This month’s front cover article looks at Weir Minerals, which has become a household name among the bigger players in the mining sector. The company has, in recent years, developed a keen following among smaller, independent operators in the quarrying industry with its focused range of Trio® communition products and expert aftermarket support. Weir Minerals’ strategy to support this segment includes maintaining large stockholdings of spare parts at its Johannesburg warehouse and regional branches, so that these are quickly available when required, to minimise unnecessary downtime of the plant.
JCB Construction Equipment is in the process of launching two formidable machines to market: the JS305 LC tracked excavator and the 455ZX wheeled loading shovel. These machines have been manufactured at JCB’s state-of-the-art facility in India and are designed to be easy to operate, easy to maintain and to move more material at less cost.
Quarries need to produce aggregates at the lowest cost-per-ton without affecting the overall quality of the product. To do this, operators need to take a long-term strategic view when purchasing crushing equipment and this is Weir Minerals comes in. The company is more than in tune with 21st Century crushing technology.
