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 drive unit is typically installed on the discharge end of the system. This end is recommendable because it is the one that pulls the bulk material to the drive end. This arrangement ensures reduced wear and tear of the components of the system by ensuring that every section of the conveyor is exposed to tension generated by material being conveyed.
There are several advantages that are associated with screw conveyors. First, they are ideal for conveying dry and semi-fluid bulk materials. Also, in comparison to other conveying systems such as aeromechanical, pneumatic, and belt conveyors, auger conveyors are more cost effective. The presence of multiple discharge and inlet points allows for efficient distribution of bulk materials. Lastly, the system is usually totally enclosed from corrosive, dusty, or corrosive 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.
When the angle of inclination is increased, efficiency of the system reduces while horsepower requirements increase. Gravity caused by materials falling back is responsible for the reduced level of efficiency. Additional factors that reduce efficiency include type of conveyor system used and characteristic of material being conveyed. To achieve more efficiency in the system, the angle of inclination should be kept to the lowest.
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.
