The Linatex-lined plant produces more saleable product than conventional sand screw plants, with fewer moving parts and an optimised process that produces a drier, higher quality product with fewer fines.
The solution is already said to have proven effective at sites like Coimbatore Minerals in Tamil Nadu, India. There, a custom-built Weir Minerals Sand Wash Plant reduced site management’s total cost of ownership by a claimed 51%, while also offering a 23% reduction in fines, helping their product meet high industry standards.
“We know the most important thing for quarry operators in washing is recovering as much sand as possible to maximise their sales. This is why we’ve designed an integrated solution for washing their product, with a hydrocyclone which can deliver greater recovery than sand screws. In addition, every component has been selected by our expert engineers for its long service life, interoperability and ease of maintenance.” says Bruce Cooke, Weir Minerals global product manager - Sand Wash Plants.
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 is the pump of choice in the sand extraction industry, combining top-of-the-line hydraulic design with an adjustable impeller, long bearing life and a simplified wet end, making replacement predictable and cost effective.
Precision-moulded and lined, Linatex premium rubber is used for wear zones throughout the plant due 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, delivering more saleable product than a sand screw solution would.
Enduron dewatering screens reliably separate product with a high degree of efficiency, while 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. Its straightforward design means it can be assembled in just two days while 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,” says Surendra Menon, president, Weir Minerals India.
Like all Weir Minerals equipment, the sand wash plant is supported by Weir Minerals’ highly competitive global service network that includes more than 150 locations each with spare parts and expert maintenance support.
Weir Minerals sand wash plants are now available for customers in all regions.
