THE ELASTIC SYSTEM STUDY OF THE VIBRATING MILL WITH SPATIAL MOTIONS FOR MILLING THE METALLIC POWDERS

Obtaining the sintered compounds out of metallic powders represents a major technological problem, powder milling being here of first import ance. The present paper tries to bring a contribution to the elastic s ystem study of vibrating mill with spatial motions for milling the met allic powders. For milling the metallic powders, I proposed the vibrat ing mill with spatial movement. The mill is formed by: the tank of the mill - the proper working space; the driving system; the elastic supp orting system. The elastic supporting system is formed by an even numb er of springs, of identical elastic characteristics, to keep the symme try of the group of ''n'' elastically forces with respect to the rotat ion axis of the driving system. The elastic system realizes the connec tion of the mill with a rigid and fixed support. In the general motion of(he rigid, assimilated to the vibrating mill, it acts upon the elas tic system, and none of the deformations in the springs does nor excee d the imposed condition, so that the tangential unitary effort appeari ng in the section of the cells should not exceed the admissible value. In this paper,it establishes the conditions for protect the elastic s ystem of vibrating mill with spatial motions, and proposes the driving system in manner to manage the milling process.
