<\/a><\/figure>\n<\/div>\n\n\n\u201cOur local screening media manufacturing operations at Crown Mines in Gauteng align with our global procurement focus on sourcing raw materials,\u201d says Steinmann. \u201cThis makes it possible to use our own unique material formulations to manufacture world class screening media products.\u201d<\/p>\n\n\n\n
Together with its specialised materials, Sandvik Rock Processing also optimises each screening media panel design to maximise wear life and efficiency, he says. The company has developed panel load limit calculations to ensure structural integrity while avoiding over-designing.<\/p>\n\n\n
<\/a><\/figure>\n<\/div>\n\n\n\u201cOptimising our screening media allows us to streamline our screen designs, leading to overall mass and cost reductions,\u201d he explains. \u201cAs an essential part of our vibrating equipment offering, our screening media offer optimal performance at the lowest overall cost.\u201d<\/p>\n\n\n\n
He notes that the open-case polyurethane dispensing machine at Sandvik Rock Processing\u2019s Crown Mines facility is specially designed in a flexible machine configuration \u2013 to produce a range of polyurethane products of the highest quality and at the most efficient rate.<\/p>\n\n\n
<\/a><\/figure>\n<\/div>\n\n\n\u201cVarious non-standard polyurethane parts can be made in an open-mould casting process,\u201d says Steinmann. \u201cThis is achieved by placing moulds on a heated casting table, and then filling them with hot-coat polyurethane mixing systems using the dispenser casting hose.\u201d<\/p>\n\n\n\n
This allows the machine to produce parts such as non-standard-sized screening panels and sideliners, wedges, discharge liners and protector liners \u2013 providing flexibility in meeting a diverse range of products even at low volumes. He highlights that Sandvik Rock Processing regards innovation as a strategic cornerstone, using the discrete element method (DEM), for instance, to analyse material flow and optimise the selection of aperture size and type for each application.<\/p>\n\n\n\n
\u201cOur screening philosophy is that the optimal design and selection of screening media panel should cater to the distinctive characteristics of the ore being treated,\u201d he explains. \u201cThis in turn needs to align with the vibrating machine\u2019s physical and dynamic parameters. It is our strong portfolio in both vibrating screen equipment and screening media that puts us in the best position to provide tested solutions to the market.\u201d<\/p>\n\n\n
