Abstract
Screw conveyors consist of metal flights, each formed as a helix and mounted on a pipe or solid shaft when necessary. The helicoid type is made by cold rolling a continuous strip to form a helix of desired diameter, pitch, and thickness, to fit a given size pipe or shaft. The flights are made hard and smooth in the rolling process. The fighting is secured to the pipe by end lugs welded to the back face of the flights and by intermediate spaced welds (see figure 4.1). For more information and data on larger sizes, refer to CEMA Book No. 350.
