HELICOIDAL THREADS
Standard helicoidal screws
Screws with the same pitch as the diameter are considered standard. They are appropriate for a large variety of materials and for the majority of applications.
Archimedes shaftless screw
This is most appropriate for applications within the paper and cellulose industry, incinerators, meat industry and slaughterhouses, chemicals, agricultural products, and waste water treatment plants.
Conical helicoidal screwÂ
These are used in feeders to provide a uniform distribution of materials.
Double or triple pitch screw
The double or triple pitch screw is ideal for elevating liquid products.
Reduced pitch screwÂ
Recommended for sloped or vertical applications. The short pitch slows down the flow of liquefying materials.
Radial screw
Specifically designed for the transport of sticky materials. The open space between the screw and the tube prevents the build-up of material.
Multiple strip screwÂ
This type of screw consists of two or more strips of different diameters and opposing sides mounted together with rigid support bars on the same tube or axis.
One helicoid moves the material forward and another moves it backwards, ensuring an extensive and thorough mix.
Helicoid screw with cut and bend standard pitch
Excellent for heating, cooling and ventilating light substances. The bend segments lift and disperse the material.
Progressive screw
These screws are used for the extraction of free-flowing contents in hoppers.
Helicoidal screw with cuts and standard pitch
The screws are cut back at regular intervals on the exterior diameter. This allows for a mixing and shaking action of the product.
