  • Patent number: 5975449
    Abstract: An apparatus is provided for the pulverization of vulcanized rubber pea-size pellets. The apparatus consists of a barrel entrance, an extruder forcing section, a multiple rotor barrier section and an end discharge which presents the extrusion to a high speed wire brush-like member which shatters the extrusion into extreme small pieces. The hopper forcing section is provided with an extremely long hopper opening the design of which permits an insert which completes the barrel bore to 360 degrees. By adding inserts, the length of the forcing section is adjustable and adiabatic extrusion can be achieved. The now adjustable forcing section is followed by a section of rotor barriers, which consist of a wide top diagonal barrier crossing the extruder groove in a manner which requires all of the process material to pass through the clearance barrier top to barrel bore. The wide top barriers are provided with a set of circumferential grooves which start at capacity and end downstream at zero capacity.

  • Patent number: 5891486
    Abstract: An extrusion apparatus for processing, mixing and extruding thermoplastic and rubber materials includes a feed hopper feeding two barrier type extruders. Extrusion rotors include diagonal grooves with a barrier that has a restrictive clearance or gap relative to the extruder barrel bore. Fine material can pass through this gap, but larger material is led to a downstream end of the grooves. An abrasive barrel surface opposite the downstream end of the grooves grinds this larger material until it can pass or lead off through the smaller gap. Stationary knives located downstream of the abrasive section cut the exiting material into flakes. The barrel and barrier sections are conical and the size of the gap can be changed by relative movement between the barrel and the barriers. The extruders can operate adiabatically so that there is no change in extrusion temperature with speed and the volume of process flow.

  • Patent number: 5855929
    Abstract: An apparatus for shearing and straining polymeric process material, such a scrap tires includes a rotor and barrel. Large material pieces are feed into a hopper and the material is warmed, pressurized and transported to a rotor--barrel transfer section to initially chop the material to reduce its size. The material then passes to a rotor barrier or refining section where the material must pass over wide top barriers that extend across extrusion grooves. The barriers included multiple ridges and the barrier to bore clearance is progressively reduced as the material passes downstream. Ramp like grooves, where rejected material can be worked further, precede the barrier ridges. A rotor to barrel transfer section, having a conical barrel that can be longitudinally shifted, follows the wide top barriers, so the size to the discharged material can be regulated.
