All About Screw Conveyors

Oct 11, 2021Determine the screw design by the desired function of the screw conveyor and choose from the available options. Also, the screw design is pertinent to the drive, as there must be enough horsepower to pull material through the auger. Getting the right drive for the desired screw shape will help make sure it works as intended.
