A screw conveyor is a mechanism used in many industries to move granular and liquid materials for various processes. The name auger conveyor is sometimes used to refer to them. The system was invented several years ago by a Greek scientist named Archimedes. Today, the machine enjoys a lot of use and popularity in a wide range of industrial and commercial applications.
The most common screw conveyor is the horizontal one, even though there exists a number of other screw conveyors. This one is used to horizontally convey bulk materials from a section of an industrial process to another. The systems are made in a number of configurations, sizes, lengths and materials. Stainless steel screw conveyor is common because steel is among the materials used in making these systems. The rotary air lock, gravimetric feeder, screw feeder or the conveyor belt can be used for the inlet of conveyor system.
The discharge side is the conventional point of installation of the drive unit. The reason that this end is recommended is because it is the one responsible for displacing bulk material to the drive end. Reduced tear and wear is achieved using this arrangement by ensuring that every part of the conveyor experiences the same tension produced by the commodity being moved.
Screw conveyors come with a number of merits. First and foremost, they are best suited for moving semi fluid and dry bulk commodities. Furthermore, screw conveyors are more effective in light of cost when compared to the pneumatic, belt conveyors and aeromechanical. Efficient placement of bulk items is achieved by the existence of multiple inlets and outlets. Finally, the systems are completely protected from corrosive or dusty environments
Inclined auger conveyors are alternative types of the screw conveyors. The system typically operates at angles from the horizontal. The angles between the system and the horizontal line could range from a few degrees to 45 degrees. The systems cannot be referred to as inclined conveyors if the angle of inclination exceeds 45 degrees. In such a case, they are referred to as vertical conveyors. The KWS engineering guide for the constructing vertical conveyors must be followed in that case.
Increasing the angle of inclination usually increases the horsepower requirements of the system, while reducing the level of efficiency. The reduction in efficiency is caused by the effects of gravity as bulk materials fall back. Other factors that affect efficiency include characteristics of the materials being conveyed and type of conveyor in use. It is often recommendable to keep the angle of inclination to the lowest level possible.
Another kind of conveying system is the shaftless screw conveyor. This system discharges bulk material from centrifuges, mixers, or filter presses. It is used to convey materials that would otherwise be hard to convey on other models of conveyors. It is also effective at conveying bulk material that have high amounts of moisture content. With good design, this system does not clog.
Shaftless conveyors are in wide use in many industries including chemical, food, and minerals processing plants. Also, wastewater treatment industries have use for shaftless conveyors. Producers are required to adhere to the various design standards that exist in the market for these systems. Each country tends to have its own standards.
