the Lagrange method. Trajectory of solid particle motion in characteristic sections of horizontal classifier is constructed with the help of expressions for calculating values of sedimentation depth increment.

Keywords: gravitational separation, horizontal classifier, motion trajectory.
