Screw conveyors and spare parts

SCREW CONVEYORS

BASE® screw conveyors are made of painted carbon steel and are composed of an external cylindrical or bowl-shaped part and an internal spiral supported by intermediate hanger bearings, head supports and driven by gear motors. Screw conveyors are commonly made with a loading mouth and an unloading mouth of various types (flanged or cylindrical) positioned at the ends of the screw conveyor itself. At the customer’s request, they are made in various diameters and lengths.

BASE® screw conveyor is used for the transport of powders and granules of small-medium dimensions in general. Mainly used in concrete mixing plants, they guarantee a rapid and effective method for the extraction, transport and dosage of cement, ashes, calcium carbonate, sand, etc..

  • Versatility of use
  • Reliability over time
  • Ease of installation
  • Low maintenance costs

INSPECTION DOOR

Inspection doors of various sizes are made of galvanized steel, complete with rubber gasket and a clamping bracket.

They are mounted in the lower part of the screw conveyors in correspondence with the hanger bearings and the drive head, and are used to check the state of wear of the internal components and, if necessary, to carry out small repairs without having to disassemble the entire screw conveyor.

SPIRALS

They are normally made of FE510 steel specifically stretched and bended to assume the desired shapes/dimensions. The thickness at the root of the spiral is greater than at the crest in relation to the height of the spiral itself. Standard versions range from 6 mm at the root to 3 mm at the crest. Hardox coils are also available on request.

The spirals are welded on a central transmission shaft and inserted inside the pipe or the trough to complete the screw conveyors used to transport powders and small-medium sized granules in general. Mainly used in concrete batching plants, they guarantee a rapid and effective method for the extraction, transport and dosage of cement, ash, calcium carbonate, sand, etc..
