Submerged scraper conveyors

RUD Chains has been working very closely with well-known manufacturers of submerged scraper conveyors (SSC) since this technology was developed, and also maintains excellent contacts with end users. This of course has a positive effect on the success of further developments of our products for this field of application. A good example is our new two-part attachment (Duomount) which can be mounted in the taut chain strand.

Conveying capacities of between 5 and 50 tonnes per hour (t/h) are achieved, depending on the angle of the inclined part of the conveyor.Through puts of 50 t/h are achieved with a conveyor trough width of 2500mm. Where as high ratio geared motor drives were mainly used in the past, nowadays variable speed electromechanical or hydraulic drives are generally preferred. The normal conveying speeds lie between 0.01 and 0.05m/s, they very seldom exceed 0.07 m/s.

Components for submerged scraper

RUD components form the heart of the SSC: the conveyor chain, the chain connectors, the drive wheels, guide wheels, and the scrapers with their attachments. Toothed drive sprockets which locate internally on the chain are mainly used in submerged scraper conveyor (SSC). Occasionally, pocketed type sprockets are also used. We shall be pleased to assist you in selecting the optimum system for your conveying task.

Benefits/advantages of RUD components:

  • Highly wear-resistant to give long service life.
  • High-strength through optimal heat treatment (see max. operational forces,operational force table)
  • Self-cleaning in comparison to other systems.
  • Easy mounting and dismounting of the equipment and RUD components
  • Low-maintenance
RUD Advantages

RUD Chains offers the following priority chain systems for submerged scraper conveyors.

DUOMOUNT

1.Conveyor chain system for conveying capacities up to 50t/h. Our new two-part, mountable Duomount attachment connects the scraper to multiple chain links.

  • Available in chain dimensions 19x75 to 38x144.
  • For scraper heights up to 2.5 x the externa lwidth of the chain link
  • Bolts onto any scraper profile, and can bemounted in the taut chain strand
  • Variable scraper spacings are possible

SSRF

2. Conveyor chain system for conveying capacities upto 50t/h. Our SSRF attachment connects the scraper to multiple chain links.

  • Available in chain dimensions 19x75 to 38x144
  • For scraper heights up to 2.5 x the external width of the chain link
  • Can be welded onto any shape of scraper profile,
  • Variable scraper spacings are possible

FM

3. Conveyor chain system for conveying capacities up to 25 t/h. Our FM flange attachment connects the scraper to a single chain link

  • Available in chain dimensions 19x75 to 30x120
  • For scraper heights up to 1.8 x the external width of the chain link
  • Can be bolted into the taut chain strand
  • Variable scraper spacing possible

F

4. für kleine Förderleistungen bis 15t/h das Förderkettensystem mit einer Einliedbefestigung des Kratzers durch unseren an das Kettenglied direkt angeschweißten Mitnehmer F
