Welcome

In the third century B.C., the ancient mathematician and scientist Archimedes theorized the screw principle and devised the first screw conveyor system; it was known as Archimedes' screw. It consisted of a hollow cylinder with a center shaft and a spiral fixed to the inner cylinder wall and the shaft. His contemporaries used his screw conveyor design for irrigating farmland and removing water from ships.

The modern screw conveyor system developed over time between the late 1800s and the mid-1900s. Initially, it was used in the United States to increase feed and grain production on farms. It was a major component of the first feed mills, as it still is today.

As materials of construction such as abrasion-resistant alloys and stainless steels have been developed over the years, the use of screw conveyors has increased to many more industries. Recent production technology improvements include automating specific manufacturing processes to improve quality and reduce costs. The best example of this is robotic welding in the screw-making process. One of the most recent developments has been the manufacture of a shaftless screw conveyor, which utilizes a screw without the center pipe.
