Flexible Spiral Conveyors with a tube having a diameter from 40 mm – 140 mm suitable for the characteristics of the material being transported. We produce also shaftless screw conveyors. Load capacity from 120 kg/h-10,000 kg/h Real load capacity also depends on the following factors:

  • Flexible Helix Conveyor rotation speed;
  • Pick up inclination;
  • Fluency of material;
  • Type of pick up: suitably shaped hopper, silo, barrel, heap.

The flexible screws, also known as flexible screw conveyors or even conveyors in general, are systems widely used in the food, chemical, pharmaceutical and plastics industries for conveying; they provide equal efficacy for powders, granules, ground materials, and mixtures.

FLEXIBLE SCREW CONVEYORS

Flexible screw conveyors systems are capable of:Powder Conveying Systems

  • Preventing demixing, during conveyance, of mixed and batched products;
  • Homogenizing during transportation;
  • Conveying several combinations;
  • Preventing pollution because tightly sealed and mechanical;
  • Quiet operation at the workplace;
  • Being introduced into existing systems thanks to the flexible screw and to the flexible hose;
  • Loading and unloading at any point of the line;
  • Overcoming significant vertical drops and covering substantial distances.

Equipment for explosive atmospheres (ATEX)

Upon request either the flexible screw conveyor either shaftless screw conveyor can be designed and built in conformity to ATEX Directive 4/9/CE for Zone 2-22 / Zone 1-21

For capacity in kg/h multiply for bulk density of your product. The transportation potentialities depend on several variables and therefore the tabulated values are understood as approximate. It is assumed pick-up will be performed with:

  • Transported material: free flowing granular powder;
  • Apparent specific weight 1 kg/dm³;
  • Initial pick-up length having inclination α = 30°;
  • Rotary spiral with 580 rpm (except MAR 140) (930 rpm applications are also possible).
