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.
Although there are several different kinds of screw conveyors, the most commonly used is the horizontal screw conveyor. It is used in conveying bulk materials from one part of a process to another. These systems are constructed in a wide variety of sizes, lengths, configurations, and materials. Stainless steel screw conveyor systems are popular since of the materials used to make these systems is steel. The inlet of the conveyor system is usually control fed by another device such as a screw feeder, rotary airlock, gravimetric feeder, or belt conveyor.
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.
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.
Some of the industries that use shaftless conveyors include chemical, minerals, and food processing. Wastewater treatment industries also find a lot of use for these conveyors. There are several design standards for this system that producers follow to produce good systems. The standards may vary from one country to another.
