Abstract
(EN)
What is described is a top-loading wheeled shredding mill with a horizontally moving ram (4) and with shredding units (7, 107 and 8, 108) opposite this ram. The loading chamber (2) of the mill is provided with an upper preliminary chamber (19) which is sealed from the outside by the waste loading means before the top hatch (3) of the loading chamber of the said mill is opened in this preliminary chamber. On completion of loading, and only after the said top hatch has reclosed, the said feed means can return to the low position to collect further waste, and the said preliminary chamber opens. The shredded waste is fed by gravity to an underlying conveying and remixing system, preferably of the screw type (20, 21), which feeds the said waste to the lower initial part of a second, upwardly inclined, screw conveyor (30) in such a way that any liquid present in the waste remains in the lower part of this conveyor and can be distributed uniformly over all the waste in transit. The waste is subsequently moistened to the correct degree inside the sterilization containers (34), by suitable means (39) located in the piston of the station (33) for loading these containers.
(FR)
L'invention concerne un broyeur à roulettes à chargement par le haut comprenant un coulisseau (4) qui se déplace horizontalement et des unités de broyage (7, 107 et 8, 108) opposées à ce coulisseau. La chambre de chargement (2) du broyeur comprend une chambre préliminaire (19) supérieure qui est fermée hermétiquement de l'extérieur au moyen d'un organe de chargement déchets avant que l'orifice de chargement (3) supérieur de la chambre de chargement ne soit ouvert dans la chambre préliminaire. Lors d'un chargement, et uniquement une fois que l'orifice de chargement est refermé, l'organe d'alimentation peut revenir à une positon inférieure afin de collecter d'autres déchets, la chambre préliminaire s'ouvrant alors. Les déchets broyés sont fournis par gravité à un système de transport et de nouveau mélange sous-jacent, de préférence, du type vis (20, 21), qui fournit lesdits déchets à la partie inférieure initiale d'un second transporteur à vis (30) incliné vers le haut, de sorte qu'un liquide quelconque présent dans les déchets reste dans la partie inférieure du transporteur et peut être réparti uniformément sur la totalité des déchets en transit. Lesdits déchets sont ensuite humidifiés afin de corriger le degré à l'intérieur des récipients de stérilisation (34) à l'aide de moyens appropriés (39) placés dans le piston de la station de chargement (33) desdits récipients.
