Screw conveyors primarily consist of a rotating screw shaft that is installed within a trough. As the screw shaft rotates, the material moves linearly. They can be designed to provide horizontal, vertical, and inclined travel paths. Several types of screw conveyors are designated to handle a specific material behavior.

Once it has been determined that a Screw Conveyor will best fit your application, and the type of screw conveyor you will use (shafted or shaftless), a calculation will be completed to specify the horsepower that will be needed to meet the needs of the application. Simply put, horsepower is a measure of the rate at which work is done.

The horsepower required to drive a screw conveyor is called Total Shaft Horsepower, or TSHP. TSHP is a function of the characteristics of the bulk material being conveyed and the friction inherent in the screw conveyor. It is very important to design a screw conveyor with sufficient horsepower in order to prevent downtime and loss of production.

INCLINED CONVEYORS SPIRAC U-trough and OK-trough conveyors are both suitable for material transport up an incline. These can be hopper fed up to approximately 45 degrees, or force fed at steeper inclines. Features and benefits: Typically U-trough arrangement up to 30 degrees, depending on material. OK-trough 35-90 degrees.

transfer screw design allows fluid media to move inside a jacketed trough, hollow flights and core-buster pipe. Another good solution for limited space is the shaftless screw conveyor that doesn't require end-bearings. Additionally, live-bottom or multi-screw conveyors can combine hoppers and metering equipment into one.

In that case, theoretically a short horizontal shafted or shaftless screw conveyor could be designed at trough fill rate. Most conveyor manufacturers however, recommend limiting trough fill rate to 45% maximum even at ideal cases (non-submerged apps) for several reasons, primarily as a safety factor for multiple design variables. Shafted ...

Screw conveyors must be fabricated from abrasion resistant alloys. Typical materials of construction are AR235, AR400, AR500, TriBraze or chromium carbide overlay. These materials are harder and tougher than A36 carbon steel for resisting abrasion. The carrying face of the screw may be hardsurfaced with a weld-on hardsurfacing material.
