FLEXIBLE SCREW CONVEYOR

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

The flexible screw conveyors are made with a tube having a diameter from 40 mm - 110 mm suitable for the characteristics of the material being transported. A flexible screw conveyor, also known as a spiral conveyor, screw conveyor, helix conveyor or centerless auger conveyor, consists of a spring steel or stainless steel, flexible screw that is enclosed in a flexible or rigid plastic tube, or a rigid steel tube, and driven by an electric motor normally located at the discharge end of the conveyor.

Load capacity from 120 kg/h-10,000 kg/h

Real load capacity also depends on the following factors:

1. Spiral rotation speed;

2. Pick up inclination;

3. Fluency of material;

4. Type of pick up: suitably shaped hopper, silo, barrel, heap.

This conveying system is capable of:

• 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 because it is flexible;

• Loading and unloading at any point of the line;

• Overcoming significant vertical drops and covering substantial distances.

Upon request the system can be designed and built in conformity to ATEX Directive 94/9/CE for Zone 2-22 / Zone 1-21

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 (excepr MAR 140) (930 rpm applications are also possible).
For having 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.
