Screw conveyors – Spirotech Group design, manufacture and supply complete screw conveyor systems
Spirotech Group has been designing,manufacturing and delivering screw conveyors since the company’s inception in 1979. As one of its foremost products Spirotech has strived to deliver a better quality product and service than its many competitors. With the recent acquisition of a flight press system that produces full 360 degree flights up to 1600mm diameter, and with a new York-based spares and service centre on call 24/7, Spirotech now supply screw conveyors to major players worldwide.
Tailor-made screw conveyors by Spirotech
The Spirotech Design & Production team have extensive knowledge with regard to the characteristics of materials and their properties, and design efficient and cost-effective screw conveyors to suit individual requirements. Ideal for both light and heavy usage, Spirotech’s screw conveyor systems are tailor-made for many types of product processing across a wide variety of markets. High build quality coupled with Spirotech’s own commitment to high standards of production ensure a top quality experience for its customers – from initial consultations through to delivering the final product.
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, aggregates, cereal grains, animal feed, boiler ash, meat and bone meal, municipal solid waste, and many others. The first type of screw conveyor was the Archimedes’ screw, used since ancient times to pump irrigation water.
They usually consist of a trough or tube containing either a spiral blade coiled around a shaft, driven at one end and held at the other, or a “shaftless spiral“, driven at one end and free at the other. The rate of volume transfer is proportional to the rotation rate of the shaft. In industrial control applications the device is often used as a variable rate feeder by varying the rotation rate of the shaft to deliver a measured rate or quantity of material into a process.
Screw conveyors can be operated with the flow of material inclined upward. When space allows, this is a very economical method of elevating and conveying. As the angle of inclination increases, the capacity of a given unit rapidly decreases.
The rotating part of the conveyor is sometimes called simply an auger.
