Abstract

Broyeur déchiqueteur à taille hélicoïdale. Helical cut shredder.

Le broyeur comprend deux étages de broyage (8, 4) superposés dans lesquels sont agencés quatre arbres canne­ lés (19, 20, 27, 28), qui portent des couronnes dentelées (21) dans l'étage (8) et (29) dans l'étage (4). Les couronnes, à chaque étage, chevauchent celles de l'autre arbre du même étage et sont décalées angulairement sur leur arbre respectif de façon que leurs dents définissent un pas hélicoïdal dans le même sens que le sens de rotation des arbres. Les couron­ nes inférieures (29) sont deux fois plus minces et tournent deux fois plus vite que les couronnes supérieures (21). The crusher has two grinding stages (8, 4) superimposed in which are arranged four cane trees strips (19, 20, 27, 28), which carry serrated crowns (21) in the floor (8) and (29) in the floor (4). The crowns, at each stage, overlap those of the other tree of the same stage and are offset angularly on their respective shaft so that their teeth define a helical pitch in the same direction as the direction of rotation of the trees. Crowns nes inferior (29) are twice thinner and turn twice as fast as the upper crowns (21).

Application au broyage des immondices et déchets industriels. Application to the grinding of refuse and waste industrial.
