Screw conveyor systems from RUD Chains

RUD Chains Ltd, one of the world’s largest manufacturers of round steel chains, produce quality chain components and systems for a wide variety of markets and applications.

RUD’s conveyor and drive systems offer a range of product solutions to the bulk materials industry. The company design, fit and manufacture complete conveyor and drive systems, such as bucket elevators and chain conveyors for bulk materials handling. RUD’s conveyor and conveying systems for the bulk materials industry includes: scraper conveyors; drag chain conveyors, screw conveyors and apron feeders.

The transportation of bulk materials is a major challenge to ensure the availability of building materials when they are needed. System availability and reliability are often overlooked and quick solutions are used which only secures limited success. RUD have a wide range of experience across conveyor industries for fertilizer, potash, salt and cement etc.

RUD say that their screw conveyor systems are long lasting systems requiring low maintenance. Screw conveyor systems are used for horizontal, inclined and vertical transportation and typically transport fine, floury or coarse grain materials; as well as high-temperature, abrasive or slow-flowing materials.

RUD’s conveyor chains are forged, fork-sprocket chains that have been heat-treated or case-hardened. They offer a high resistance to wear which can be further increased by hard surface welding.

The drive shaft of the conveyor consists of flange or pedestal bearings; sealing is provided by grease-filled radial shaft seals. The drive station and the inspection flap can be dismantled for easy maintenance. The drive contains a standard geared motor unit, mounted on the bracket, which is attached to the side. Safety clutches can be provided to prevent overloads.

The trough consists of individual, standard-length sections with connecting flanges. Hold-down rails are recommended for most types of material that can be conveyed. These prevent the material from building up and thus the chain climbing.

RUD’s screw conveyor have been used across a range of market segments, including mining, iron and steel works, tunnel construction, quarrying, recycling and the cement industry.
