Charlotte, NC -- Spiroflow Systems, Inc. recently introduced the new 'Rhinoveyor(TM)' range of flexible screw conveyors for abrasive materials.
Manufactured with a tough conveying tube, the 'Rhinoveyor' product line extends the scope of these versatile conveyors into applications for abrasive materials. Ultra High Molecular Weight Polyethylene (UHMWPE) had traditionally been used for the conveyor tube, but also posed a wear issue when handling moderately abrasive materials.
A key factor to the suitability of flexible screw conveyors for abrasive applications is their simplicity and lack of bearings. The conveying tube is effectively one long support while the conveyed product acts as the lubricant centralizing the rotating spiral within the tube.
Tests have confirmed that Spiroflow's new 'Rhinoveyor' conveying tubes have significantly greater life on applications beyond food, dairy and pharmaceutical products. Accordingly, Spiroflow offers a more durable conveyors for the most aggressive products such as sintered metals, PFA, pumice, sand, aggregates, silica, cement and carborundum.
Traditionally it has been recommended that flexible screw conveyors must always run full of material. Running empty can lead to excessive noise and wear. However, the nature of the new 'Rhinoveyor' conveying tubes means that running empty no longer creates the wear and noise associated with UHMWPE tubes. However, as flexible spiral conveyors are not totally self-emptying, they ideally suited for transferring material from storage to weigh hoppers or to a process but not for transferring pre-weighed batches of material where total transfer is required.
Flexible screw conveyors can, typically, carry material to a maximum distance of 60 ft, although multiple, linked units can extend to greater distances as required. The maximum throughput for the new 'Rhinoveyor' range can be has high as 5 tons/hr dependent upon the material and the angle at which it is to operate.
Spiroflow Flexible Screw Conveyors will still be available with UHMWPE conveying tubes for food, pharmaceutical, fine chemicals and other applications. UHMWPE tubes and stainless steel contact parts offer a high level of hygiene for food, dairy and pharmaceutical applications.
