Press for vacuum vibro-compression of slabs or blocks or articles of agglomerated or ceramic material

Press for vacuum vibro-compression of slabs or blocks or articles of agglomerated or ceramic material, comprising a ram with a pressing surface provided with means for generating a vibratory movement, the means comprising first and second sets of vibrating devices, each of the vibrating devices being provided with at least one rotating shaft with an eccentric mass, the at least rotating shaft of each vibrating device of one of the first and second sets rotating in an opposite direction to the at least one rotating shaft of each vibrating device of other of the first and second sets, wherein each set of vibrating devices comprises at least two vibrating devices having respective rotating shafts that are non-coaxial and are interconnected by kinematic connection means for rotating the at least two vibrating devices in synchronism, said vibrating devices of each of the first and second sets having parallel and adjacent shafts, wherein each vibrating device of the first and second sets comprises a plurality of the eccentric masses spaced along the rotating shafts of the sets, wherein each rotating shaft of the vibrating devices is divided into coaxially interconnected segments, wherein each segment forms a shaft of a rotating motor associated with at least one eccentric mass of the plurality, so as to form along each of the rotating shafts of the sets a row of coaxial vibrating stages, and wherein the kinematic connection means kinematically connect the non-coaxial shafts between the vibrating stages.
