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.
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.
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.
