  • Patent number: 11697120
    Abstract: An impact crusher for grinding and separating solid material has a base and a rotor on the base having an upright shaft defining an upright rotor axis about which the rotor is rotatable and a plurality of vertically spaced and radially horizontally outwardly extending plates each having an outer periphery. A drum fixed on the base spacedly surrounds the rotor. An array of axially extending and angularly substantially equispaced replaceable ribs is provided on an inner surface of the drum. A respective plurality of impact hammers are angularly substantially equispaced around the outer periphery of each of the disks. Respective mounting pivots support the hammers on the outer peripheries of the plates for pivoting about respective hammer axes parallel to the rotor axis so that rotation of the rotor grinds material between the hammers and the ribs. Formations between the mounting pivots and the respective disks enable radial adjustment and fixing of the hammer axes relative to the rotor axis.

  • Patent number: 11638922
    Abstract: An impact crusher for grinding and separating solid material has a base, a rotor on the base having an upright shaft defining an upright rotor axis about which the rotor is rotatable, and a drum fixed on the base, spacedly surrounding the rotor, and formed by a pair of generally semicylindrical drum shells fitted together at a plane including the rotor axis. An array of axially extending and angularly substantially equispaced replaceable ribs is provided on an inner surface of the drum. A plurality of impact hammers are angularly substantially equispaced around the rotor and orbitable past the ribs on rotation of the rotor.

  • Patent number: 9789516
    Abstract: A process for separating synthetic turf product comprising includes the consecutive steps of: (a) downsizing the synthetic turf product into a downsized turf material; (b) separating the downsized turf material by sieving into at least a first fraction substantially comprising a mixture of backing material and additional components and a second fraction substantially comprising grass fiber components; (c) separating the first fraction by specific gravity to provide a low density fraction and a high density fraction; (d) separating the second fraction by specific gravity and size by providing an airflow directed upwards in a separator configured to cause a swirling motion whereby a lighter fraction is entrained upwards in the air flow and a heavy fraction is allowed to fall downwards; and (e) collecting the low density fraction and the light fraction.

    Abstract: A process for separating synthetic turf product comprising includes the consecutive steps of: (a) downsizing the synthetic turf product into a downsized turf material; (b) separating the downsized turf material by sieving into at least a first fraction substantially comprising a mixture of backing material and additional components and a second fraction substantially comprising grass fiber components; (c) separating the first fraction by specific gravity to provide a low density fraction and a high density fraction; (d) separating the second fraction by specific gravity and size by providing an airflow directed upwards in a separator configured to cause a swirling motion whereby a lighter fraction is entrained upwards in the air flow and a heavy fraction is allowed to fall downwards; and (e) collecting the low density fraction and the light fraction.
