How Does a Screw Conveyor Work? Screw conveyors are volumetric conveying devices. Each revolution of the screw discharges a fixed volume of material. The purpose of a screw conveyor is to transfer product from one point to the next. Screw conveyors are always control fed at the inlet by another conveyor or metering device.
· Screw conveyor is a conveying equipment which moves the material with the help of blade rotation.If the conveyor length is too long,the screw shaft will collapse,so we need to install the hanger bearing for long shaft to avoid the excessive abrasion due to the shaft collapse,that''s why the hanger bearing is the most easily wear part.
Screw conveyors are a useful and pretty simple material handling tool for transporting bulk materials to a uniform or sloppy plane. One of their primary jobs is breaking any chunks in the material. They are used to convey various types of material. Be it dry, coarse, sluggish, thick, liquid, a screw conveyor can deal with them without a glitch.

Screw conveyors shall be guarded to prevent employee contact with turning flights. 1926.555(a)(5) Where a conveyor passes over work areas, aisles, or thoroughfares, suitable guards shall be provided to protect employees required to work below the conveyors.
· The screw conveyor drive motor should be designed for the area classification where it is located. 11. Extended screw conveyors - Extended screw conveyors, or conveyors that extend past the collector discharge opening, must have covers that are secured in such a way that they will not release dust. This means they are typically bolted shut.
Screw conveyors transfer bulk materials volumetrically and capacity is calculated in cubic feet per hour. Screw conveyor capacity is affected when the flight pitch is reduced from standard full pitch. Reducing the flight pitch reduces the capacity. For example, a 1/2 pitch screw carries 1/2 the capacity of a full pitch screw at the same level ...
When assembling loose components into a complete screw conveyor with more than one screw section, a hanger is needed to support each additional screw section to maintain proper alignment. Misalignment of screw sections can cause premature wear on coupling shafts and hanger bearings.
Classification of screw conveyors by its line of transport: a. Horizontal screw conveyor b. Angular screw conveyor c. Vertical screw conveyor. Principle of operation: The intake end of conveyor is fed with a continuous supply of particulate material.The rotating screw in the trough or pipe will lift the material by a wedging action.
