Working Principle

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.

FAQ

Quotation of factors

Material bulk density, mesh size(length & angle for conveying series) & ideal capacity for proper type, granularity distribution is recommended. product material requirement (carbon steel Q235A, stainless steel SUS304 or SUS316,etc.) Voltage & Frequency(Hz) is also needed for a precise quotation.

Delivery time
7 to 15 days for general series products, meanwhile, batches products & customized products would need 30 days to 60 days based on different situations.

Quality of products
