subject: HPC hydraulic cone crusher practice case studies and applications [print this page] Mineral processing materials is the key to breaking process, especially the broken low energy utilization. Therefore, reducing energy consumption broken, with crushing energy efficient equipment is the key.
In recent years, China's major crusher, flour mill and sand making R & D base in Shanghai Machinery Co., the world production of HPC State High-Efficiency Hydraulic Cone Crusher as dressing the broken, the crushing equipment more widely in use. So far, there are thousands of units throughout the country HPC High-efficiency hydraulic cone crusher in the iron ore, nonferrous metal mines, power plants and large stones factory civil construction materials used, the crushed mineral powder in the 0 ~ 5mm mineral content was significantly higher than China-made old-fashioned spring cone crusher. Therefore, our more efficient concentrator using HPC-based alternative to hydraulic cone crusher spring cone crusher made old-fashioned, without changing the crushing process, with minimum investment to achieve "less more broken ground," a significant reduction in grain crushing products degrees, significantly improves the efficiency of ball mill and concentrator production capacity and achieved better economies of scale.
Gold mine in Liaoning Paishanlou start construction in September 1996, July 1, 1997 pre-production, ore processing capacity to reach the end of 1200t / d in the design of the scale, open pit ore from the maximum fragmentation 700mm, mineral density of 2.71 t / m3, universal hardness f = 10 ~ 12, but the ore cleavage develops a refractory hard grinding. Select plants broken by three-stage process for a closed, two closed-circuit grinding, grinding fineness - 200 projects 85%, C IL-wide mud activated carbon adsorption of gold cyanide production process.
Gold deposit in Liaoning Paishanlou early use in China HPC hydraulic cone crusher is one of mine. The end of 1997, as the world gold prices, business by 1200t / d production scale organizations, selected plant loss can not recover the investment. Capacity must be increased to 1500t / d or more, enterprises can survive and develop. However, because of the crushing equipment PY1750 cylinder Hydraulic Cone Crusher and the row of mine mouth capacity constraints, is difficult for enterprises to expand production. Flow test results in 1997, when the processing of primary ore, the ore port in the broken row of 25mm, mine mouth crushing row 9mm, 15mm 30mm mesh under the conditions of crushing up to 178% circulating load rate, degree of very coarse (- 12 mm size fraction accounted for 72%, 12 ~ 20mm, 28%), severe impact grinding capacity, while the follow-up operation has the potential to increase production capacity. Broken for the expansion of production capacity bottlenecks. April 1998, Paishanlou gold crushing system on a technical transformation, adding a buffer of about 10 tons of ore storage capacity and speed conveyor, using on-site production of steel base, on the basis of the original installation of crushing HPC315 cone crusher, vibrating screen mesh will be changed to 10 mm 12 mm.
Through technological transformation, broken product size reached -6. 6 mm accounted for 80%, - 5 mm of the powder ore content of 60 ~ 70%, ore dressing plant daily processing capacity and stability than in the 1500t, monthly processing ore from the transformation up to the front of 26456t 48450t. Increase in production after only six months to recover the costs of reconstruction, economic efficiency has been remarkable. Transformation before and after the technical and economic.
State Machine Co., Ltd. Shanghai World production of HPC hydraulic cone crusher with high-performance crushing chamber type and the successful combination of high breakage frequency, making efficient HPC hydraulic cone crusher with greater capacity, but also thanks to the principle of laminated broken, so broken Multi-cubic structure to a great extent to reduce the pin sheet material. HPC efficiency hydraulic cone crusher machine structure is simple, easy to operate, maintain, convenient nesting population adjustment, repair saves time and effort when, in particular the fast liner easy to change, reducing downtime.
HPC hydraulic cone crusher has been widely used in mining, cement, sand and gravel industry, used in fine crushing pressure of 350 MPa in the following range of mining the rock, such as iron ore, nonferrous ore, basalt, granite stone, limestone, sandstone, pebbles and so on.
