Abstract. The physical modeling of fine loose material deformation between two rigid surfaces of disintegrators is conducted. The granite particles of size -2+1 mm have been taken as working material. The experimental dependences of deformed zone thickness are obtained during compressing of material layer between parallel surfaces for different combinations of the zone's length and width. The character of dependences between zone’s thickness to radius ratio and zone’s length to radius ratio is sufficiently non-linear.The linear dependence for dimensionless complexes of deformed zone's thickness to radius ratio and the radius to the perimeter of minimal cross-section ratio is set. The results of work allow to determine the deformed zone parameters of disintegrators with working surfaces extended along one of directions, for example, jaw crushers or rod mills.
Keywords: disintegrator, crusher, mill, working surface, deformed zone, loose material.
