Obtaining the sintered compounds out of metallic powders represents a major technological problem, powder milling being here of first importance. The present paper tries to bring a contribution to the elastic system study of vibrating mill with spatial motions for milling the metallic powders. For milling the metallic powders, I proposed the vibrating mill with spatial movement. The mill is formed by: the tank of the mill — the proper working space; the driving system; the elastic supporting system. The elastic supporting system is formed by an even number of springs, of identical elastic characteristics, to keep the symmetry of the group of “n” elastically forces with respect to the rotation axis of the driving system. The elastic system realizes the connection of the mill with a rigid and fixed support. In the general motion of the rigid, assimilated to the vibrating mill, it acts upon the elastic system, and none of the deformations in the springs does nor exceed the imposed condition, so that the tangential unitary effort appearing in the section of the cells should not exceed the admissible value. In this paper, it establishes the conditions for protect the elastic system of vibrating mill with spatial motions, and proposes the driving system in manner to manage the milling process.
