Advantages of Using Screw Conveyors
3
• The trough screw is a screw conveyor principle that is used all over the world and has an
excellent price/quality ratio. Screw conveyors have a wide variety of uses.
• The term ‘low maintenance’ also applies to trough conveyors.
• There are angled variants from 0 to 90 degrees. With angles over 30 degrees, special covers are
used to prevent the product flowing back. Covers can be fitted with hinges with quick-locks and, of
course, the appropriate ATEX IECEx approved safety switches.
• Ideal for conveying dry to semi-fluid bulk materials – free flowing to sluggish.
• Cost-effective when compared to other conveying devices such as belt, pneumatic or
aeromechanical.
• Efficiently distributes bulk materials to various locations using multiple inlet and discharge points
Totally enclosed for dusty, corrosive or hazardous environments. ATEX approved for Zone 1
hazardous areas in the oil & gas industry.
• Controlled flow by varying screw pitch.
• Minimal downtime and minimum maintenance.
