Screw conveyors

Rigid - but still flexible! … It is under this heading that tried and trusted Wutra screws are supplied for use, even in most difficult conditions.

Being rigid gives a high degree of durability, even in abrasive and corrosive environments as well as extreme temperatures. Flexibility means the great diversity and modular construction of the Wutra conveyors.

  • Robust construction to withstand the heaviest loads over long periods of time
  • Flexible system integration using 3D planning
  • Short delivery periods due to standardised modular constructions, as far as possible
  • Conveyor lengths up to 60 m
  • Conveyor capacity up to 800 m³/h

Individual system solutions

For decades, Wutra screw conveyors have been used to transport the widest range of bulk materials under the hardest environmental conditions. Wutra screw conveyors are designed as a modular system with many variants to suit the task in hand, planned, produced and assembled for the purpose.

  • Closed and dust-tight transportation
  • Optimal drive dimensioning
  • Product and application specific seal configuration for any assembly position
  • Rapid cleaning using large and easily accessible inspection openings
  • Certification according Atex - Directive 2014/34/ EU
  • Built for 24 hour operation

Dosing, weighing, mixing

Consistently exact feed and mixing of bulk materials is a pre-condition of the highest product quality. Single and double screws with paddles or shaftless screws are used for continuous or non-continuous mixing operations. Paddle mixing screws create the best mixing performance and the most homogenous result.

  • High dosing accuracy
  • Low pulsation of product flow through dosing star and double-threaded screw flights
  • Quick-cleaning system for frequent product change
  • Double paddle screw mixers for continuous and non-continuous operation
  • High mixing qualities
  • Gentle mixing
  • Defined retention periods

Feeding and discharging

Discharge screw conveyors ensure that difficult bulk materials flow continuously from silos and hoppers. The screw shafts are particularly robust to withstand the pressure of the materials. Activating large cross-sections means that bridge formation can effectively be avoided in silos.

Inclined screw conveyors are preferably filled with Wutra stuffing screws to achieve optimum performance. Wutra stuffing screws can also be used in pressurised processes. The compact construction makes it suitable for several applications where there is a lack of space.

  • Mass flows in silos
  • High break moments
  • Geregelter Produktaustrag
  • Defined product discharge
  • Constant volume stream
  • Safer product feed in vertical screw conveyor

Conveying and other process steps

A screw conveyor may be used for several associated process steps joined together to form one system.

There are many possible configurations and variations to ensure that the required process phases can be implemented. The guaranteed process parameters can be set partially using the corresponding preliminary tests.

  • Dosing
  • Mixing
  • Separating and sieving
  • Stuffing
  • Discharging
  • Washing
  • Cooling and heating
