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.
