Abstract

The article presents the results of theoretical studies of the process of crushing feed in a vertical stream. A mathematical model of the trajectory of the feed particle in the working chamber of a planar rotary shredder has been developed. The factors influencing the probability of destruction of a particle when it encounters a knife and an anti-cutting element are determined, and their connection with the design parameters of the shredding apparatus is established.

The results of experimental studies of the process of green mass grinding are presented. The effect of the number of knives of a planar rotary shredder on the granulometric composition of the feed was studied experimentally. An improved design of the shredding apparatus which involves fixing two symmetrical knives on one holder is proposed. It
will increase the probability of meeting feed particles with cutting elements by 50 %. The proposed design of the rotor of a planar shredding device allows to increase the degree of feed crushing without changing the parameters of the working chamber or anti-cutting elements.
