The feeding of extruders with blend of two mixture-forming materials, in which one of the material from a supply tank (3) is transferred to the extruder by filling line (7) and other material is delivered to the transferred material flow. The material is a mixture of calcite-filled PVC and a master batch containing a stabilizer and a lubricant, which are batch-wisely delivered from a transport container to the supply tank through an upwardly slanted feeding screw conveyor. The material delivered to the transferred material flow is a reclaimed product and micro granulates/dye flakes. The feeding of extruders with blend of two mixture-forming materials, in which one of the material from a supply tank (3) is transferred to the extruder by filling line (7) and other material is delivered to the transferred material flow. The material is a mixture of calcite-filled PVC and a master batch containing a stabilizer and a lubricant, which are batch-wisely delivered from a transport container to the supply tank through an upwardly slanted feeding screw conveyor. The material delivered to the transferred material flow is a reclaimed product and micro granulates/dye flakes. The blend is continuously mixed in a mixing line under reduced/constant pressure before its entry into the feeding end of the extruder. The PVC is filled with 50 weight parts of chalk per 100 weight parts of the PVC. The dye and the reclaimed product are delivered to the PVC at a quantity of 0.1-1.0 weight parts per 100 weight parts of the PVC and at a quantity 5 weight parts per 100 weight parts of the PVC respectively. An INDEPENDENT CLAIM is included for a device for feeding an extruder with a blend of two mixture-forming materials. |
