Weir Minerals has expanded its coal dewatering solutions with the launch of the Aspir™ WFH1730 jumbo horizontal basket fine coal dewatering centrifuge.
The new Aspir™ WFH1730 jumbo centrifuge is specifically engineered and sized to process 100tph of fine coal product, with centrifuge utilising a proven scroll/basket design, combined with high quality wear components, and maintenance friendly wet end, specifically designed to handle varying feed densities.
Paul Jerks, Product Manager for Weir Minerals Aspir™, explained that the design of the inlet/effluent arrangement was such that when the centrifuge was presented with a dilute feed, the jumbo centrifuged the effluent directly out of the bottom of the machine eliminating any potential of effluent splashing over into the product chamber. The product chamber is further protected by a labyrinth seal between the effluent and product chamber.
Central to the Aspir™ range are the coarse and fine coal centrifuges are expertly engineered to deliver outstanding performance and availability in the most arduous coal dewatering applications.
“The WFH 1730 jumbo centrifuge is the world’s first high capacity horizontal fine coal dewatering centrifuge designed around proven principles, such as G-force and basket angle. This ensures maximum throughput with highest dewatering efficiency at minimal operating costs,” said Mr Jerks.
“Simply put, the Aspir™ WFH 1730 jumbo centrifuge’s robust design works smarter and longer than other centrifuges on the market to optimise your coal processing capability.”
The Aspir™ WFH 1730 jumbo centrifuge features a cyclone inlet (patent pending) that aids in the process of separating solids and water prior to the fine product being introduced to the basket. Additionally, the inlet assists in bringing the product up to basket speed, reducing coal breakage which increases fines and moisture content.
The Aspir™ WHF 1730 jumbo centrifuge is designed to process a genuine 100tph of fine coal with the ease of maintenance advantages of a horizontal basket.
The Aspir™ WHF 1730 jumbo centrifuge has a horizontal orientation that allows for a reduced number of gears and shafts within the centrifuge and offers in situ replacement of the modular drive assembly. Together with the ceramic lined working faces, and hinged effluent chamber, it provides ample clearance of parts delivering unfettered access to wet end components, making it one of the most technologically advanced fine coal dewatering centrifuges and one of the easiest to maintain.
The horizontal basket design with its hinged door arrangement and container lock-securing mechanism makes for quick and easy access to the wet end for any maintenance inspections. Once open, it provides direct access to the basket and high capacity scroll.
“The horizontal basket design, unlike a Vertical basket centrifuge, uses centrifugal force and gravity to its advantage in that effluent naturally wants to pass through the basket aperture thereby enhancing the centrifuge’s dewatering effect,” added Mr Jerks.
