<p>The device for controlling and applying vibratory motions to machines and materials in order particularly to treat products to be vibrated, crushed, compacted, separated, is characterized in that it comprises the positioning from at least two coaxial axes (2 - 3) of two end-plates (4 - 5) rotatingly mounted with respect to a fixed structure (6), said end-plates providing for the positioning a plurality of lines of a plurality of satellites (L1, L2, L3, ...Ln) with unbalances (B1, B2, B3, ...Bn), some of them being driven by belt transmission means controlled by means for prepositioning (8 - 9) and winding the rotation control belt, said coaxial axes (2 - 3) controlling the angular positioning of the lines of the unbalanced satellites with respect to each other in order to exert unidirectional, multidirectional or mixed or oscillatory vibrations, said coaxial axes being associated with continuous or discontinuous out-of-phase means.</p> |
