Screw Auger Feeders THS-SHS 
    Auger Feeders for Thick Media that Cannot be Ingested Automatically
    The Putzmeister THS Feeding Equipment is meant for thick media that
  cannot be ingested automatically. Feeding equipment with self-cleaning
  augers are installed on the suction side.
The conveyed material in the feed hopper is kneaded intensively by
  augers, mixed and pressed into the cylinders to achieve a high
  volumetric efficiency factor. By this method, semisolid, earth-moist
  and visually dry-looking materials can also be conveyed into the cylinders.
The design of the augers defines the intensity of the mixture. By the
  turbulent stream in the pump and the feed line, it is intensified. A
  mixopress equipment can continuously add several additional components.
