STUDY OF ROLL CRUSHER DYNAMICS DURING MATERIAL CRUSHING
Based on Newton’s second law, a mathematical model of roll dynamics during material rupture between tyres was developed. As a result of analytical studies, the dependence of value of the roll movement along the bed shear on the crushing force and the spring pre-tightening force is obtained. Comparative analysis of the dynamics of the ДЧГ 900×700 crusher was carried out during fractional preparation of various types of raw materials. Recommendations on preliminary tightening force of tension device springs are proposed to ensure rational operating conditions of crushing machine during grinding of different types of solid fuel.
