Kang Jia Wan Revamp the auxiliary shaft hoisting system

One contradictions in two ways: on the one hand to improve the quality of domestic wire rope, using new materials and processing technology, to further improve its mechanical properties, the volume reduction in diameter t cable diameter <lo0 circumstances, can also ensure that their mechanical properties and the life; the other hand, in some mines, such as Guangdong, where the mouth of mine, lead and zinc gold Kang Jia Wan, the same used in the shaft to enhance multi-rope hoist 2250mm, long-term use in production have had 24mm of rope. Proved in practice that rolls straight (continued on page 29) Wang Jun, and other mineral-effective scientific and technological progress to improve magnetic 292.3 to increase the full recycling of iron ore tailings resources, improve metal recovery, increased precision mine output in 1985 without changing the original process the case has been transformed. After magnetic separation tailings soon after the transfer to the 2 sets of additional 1050mm × 2100mm permanent magnetic drum magnetic separator to sweep the election, receive a grade of 59 ~ 6o the second iron ore, to allow lower grade tailings 4 5 percentage points. Test in 1994, based on a secondary magnetic separation of the transformation, the second pumping iron ore concentrate to gel before the election points to the coarse ore box, to form closed loop. Following a second off the magnetic iron ore three times can be obtained after sorting the concentrate grade of 64 annual increase concentrate production 07,000 t, more than 150 million revenue. 2.4 increase in crude concentrate regrinding process re-election of I996, the Li Zhen mining companies concentrate regrinding of rough re-election process modification. The technological transformation to build a dedicated stacking only the site and a rough concentrate pool sand pump and install pump, through the pipe to the top of rough concentrate into the separator tank or the sub-ore mill side of the row of discharge Mine tank. When the need for fine grinding of crude ore concentrates to elect qualified, through the gate control of the slurry into the classifier, grit and then return to grinding ball mill, whereas the Li Zhen directly into the magnetic separator concentrator also handles the acquisition of mining company near a small selection The crude concentrate factory, so after a transformation, to deal with this part of the crude concentrate can be omitted when the crushing and grinding processing costs that some have access to qualified concentrate, thereby reducing the cost of the workshop reconstruction filter 2.5 filter to improve the magnetic seal filter tank and the mine sealed cylinder is to ensure the normal operation of filter an important part of treatment is to improve the ability to reduce loop filter an important part of the load, but also improve the filter processing an important way to reduce the cyclic loading. I995 permanent filter on the vacuum for the unique structure of the magnetic system to the mineral tank filter and motion between the magnetic seal simplified transformation to change the original rubber seal with a mechanical way, not only seal better, and significantly improve the slurry distribution, improved filtration efficiency, reducing the concentrate water is more important is the original seal in direct contact to indirect contact, minimizing friction, stopping only to avoid periodic replacement of the original production losses caused by rubber seals , fork so that filters and filter wire cloth three times increase over the life cycle, greatly reducing material consumption, and annual savings of filter wire 300kg / units, filter cloth 2X12m. / Taiwan, made a very significant benefits of using the round ball instead of 2.6 Li Zhen Cong mining companies forged steel grinding ball forged steel ball with the original, in 1992 after testing, decided to use the ball instead of forging actinide alloy ball, so that the per ton ore consumption by a 1.18kg ball down to 0.38kg. 3 Conclusion Anyang Iron and Steel Group Company Li Zhen mining companies to adhere to the concentrator plant three decades plant science and technology policy, strengthen the technology management, conducted a number of technical transformation and innovation, and create a better economic efficiency. Out of a cost-effective scientific and technological progress to improve the way mine once again proved that the \Assistant Engineer Mining Company Li Zhen {455,141 pot rule of the town of Anyang County, Henan. (Continued from page 25) diameter and the wire rope diameter ratio of less than 100 cases, enhance the operation of the system in good condition, wire rope life was significantly lower investment Kang Jia Wan rope mine life is 2 years. to resolve this. contradictions, to improve the economic benefits of mining enterprises are equally important. (3) transformation of the auxiliary shaft hoisting system is a complex system engineering, in addition to transform and elevate the system itself, but also consider the transformation of related auxiliary facilities, and after transformation and the transformation of the auxiliary set fluttering of flag hoisting system after the problems of mutual support is critical. auxiliary facilities renovation is reasonable or not, will directly cause the entire system reconstruction success and failure.
