Shafted Screw Conveyor

Built for Long Hauls

Shafted Screw Conveyors utilize a central solid or tubular shaft to elevate the screw flights. This reduces friction and wear, enabling longer conveyors and faster operation.

Product Data

Description

Screw conveyors are a popular choice across industries for efficient bulk material handling. But with two main designs – shafted and shaftless – selecting the right one depends on the specific material you're dealing with. Solid materials like powders, grains, and seeds are typically well-suited for shafted screw conveyors.

Shafted screw conveyors stand out for their versatility and efficiency. A key feature is the central solid or tubular shaft. This innovative design elevates the screw flighting within the trough, minimizing friction and wear. This translates to two significant benefits: the ability to handle longer conveying distances and operate at higher speeds for increased throughput. Furthermore, shafted screw conveyors eliminate the need for a wear liner inside the trough, reducing maintenance costs.
