Overview of design standards of screw conveyors. Screw conveyors based on the principle of Archimedes screw had been applied in the ancient world and had caught researchers' interest in the mid-1900s. In 1975, an international standard for screw conveyors (ISO 1050) was published (International Organization for Standardization, …
