The first SDLG wheel loader sold in southern Africa by regional dealer Babcock International — an LG958L — has amassed 5 000 operating hours in extreme conditions at South African Bulk Terminals (SABT) in Durban, where 2.4 million tonnes of dry bulk is loaded and off-loaded annually. With Babcock’s support, SABT extended the bucket to a capacity of 4.9m 3 , allowing the SDLG machine to match the productivity of two alternative 9.5-tonne loaders, according to Wentzel Nel, workshop foreman at the SABT Diesel Workshop. At SABT’s round-the-clock port operations, the SDLG LG958L and its two supporting 9.5-tonne wheel loaders can load 18 000 tonnes of fluorspar onto a vessel in just three days, or 55 to 60 trucks for road transport from the port in a single 12-hour shift. SABT has also invested in a six-tonne class LG918 to shunt freight wagons at its nine-line rail yard. Shaw Controls , a Zest WEG Group company, has supplied a containerised electrical solution to supply power to drive a mill on a new gold mine in West Africa. The custom-engineered substation comprises a medium voltage (MV) WEG MVW01 variable speed drive (VSD) and a dry type phase shift transformer driving a 2 000kW, six- pole, 6.6kV squirrel cage WEG electric motor. The VSD is housed in the container while the oil-cooled transformer is housed outside of it to facilitate heat dissipation. According to Kirk Moss, medium voltage manager at Shaw Controls, specialised software interfaces with the VSD, allowing for objective detection of a frozen charge condition, while the encoder fitted to the electric motor allows monitoring of the mill angle and torque, and angle measurements make it possible to detect cascading within the mill. Metso is investing in a second melting furnace at its Isithebe foundry in South Africa, increasing its manufacturing capacity for large crusher wear parts castings used in minerals processing. The EUR3.5-million investment will ensure the availability of Metso’s heavy crusher wear parts globally. “The demand for large crusher wear parts is growing in the mining industry. With this investment, we ensure we can meet our customers’ needs. Through the renewal of the foundry, we will improve our capabilities to deliver high-quality heavy-wear parts,” says Joni Meronen, director of Mining Crusher Wears at Metso. The Isithebe plant is part of Metso’s global foundry network, consisting of foundries located in Ahmedabad, India; Přerov, the Czech Republic; Quzhou, China; and Sorocaba, Brazil. The renewed foundry will be built to follow Metso’s strict sustainability and quality principles as well as international standards. “Sustainability is of utmost importance to Metso. We are developing our operations in a safe and sustainable manner, in close dialogue with local communities,” says Thando Makhoba, director of the Isithebe foundry. The renewed foundry will be able to manufacture wear parts for the Nordberg MP2500 cone crusher, as well as for Metso and third-party primary gyratory wear parts, with full use of the latest manufacturing technologies. The first product deliveries from the new furnace are scheduled for May 2019. During the renovation project, production of castings will continue as usual in the existing facilities.
