Screw Conveyor Components. Screw conveyors transport liquid or bulk materials. They have a helical screw blade, or auger, that rotates to move granular materials along the conveyor line horizontally or at a slight incline. The auger sits in a tubular housing to keep materials in the conveyor.

Screw Conveyors 8 materials, when very dry or very wet will tend to have unfavorable flowability ENGINEERING AND LAYOUT This section contains all pertinent engineering data and procedures for prescribing and specifying the important features and details of most conveyor installations. Screw Conveyor Corporation staff engineers have considerable

Horizontal Screw Conveyors. Horizontal screw conveyors are the most widely used type of screw conveyor. Used to convey bulk materials from one part of a process to another, horizontal screw conveyors are available in a wide range of sizes, lengths, configurations and materials of construction.


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. Under normal conditions the housing loading is never greater than 45%.

The drawing shows a vertical screw conveyor. The inventive screw conveyor consists of screw 1 and enveloping casing 2. On the inner surface of the housing are made of longitudinal ribs 3, placed at an angle α to the longitudinal axis of the casing is equal to the angle of ascent of the spiral auger β.

A jacketed housing is used for a variety of reasons, such as: cooling materials while conveying, maintaining product temperature while conveying, heating product while conveying, protecting equipment in a high heat atmosphere, capturing and contain fluids under a perforated trough.

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 are used in many bulk handling industries. Screw conveyors in modern industry are often used horizontally or at a slight incline as an efficient way to move semi-solid materials, including food waste, wood chips

A screw conveyor with tubular housing and reduced pitch screw (1/2 or 2/3) and larger diameter is recommended for most applications. Increasing the speed of the screw conveyor is also required. Additional horsepower is required to overcome gravity and bulk material fall back.

Screw conveyors are structurally reinforced at the ends by the use of end lugs which are welded to the non-carrying side of the flights so that material flow will not be obstructed. Screw conveyors which move material in a single direction should not be turned end-for-end unless the direction of screw rotation is reversed.

9.15.1 Screw Conveyors. Screw conveyors are used to convey bulk material from almost any position (vertical, horizontal, or at an incline) and are one of the most reliable methods of conveyance. The screw conveyor is composed of a pipe with a welded steel strip that is formed into a continuous helix. The helix is referred to as the flighting.

Design and fabrication of a screw conveyor. A screw conveyor with the housing diameter of 15.5 cm, screw diameter of 13 cm and screw shaft

Thus, the proposed device allows you to protect the bearings and the hydraulic motor from the ingress of material being transported. Screw conveyor, comprising a housing with inlet and outlet nozzles, screw auger, shaft, mounted in bearings drive and supports, characterized in that the bearings on the shafts of the screw are consistently

Vertical screw conveyors are often components in conveyor systems, attached to vats, bins, ovens, hoppers, silos and horizontal screw conveyors. They are most needed when material must be carried from a receptacle low to the ground to one that is very tall. Instead of inclined screw conveyors, which require a lot of room, vertical screw

A SCREW CONVEYOR is the generic term often used for any device which contains an internal screw or auger but it also refers to a screw which is being control fed. This means that the flow of material into the screw housing is being regulated or metered by some device such as some other piece of equipment or by means of closing off part of the inlet opening with a slide gate.
