Choosing a Screw Conveyor for Your Tough Material
For handling such a material, choose a vapor- and dust-tight screw conveyor designed to withstand explosion pressures. The conveyor's flight-tip-to-trough clearance should be large enough to prevent metal-to-metal contact during conveying. The conveyor can also be equipped with a trough and screw made of dissimilar metals, which are less ...
