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 has a wide range of experience across conveyor industries for fertilizer, potash, salt and cement to name a few.

RUD Screw conveyor systems are long lasting systems which requires low maintenance. Screw conveyor systems are used for horizontal, inclined and vertical transportation. They typically transport fine, floury or coarse grain materials; as well as high temperature, abrasive or slow flowing materials.

The 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 of the materials to be conveyed. These prevent the material from building up and thus the chain climbing.

RUD Screw conveyor have been used across a range of market segments from mining, iron and steel works, tunnel construction, quarrying, recycling and the cement industry to name a few. For standard or bespoke solutions from design, project management to installation or service, RUD can offer a solution.
