Abstract: The equipment for the production of slabs in mineral grits bound with resins, comprises: a support frame, at least one lower plate, locked together with the frame, comprising at least one positioning zone for at least one mold having at least one forming cavity, open at the top, to contain a mix comprising the materials necessary to obtain the slabs, at least one pressing assembly comprising an upper plate movable, with respect to the frame, from an upper position of loading/unloading the mold in/from the positioning zone, to a lower position of pressing the mix inside said forming cavity, vibrating means associated at least with the lower plate, and an airtight chamber, communicating with suction means, adapted to reduce the pressure to a value lower than the atmospheric pressure, containing the mold, where the chamber is interposed between the lower plate and an upper closing element opposite the lower plate.
