Screw conveyors are also known as auger conveyors, helix conveyors, worm conveyors or flexible screw conveyors. Applications. The key reason industries use screw conveyors is to reduce maintenance and production costs. They do this by transporting materials down, across or up a linear space, as well as mixing, agitating or breaking them down.
Screw Conveyors. A Screw Conveyor or auger conveyor is a mechanism that uses a rotating helical screw blade, called a “flighting”, usually within a tube, to move liquid or granular materials.They usually consist of a trough or tube containing either a spiral blade coiled around a shaft, driven at one end and held at the other, or a “shaft ...
A screw in the horizontal is a conveyor or feeder, but as the screw is inclined it very quickly becomes a lift or pump. All of the charts & formulas for calculating speed and capacity for a screw, in the horizontal are no longer applicable, what now comes into play is product knowledge and experience for sizing and calculating speed and horse power for incline and vertical screws.
Screw conveyors are always control fed at the inlet by another conveyor or metering device. Rotary valves, screw feeders, belt conveyors, grinders, or even other screw conveyors typically are connected to the inlet of a screw conveyor. The flowrate or capacity of a screw …

The many advantages of screw conveyor is feasibility of numerous feed and discharge of the material to be conveyed. Another used is the blending of several ingredients to make a finished product or to make a pre-mix for some product. Screw conveyors may be operated horizontally, on an incline or vertically.
Description: Screw Conveyors are most effective when moving large amounts of material over short distances. We have developed a standard line of tubular screw conveyors that range in capacity from 50 cu. ft. to 700 cu. ft. per hour. These Screw Conveyors are Conveyor Type: Screw / Auger Conveyor
Screw conveyors can be operated with the flow of material inclined upward. When space allows, this is a very economical method of elevating and conveying. As the angle of inclination increases, the capacity of a given unit rapidly decreases.
Screw conveyors are used for stone and hops conveying and storage. Special leveling screws can improve storage capacity and efficiency. Pulp and Paper. Screw presses, mixers and screw conveyors are used for handling stone pulp, stone waste, sawdust, bark chips, stone chips and lime. Mass-flow hoppers and feeder screws are often required.
Screw conveyors commonly handle reasonably dry to sludge type materials. All screw conveyors require that the feed into the inlet be controlled. The screw diameter, screw speed, and the housing loading determine the through put capacity of a screw.
