Abstract

La presente invenzione riguarda un procedimento per la pressatura a secco di un materiale granulare o polverulento, un dispositivo atto ad essere utilizzato per attuare la pressatura e un apparato di pressatura che comprende il dispositivo.Il procedimento secondo l'invenzione comprende una fase in cui contemporaneamente viene sia variata la profondità dello stampo e sia rasata la superficie superiore del materiale contenuto nello stampo.Il dispositivo comprende un basamento, un corpo di supporto dello stampo inferiore e una pluralità di pistoni e cilindri idraulici alimentati da un organo divisore di flusso.L'invenzione consente di ottenere qualsiasi profilo di distribuzione del materiale nello stampo, nella direzione dei mezzi di rasatura, in modo da compensare le inadeguatezze di distribuzione.The present invention relates to a process for the dry pressing of a granular or powdery material, a device suitable for being used for carrying out the pressing and a pressing apparatus which comprises the device. The method according to the invention comprises a step in which simultaneously the depth of the mold is varied and the upper surface of the material contained in the mold is trimmed. The device comprises a base, a support body for the lower mold and a plurality of pistons and hydraulic cylinders fed by a flow dividing member. invention allows to obtain any distribution profile of the material in the mold, in the direction of the shaving means, so as to compensate for the inadequacy of distribution.
