A process for separating carpet fibers from carpet backing uses a grinder of the type having a rotor with a plurality of vertically spaced cutter discs and a fan disc below the cutter discs. Sections of carpet are fed into the grinder which grinds the carpet, separating the fibers from the backing and breaking the backing into relatively small particles. The grinder is connected with a series of ginning equipment for removing the ground backing from the fibers.

An arrangement for dust blocking in a cone crusher, a cone crusher, and a method for the dust blocking and manufacturing the cone crusher, in which a crusher head is supported by a support cone. A linear actuator vertically moves the crusher head for setting adjustment and/or tramp iron release. A lower surface of the support cone, at least in part, defines a downwards opening annular cavity. The crusher head radially movably supports a seal ring. A lip is formed for the annular cavity by the seal ring. A slip ring extends into the annular cavity beyond the seal ring and forms a counter-surface for the seal ring. The slip ring at least in part defines a pressurised gas supply channel and an entry channelling interconnecting the pressurised gas supply channel to the annular cavity.

The invention is directed to a glass disposal system. A device (10) for breaking glass articles is provided, which comprises an inlet (12) and an outlet (26) in fhrkl communication with one another and having a rotating member (16) interposed therebetween. The rotating member (16) is attached to, and capable of being rotated by, a motor (24). The inlet (12) to the device (10) opens onto the rotatable member (16) and the outlet (26) is substantially tangential to the rotatable member (16). The rotatable member (16) comprises portions to create an overall flow of air from the inlet (12) towards the outlet (26), and subsequently expels the particles of the broken object away from the rotatable member (16) through the outlet (26). The invention extends to a conduit (60) for the system.
