Mobile unloader - Namibia

Siwertell mobile unloader unloading bulk material to trucks

4S installed for maximum safety

Siwertell was approached by Anglo Base Metal to investigate how to unload sulphur through a safe and environment-friendly operation in the Port of Lüderitz in Namibia, which was predominately used by the fishing industry.

About

Installing a fixed unloader in the port wasn’t possible as the quay needed to be cleared after each sulphur discharge operation. Based on the client’s needs for a high unloading capacity, environment-friendly unloading and based on the sizes of ships arriving in port, the Siwertell 15 000 S was a natural choice.

Since its delivery in 2008, the Siwertell unit has been used continuously for unloading sulphur, which is employed in the mining process for the production of pure zinc.

Sulphur is explosive and corrosive and to deal with this, the Siwertell 15 000 S is equipped with a specially developed 4S MOB –Siwertell Sulphur Safety System

 

4S - Siwertell Sulphur Safety System

  • Water spray nozzles at the inlet feeder
  • Explosion venting device along the conveyors and dust collector
  • Spark and fire detectors
  • Fire extinguishing system
  • Reinforced conveyor gables
  • Automatic lubrication system
  • Temperature guards on the intermediate bearings
  • Stainless-steel screw conveyors
