  • Patent number: 9266114
    Abstract: A grinding machine for grinding foodstuffs, such as meat or the like, includes an orifice plate at the outlet of a grinding head. The orifice plate has collection passages that discharge a mixture of soft material and hard material through the orifice plate. A separator assembly is located downstream of the orifice plate for separating the soft material from the hard material. The separator assembly includes a tapered, perforated separator chamber that receives the mixture of soft material and hard material, in combination with a rotatable separator screw located within the separator chamber. Rotation of the separator screw functions to separate the soft material from the hard material and force the soft material through the perforations in the separator chamber. An adjustment arrangement enables the axial position of the separator screw to be adjusted within the separator chamber.

  • Patent number: 8517178
    Abstract: A separation arrangement is provided for separating between particles of different materials having different densities and comprised in a mixture of fine particles. The arrangement comprises: a solid particles feed ingress means, a solid particles pushing/pulling means and at least one mesh adapted to stop particles of the lighter material. The particles comprised in the mixture are allowed to free fall within the separation arrangement, and particles of the lighter material are being extracted away from the free falling particles by the solid particles pushing/pulling means and conveyed towards the at least one mesh. The particles of the heavier material are allowed to complete their free fall and to reach the lower part of the separation arrangement.

  • Publication number: 20090230224
    Abstract: In a facility and a method for separating glass residues from PVB-film, comminuted material is passed through several process steps, where treating with beaters (12) in a chamber (2) is effected in one of the first steps. At the discharge end (18) of the chamber there is arranged a separation, as heavy particular material can be discharged through a perforated bottom section (19) in the chamber (2). Through an air inlet (22) at the side (15) of the chamber, air is drawn in induced by a ventilator-like impeller rotor (28) drawing air in through a central opening (26) spaced apart from the bottom section (19). Thereby, light film-like materials are carried away from the heavy particles.

  • Patent number: 7204439
    Abstract: Efficient process control of a rotary breaker is dependent upon the rate at which aggregate material is delivered to the rotary breaker. An improved pre-screening apparatus provides enhanced control of the amount of undersized material allowed to bypass the rotary breaker, thus allows some control of feed rate other than the upstream mining conditions. Further, a variable speed drive mechanism allows for enhanced control of the breaking process occurring within the rotary breaker. These improvements allow for the increase in maximum feed rate to an existing rotary breaker or allows for the installation of smaller and more economical original equipment. In addition, an improved discharge mechanism is provided to increase the discharge rates of a breaker without varying size or speed of rotation. These improvements allow for advanced automated process control.

  • Patent number: 6911118
    Abstract: A pulper for producing paper pulp from waste paper containing undesired scrap particles includes a container (1) forming a chamber (4) defined by a bottom wall (5) and a cylindrical circumferential wall (6). A paper tearing member (7) is arranged in the chamber closed to the bottom wall and is rotatable in a horizontal direction of rotation about the centre axis of the cylindrical wall. The bottom wall and the circumferential wall forms a substantially circular peripheral reject chute (11) situated under the paper tearing member for collecting reject including undesired scrap particles. The reject chute extends helically in the direction of rotation of the paper tearing member from an upper end (12) of the reject chute downwardly to a lower end (13) of the reject chute. The circumferential wall (6) has a substantially cylindrical shape and extends vertically to the reject chute (11).

  • Patent number: 6588597
    Abstract: A treating system for selecting and recovering reusable materials from used composite plastics is constituted by a crushing process, a cleaning and grading process and a plastics separation process. The treating system for the composite plastics is constituted by combining the cleaning and grading process in which a mechanical impact force and a friction force are applied to the plastic crushed pieces so as to clean the plastics and form the gain size of the plastics, and the plastics separation process with using a hydrocyclone. Accordingly, a selecting accuracy of the selected and recovered plastics is significantly improved and the plastics are separated to high-purity plastics, whereby it is possible to utilize the recovered plastics as recycled materials.
