Moma Titanium Minerals Mine Skid Pumps

Moma mine located in Mozambique required skid mounted VSD booster pump stations to be located on the beach where they remove titanium mineral deposit. These pump stations can then be moved to a new location as required.

SUBSTATIONS FOR EXXARO GROOTEGELUK WASTE SPREADER II

Exxaro Grootegeluk mine required a second backfilling spreader machine for their operations to backfill the pit with the waste material after processing. Sandvik was awarded the contract for design, manufacture and installation.

BULK EXPLOSIVES PLANT AT SASOL SECUNDA

Sasol Nitro wanted to expand their business into bulk emulsion explosives and decided to build a plant for the manufacturing for this. The plant was built to be of modular nature for the plant to be moved if future to a new location if required.

TONGAAT HULETT STARCH AUTO CHANGEOVER

Due to the energy crisis in South Africa, Tongaat installed a generator to power their entire plant in the event of a power failure from the main grid. The national power utility wanted to buy the power from Tongaat if they had additional power or did not use their power. In order to do this, the generator had to be connected to the grid.

EWRP MINE WATER RECLAMATION AND PURIFICATION PLANT

Aveng Water/ Keyplan wanted to build the Emalahleni Water Reclamation Plant where mine water is recovered, purified and the clean water and solids recovered from the process is sold on to commercial and industrial clients.

UNILEVER FRIDGE PLANT POWER FACTOR CORRECTION PANEL

In order to gain market share, Unilever expanded their Boksburg factory by the addition of a fridge plant that forms part of their manufacturing processes. The new fridge plant would be a huge power consumer with four loads of 1000A each.

JASPER PHOTOVOLTAIC PLANT IN NORTHERN CAPE

The Jasper Solar Power Project, completed construction in October 2014 and is fully operational, playing a part in helping South Africa meet its renewable energy targets, in addition to stimulating long-term economic development and creating new jobs. The Jasper Project produces 180,000 megawatt-hours of energy annually for South African residents, enough to power approximately 80,000 homes

CONCENTRATED PHOTO VOLTAIC PLANT NEAR TOUWSRIVER

The project is a 36 MW Concentrated Photovoltaic (CPV) Solar Power plant with dual axis trackers in Touwsriver. It provides solar renewable energy directly into the national grid. It forms part of the South African Department of Energy’s Renewable Energy Independent Power Producer Procurement Programme (REIPPPP)

DESIGN STUDY FOR KUMBA SISHEN TRIPPER AUTOMATION

The Sishen Dewatering Bunkers in the DMS Plant are not automated and this leads to spillage cause by operator error. High volumes of spilled ore at the Dewatering Bunkers cause a safety risk due to the conveyor pull rope cables getting buried underneath the spillages.

STUDY FOR MAJUBA POWER STATION TRAIN OFFLOADING OPTIMISATION

ESKOM Majuba received their coal via road and rail and wanted to receive their annual coal supply via rail only. Because the existing rail yard will then become critical, the equipment had to have very high reliability and availability.

TRAVELLING LUFF AND SLEW STACKER FOR TKISSA AT EXXARO GROOTEGELUK

Exxaro Grootegeluk mine needed to increase their export coal capacity in order to meet the demands of the almost completed Medupi power station. They opted for an additional stacker to increase the stockpile capacity for export coal.

BULK SULPHUR EXPORT FACILITY AT PETRONAS RAPID PROJECT IN MALAYSIA

Sulphur is a by-product in an oil refinery and Petronas intended to store and sell the sulphur at their RAPID project in Malaysia. The sulphur will be transported by truck from the pelletising plant, imported to a stockpile and exported to a ship to sell to the market.

KUSILE POWER STATION COAL AND ASH TERRACE LIGHTING AND SMALL POWER

As part of the ever-increasing need for power, South African power giant ESKOM started to build the Kusile power station. Except for the main equipment required for a coal fired power station, lightning and small power must also be considered for the plant efficiency and safety aspect.

4 x 55kW VSD HIGH PRESSURE PANEL FOR UNDERGROUND MINING APPLICATION

To replace air drilling with hydro drilling Gold one mine required an electrical panel to drive a pump set skid for this drilling activity. The issue they faced was to regulate the pressure precisely for the drills to operate efficiently.

DISTRIBUTION BOARD FOR SAFRIPOL

This is the main distribution board for the Safripol plant that is fed by 6 transformers and the board itself then feeds a total of 24 MCC’s. The original distribution board showed signs of serious aging and the changeover methodology was a complex and dangerous activity.

SPECIALISED MCC FOR SISHEN DRUM RECLAIMER

Anglo American Sishen Iron ore mine required a new drum reclaimer for their export iron ore beds. The new machine would increase export capability of the plant and increase plant reliability as the older machines was at their end of life and the automation was outdated. The new reclaimer would also then allow for maintenance on the older machines.
