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 ,
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 , 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."
