Screw Feeder TTS

Screwfeeder

The screw feeder is suitable for a wide range of grinding materials. Heavy materials such as pieces of wood, fibers or silage, as well as those high in fats or proteins, such as fish or meat meal, can be conveyed and fed into the system.

Tietjen offers the screw feeders TTS in various configurations to match the required application. The center distance between entrance and exit is at least four times the screw diameter.

In general, the robust and simple screw feeder is combined with an Air Gravity Separator series AGS for foreign body separation, simultaneously with the air inflow.

Tietjen offers a special screw for the wet process. The materials and connections used, allow the addition of different liquids to the flow of the solids.

Technical specifications
  • Designed as a single, twin, triple and quadruple screw Feeder
  • Length and inclination variable
  • Combination with a foreign body separator is possible, if required
  • Addition of liquids possible for wet grinding Systems
  • Continuous welded spirals for particularly strong auger blades
  • Precise finish, with low clearance between screw flight and trough
  • Bearings and seals can be adjusted according to the product
  • Variable manufacture of input and output for required angle or pitch

AGS for use in wood pelleting

The air - gravitational separator Series AGS is suitable for the continuous depositing of debris from all kinds of free flowing bulk goods, in particular the entry into grinding plants with the auger TTS . The construction guarantees optimal double protection from foreign bodies with a magnetic cascade and air separation of non-magnetic impurities. The housing of the AGS is very compact with only 245 mm center distance between input and output. The unit is pressure shock resistant according to the latest standard, tested in practice and certified.
