The new Flexicon Tip-Tite drum tipper with integral flexible screw conveyor allows volumetric feeding of bulk material from drums into downstream processes free of dust.
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 45º, 60º or 90º 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 340kg and measuring 915 to 1220mm in height.
