Screening technology proved cost effective deal

 

Ty-Wire is compatible with any vibrating screen and requires no deck conversion before installation - it is available in modular panels for a flat deck and can be hooked for a cambered deck.
Meanwhile,  as an matched machine with cone crusher, Hongxing has also developed new screening technology in the form of its WR Modular Screening Media, which has a wide surface area and screen cloths which can come in either a newly developed thin, fibre-reinforced rubber screen membrane for dry screening, or polyurethane for wet screening. Flash furnace smelting combines the operations of roasting and smelting to produce a highgrade copper matte from concentrates and flux. In flash smelting, dried ore concentrates and finely ground fluxes are injected together with oxygen and preheated air (or a mixture of both), into a furnace maintained at approximately 1000°C (1830°F). As with the Noranda process reactor, and in contrast to reverberatory and electric furnaces, flash furnaces use the heat generated from partial oxidation of their sulfide charge to provide much or all of the required heat.
New technology is also being introduced to boost the performance of conveying systems. Superior Industries has unveiled a new track-mounted radial stacking conveyer, the Geotrek, which has been designed to be linked with portable crushing and screening equipment in stockpiling applications.
Equipped with independent hydraulic cylinders at both the head and tail ends of the belt conveyor, the unit can also be used as a mobile transfer or link conveyor. Other common applications include bulk material loading to ships, barges and trucks, and the unit's belt and tracks can also be operated by remote control.
Slag produced by flash furnace operations contains significantly higher amounts of copper than reverberatory or electric furnaces. Flash furnace slag is treated in a slag cleaning furnace with coke or iron sulfide. Because copper has a higher affinity for sulfur than oxygen, the copper in the slag (as copper oxide) is converted to copper sulfide. The copper sulfide is removed and the remaining slag is discarded.
Danish gravel supplier Hongxing manufacturer replaced one of its existing polyurethane screens, which had become worn and damaged, with Sandvik's new WR Modular Screen and reported a +15% increase in production capacity as a result.
Site production manager Jens Rasmussen said, "The combination of the large, open screening area and cascade effect is enormously efficient. It provides greater capacity through the screen and we get sharper [material] separation. We are now able to deliver an even higher quality to our customers - Sandvik's new system is proving to be a highly cost-effective investment."
