A hydraulic cylinder raises and seats the drum rim against a discharge cone, after which a second hydraulic cylinder tips the drum to an angle of 45, 60 or 90 degrees with a motion-dampening feature. At full rotation, a pneumatically-actuated slide gate valve opens and charges the conveyor, which meters the material volumetrically according to infinitely adjustable user controls.
As the flexible screw rotates, it self-centres within the tube, providing ample clearance between the screw and the tube wall to eliminate or minimise grinding. The flexible screw is top-driven beyond the point at which the material exits the conveyor, preventing contact with bearings or seals.
The conveyor transports bulk materials from sub-micron powders to large pellets, whilst the gentle rolling action of material prevents the separation of blends.
The rugged inner screw is the only moving part contacting material, resulting in reduced maintenance and increased reliability. A broad range of screws with specialised geometries is available to handle free- and non-free-flowing materials, including products that pack, cake or smear in other types of conveyors.
The unit accommodates drums from 115 to 200 litres weighing up to 340 kg and measuring 915 to 1220 mm in height.
An optional pneumatically-actuated vibrator on the discharge cone promotes complete evacuation of non-free-flowing materials.
The Drum Tipper is available constructed of carbon steel with durable industrial finishes, with material contact surfaces of stainless steel, or in all-stainless steel finished to food, dairy, pharmaceutical or industrial standards.Click here for related articles and news on Flexible Screw ConveyorsSearch for Flexible Screw Conveyor manufacturers in our Equipment Guide
