Choosing a Screw Conveyor for Your Tough Material
To handle a toxic material, choose a screw conveyor with a vaporand dusttight housing. The conveyor should have extremely tight shaft seals, such as gaspurged seals or flangetype gland seals with multiple rings of packing material. Also use a dust control system that captures and removes toxic fumes and dust at the conveyor discharge.
