Study of the wear process of technological surfaces of saw gin grates

This paper presents the results of theoretical studies process wear technological surfaces saw gin grates. Mathematical expressions are obtained, with help which it is possible to determine statistical characteristics raw roller and indicated that grate, in operation from impact roller, occurs as a result abrasive deposited on it. A rod model interaction between grate has also been studied, basis depth penetration contact surface working zone grate. The possibility reducing grates by increasing area their reducing, due this, probability grains getting into same place, substantiated. new convex shape proposed. Calculations have determined this case service life increases up 50%.
