Salt Harvesters

The first Salt Harvester build by RovD was manufactured in 1967 and had a direct take-off of 80 tons per hour (TPH). Over the years each machine grew from its predecessor and the customer’s requirements.

Today with the inclusion some advanced technologies the modern day Salt Harvester build by RovD is quiet different from its beginnings. Today the customer has a choice of highly efficient turbo-charged, twin turbo and/or super-charged diesel engines to cope with high altitude and high ambient temperatures take are common with the salt industry. The harvesters as with most mobile machinery is solely hydro-statically driven with the aid of oil coolers in high ambient temperature environments. Programmable Logic Controllers (PLC) are available on certain models or as per customer requirements. These controllers allow for automated start-up, shut-down and other routine procedures. The largest unit manufactured to-date has a direct take-off in excess 1000 TPH.

Bulk Handling equipment

The Salt Industry has presented many bulk handling challenges over the years and the following is a list of some of the equipment manufactured to achieve these ends:

  Double Discharge
  Stacking System
 

  • Stacking systems double discharge and single (arcing) systems

  • Bucket Elevators

  • Screw conveyors (all types) (Stainless Steel) • Bulk silos (S/Steel)

  • One ton and 50 kg bagging systems (load cell weigh off) on ton bulk bags

  • Logic controlled multi screw conveyor systems from storage silo’s to centralised bag off and packaging

  • Vibrating hoppers with high angle belt conveyor feed to factory

  • Belt conveyors with trippers for bags to bulk stores

  • Mobile belt conveyors (Diesel engine/hydraulic) operating in tandem across soft salt pans, discharging to trailers by mobile elevator unit.

  • Pan flattening machine (track laying) for levelling and compacting soft pans

  • Large bore pipelines for sea water intake complete with vacuum priming systems

  • Installation of sea pumps and ancillary pipework

  • Installation of large vibrating screens for dry salt with special suspension structures

Plant and Process equipment

Not only has RovD manufactured and commissioned various process equipment, but RovD has also been involved in some innovative designs that have improved the way Salt has been processed. The following is a list of some of the equipment manufactured:

  • Manufacture of roller crushing equipment

  • Clarifloculator drives and plough systems

  • Raw salt screw washing machines complete with rotating/vibrating dewatering screens or centrifuges. Semi mobile with electric drives or Diesel driven hydraulic drive

  • Rotary sterilising kilns and specialised combustion chambers to enable diesel or paraffin to be used with products of combustion directly on to the salt

  • Manufacture of various types of dry and wet Iodate application and mixing system
