Weir Minerals launch new sand wash plant

Company introduces robust and reliable sand washing solution using best-in-class Weir Minerals equipment

DRAWING on their long experience in the sand and aggregate industry, Weir Minerals have introduced a complete sand washing solution that is said to produce more saleable product than conventional sand screw plants, with fewer moving parts and an optimized process that produces a drier, higher-quality product with less fines.

The solution has already proven effective for Coimbatore Minerals in Tamil Nadu, India, where a custom-built Weir Minerals sand wash plant reduced their total cost of ownership by 51%, whilst offering a 23% reduction in fines that helped their product consistently meet the industry’s high standards for a saleable product.

‘We know the most important thing for quarry operators in washing is recovering as much sand as possible to maximize their sales, which is why we’ve designed an integrated solution with a hydrocyclone that can deliver greater recovery than sand screws,’ said Bruce Cooke, Weir Minerals’ global product manager for sand wash plants.

‘In addition, every component of the sand wash plant has been selected by our expert engineers for its long-service life, interoperability and ease of maintenance,’ he added.

The compact solution features a range of Weir Minerals equipment designed for high efficiency in sand and aggregate applications, including Warman WGR pumps, Cavex hydrocyclones, Enduron dewatering screens, Linatex hoses and Isogate knife-gate valves.

The Warman WGR pump combines superior hydraulic design with an adjustable impeller, long bearing life and a simplified wet end, making replacement predictable and cost-effective, whilst precision-moulded Linatex premium rubber is used to line wear zones throughout the plant, owing to its proven wear performance in wet sand applications in operations around the world.

Cavex hydrocyclones provide exceptional classification efficiency thanks to their unique 360° laminar spiral, which delivers more saleable product than a sand screw solution, whilst Enduron dewatering screens reliably separate product with a high degree of efficiency and robust Isogate knife-gate valves contribute to the plant’s straightforward maintenance.

‘For the new sand wash plant, we focused on making it quick and easy for quarry operators to get up and running,’ commented Surendra Menon, president of Weir Minerals India.

‘Its straightforward design means it can be assembled in just two days, whilst its compact skids make it easy to drag into any operation. Efficient, reliable and easily integrated into flowsheets, we think the plant is a game-changer for quarry owners.’

Weir Minerals sand wash plants are available in all regions and, like all Weir Minerals equipment, are supported by the company’s global service network, which includes more than 150 locations each with spare parts and expert maintenance support.
