Sawtooth wave jig JT sawtooth wave jig is a new type of jigs. It is one of the types of modern gravity separation equipment. New it has formed series whose use is expanded. Such type of jig uses electromagnetic stepless speed regulation which features even rotation, smooth ore current, strong adaptability to selected materials, good separation effects of medium and fine grains, and water saving. Since such jigs have large handling capacity and wide range of sorting particle sizes as well as are easy for operation and maintenance, they are mainly used to sort alluvial gold, tungsten ores, tin ores, hematite, and beach placer. Traditional jigs mostly adopt circumferential off-center drive. Their jigging pulsation curves are mostly sine waves. The ascending and descending water flow velocity and action time produced by septal movement are basically the same. These hinder the loosening of jig beds and layering of ore grain according to gravity. Therefore, the sorting ratio and recovery rate of equipment are affected. Sawtooth wave jigs are a kind of energy-saving gravity equipment development and improved on the basis of traditional jigs according to the theoretic layering law of jig beds. Their jigging pulsation curves take the shape of sawtooth waveform which gets the ascending water to travel more rapidly than the descending water. The ascending time is short while the descending time is long. The problem that the ascending and descending water flow and action time produced by sine wave and pulsation wave are the same is solved. The looseness of the bed is strengthened and suction function is alleviated so that the heavy ore grains in the minerals are able to precipitate fully and the sorting ratio ability and recovery rate of equipment are largely improved. Compared with sine wave jigs through industrial tests, the recovery rate of sawtooth wave jigs are higher than that of sine wave jigs respectively in Sn:3.01%, W:5.5%, Pb:1.63%, and Zn:2.04%. The water consumption is reduced by 30%to 40%. The area of flooring area is reduced by one-third and the stroke can be adjusted. Since electromagnetism governing-speed motors are adopted for dragging to enable the jig frequency to be steplessly regulated and their parameters reached advanced domestic level, such jigs are one of the ideal types of energy saving gravity separation equipment. 1.

Spiral classifier This classfiers suitable for dewatering,medium,drainaging amd spraying in ore clressing for medium and fine naterial wet and dry classifying in mine. Such machine is mainly used in the production flow of metal processing. According to the difference in sedimentation rate of mineral particles and mud, the particle sizes of ores with 14-325 meshes are classified. Waste mud or water for ore sand can be separated from the ores. Such machines are divided into single spiral classifiers and double spiral classifiers. Beside, they are also divided into high weir spiral classifiers and submerged spiral classifiers. If the overflow edge is higher than the center line of spiral shaft and lower than the external diameter of spiral at the overflow end, the spiral classifiers are high weir ones. If the overflow edge is higher than the center line of spiral shaft and also higher than the external diameter of spiral at the overflow end, the spiral classifiers are submerged ones. High weir classifiers are usually used for the classification with particle size of below 100 meshes. Submerged classifiers are usually used for the classification with particle size of below 200 meshes. 3.Technology parameters Model | Spiral Dia. | Spiral Speed | Output | Motor Power | Weight | Circulating Load | Overflow Quantity | Lift Lower | Drive | mm | r/min | t/24h | t/24h | kw | kw | t | High-weir single spiral classifier | FG-3 | Φ300 | 8.3-2.2 | 30-80 | 10-30 | 2.2 | 1.1 | 0.67 | FG-5 | Φ500 | 8.5-15.5 | 143-261 | 32 | 2.2 | 1.1 | 1.6 | FG-7 | Φ750 | 4.5-9.9 | 256-564 | 65 | 2.2 | 3 | 2.83 | FG-10 | Φ1000 | 3.5-7.6 | 473-1026 | 85 | 2.2 | 5.5 | 4 | FG-12 | Φ1200 | 5、6、7 | 1170-1600 | 155 | 2.2 | 5.5 | 8.54 | FG-15 | Φ1500 | 2.5、4、6 | 1140-2740 | 235 | 2.2 | 7.5 | 11.68 | FG-20 | Φ2000 | 3.6、5.5 | 3890-5940 | 400 | 3 | 11、15 | 20.45 | FG-24 | Φ2400 | 3.64 | 6800 | 580 | 3 | 15 | 25.65 | FG-30 | Φ3000 | 3.2 | 11650 | 893 | 4 | 22 | 40.9 | High-weir double spirals classifier | | 2FG-12 | Φ1200 | 5、6、7 | 2340-3200 | 310 | 2.2×2 | 5.5×2 | 15.84 | 2FG-15 | Φ1500 | 2.5、4、6 | 2280-5480 | 470 | 2.2×2 | 7.5×2 | 21.11 | 2FG-20 | Φ2000 | 3.6、5.45 | 7780-11880 | 800 | 3×2 | 22、30 | 36.34 | 2FG-24 | Φ2400 | 3.67 | 13600 | 1160 | 3×2 | 30 | 53.49 | 2FG-30 | Φ3000 | 3.2 | 23300 | 1785 | 4×2 | 40 | 73.03 | Submerged single spiral classifier | | FC-12 | Φ1200 | 2.5、4、6 | 1170-1630 | 120 | 2.2 | 7.5 | 11.1 | FC-15 | Φ1500 | 2.5、4、6 | 1140-2740 | 185 | 2.2 | 7.5 | 15.32 | FC-20 | Φ2000 | 3.6、5.5 | 3890-5940 | 320 | 3 | 11、15 | 29.056 | FC-24 | Φ2400 | 3.64 | 6800 | 455 | 4 | 18.5 | 37.267 | FC-30 | Φ3000 | 3.2 | 11650 | 705 | 4 | 22 | 46.2 | Submerged double spiral classifier | | 2FC-12 | Φ1200 | 3.8、6 | 1770-2800 | 240 | 2.2×2 | 7.5×2 | 19.61 | 2FC-15 | Φ1500 | 2.5、4、6 | 2280-5480 | 370 | 2.2×2 | 7.5×2 | 27.45 | 2FC-20 | Φ2000 | 3.6、5.5 | 7780-11880 | 640 | 3×2 | 22;30 | 50 | 2FC-24 | Φ2400 | 3.67 | 13700 | 910 | 3×2 | 30 | 53.491 | 2FC-24 | Φ2400 | 3.67 | 13700 | 910 | 4×2 | 37 | 65.283 | 2FC-30 | Φ3000 | 3.2 | 23300 | 1410 | 4×2 | 45 | 84.87 |
Note: (1) In the table, C represents submerged type, G represents high weir type, 2F represents double spiral type, and F represents single spiral type. (2) The production capacity in the table is figured out based on empirical formula according to factors such as overflow particle size, revolution speed of screw and screw diameter in ore ratio. IV. Structure Description 1. General Description This kind of machine is composed of transmission mechanism, (left, right) spiral water tank, lifting device, lower support, lubricating device, ore discharge valve, feed inlet, etc (See the attached general drawing for details). The water tank of this machine is installed obliquely. The angle of inclination is determined according to equipment configuration of equipment in the process flow. The (left, right) spirals driven by the transmission mechanism rotates in the water tank. The finely grained slurry enters the water bank from the feed inlet at one side and forms one slurry precipitation zone, whose surface area and volume depends on the value of the water tank’s inclination angle and the height of overflow edge. The spirals rotating at a low speed play a certain stirring role. After the slurry is stirred, the light and fine particles float above the surface and overflow from the overflow edge. Then they flow into the next working procedure of ore dressing. The heavy and thick particles sink into the bottom of the water tank and become return sand which is transported by the spirals to the ore discharge mouth for discharge. If ore grinding and classification are closed loop operation, the return sand discharged from the ore discharge mouth still goes into the mill for further grinding. Classifiers normally form closed loop operation together with mill. Function Diagram 1. Transmission mechanism? 2. Left spiral? 3. Right spiral? 4. Lower support? 5. Lifting Device? 6. Water tank 4. Structure Description of Main Parts ?(1) Transmission mechanism: Ф3000, Ф2400 andФ2000 classifiers consist of motor, coupling, speed reducer coupling cylinder and bevel gear pair whileФ1500 andФ1200 classifiers consist of motor, V-belt, and speed reducer cylinder gear pair. The transmission mechanism drives the rotation of spiral. (2) (Left, right) spirals: Spirals consist of hollow shaft, bracket, spiral vane, iron liner, etc. The upper ends are supported in the cross-shaft sleeves while the lower ends are supported in the lower support. Hollow shafts whose diameter is over 500mm are welded with two semicircular long steel plates so that shaft fracture due to poor welding quality caused by transverse weld can be avoided. For hollow shafts with small diameters (such as 325mm), seamless steel pipes are used. When the spirals are rotating, the spiral vanes stir the slurry slightly. The light and fine particles are discharged from the overflow weir while the heavy and thick particles are conveyed to the ore discharge mount for discharge. Anti-wear life of iron liner is very important. It needs further study. (3) Lower support: As lower support long operates submerged in the slurry, its sealing is very important. The sealing of lower support directly affect the service life of bearings. In design, it is of the multilayer cotton yarn valve-clack type packing and high-pressure grease double seal structure, and is equipped with manual dry pumps on the lubricating device. It can fill grease to the inside of bearings on a regular basis to maintain its sealing property. (4) Water tank: Water tank is welded through steel poles and all kinds of profile steel. Due to difficulty in transportation, the water tanks ofФ3000, Ф2400 andФ2000 classifiers are generally assembled and welded at the workplace. The water tank shall bear the weight of the machine itself and all load. Therefore, the design of foundation supporting the water tank is very important (the structure should be reasonable and the foundation shall be firm). To avoid the water tank becomes deformed due to improper supporting and thus affect the operation of machine, the diagram of foundation structure is attached for this machine which can serve as the reference basis for foundation design. (5) Lubricating device: To improve the lubricating conditions of machines and better the lubricating and sealing property of lower support bearings, the lubrication method of manual centralization lubrication is adopted forФ3000, Ф2400 andФ2000 classifiers. It is equipped with manual dry pumps and operating valve and can infuse grease to the insides of all bearings on a regular basis.

Cyanidation gold concentrator process Cyanidation of gold concentrator from ore or modern technology to extract gold ore the main method. Cyanidation gold extraction process include: cyanide leaching, leaching pulp washing filters, cyanide cyanide solution or slurry The extraction and finished a few basic processes such as smelting. China's gold mine existing cyanidation plant basically two types of gold extraction process used, one is a thick continuous counter-current washing machine, set with zinc powder For settling the so-called conventional gold recovery by cyanidation gold extraction process (CCD method and CCF method), the other is no filter washing, the use of activated carbon adsorption from cyanide gold recovery in the pulp-free over Cyanide carbon filter pulp process (CIP method and CIL method). Centrifugal equipment cyanidation gold extraction process by processing different materials was divided into two kinds: one is dealing with flotation gold concentrates or handling amalgamation tailings re-election Cyanidation plant. Using this process are mostly large state-owned mines. Such as Hebei Jinchangyu; Liaoning Wulong, Henan Yu Yang Village; Zhaoyuan, Metro, coke home, Sanshandao centrifugal machine . The other is dealing with mud Oxidation of ore, with all the mud mixing cyanide gold extraction plant. Such as Jilin trench; Heilongjiang unity ditch; Xinqiao gold and silver mines and other mines in Anhui. In the early 1930s have begun to use the cyanidation of gold Process. Chinkuashih gold in the 1936 Taiwan 1938, the use of cyanide - zinc replacement processes to extract gold, gold 150,000 annual two. After 60 years of the 20th century, in order to meet national Economic development, vigorously develop the mineral production of gold in some mines have intermittent mechanical agitation cyanidation gold extraction process and the continuous mixing of gold cyanidation process of gold cyanidation replace the filtration process . In 1967, the first in Shandong Zhaoyuan Gold Mountain gold plant selection and exquisite mechanical agitation to achieve a continuous production of gold cyanidation process, cyanidation of gold from 70% to 93.23%, from continuous mechanical agitation Cyanidation gold recovery machine extraction process in the country's major gold speedy promotion. 1970 Pension Jinchangyu gold cyanidation plant Wulong gold deposit in 1977 have been put into operation, then the domestic and gradually put into operation a number of machines Mechanical agitation cyanidation plant, cyanidation gold extraction process has entered a new stage of development. The continuous development of gold production and gold resources to rapidly develop, since the 1980s, the gold from the clay of high A significant increase in oxidized ore, the development of such ore mixing cyanide leaching of the whole soil studies, and unity in Heilongjiang to build a ditch on handling 500t gold ore cyanidation plant, put students in 1983 Production. Since then, the whole process of gold cyanidation mud increasingly promote the use, worked in Henan, Jilin, Hebei, Shanxi, Inner Mongolia, gold extraction plant using this method. At the same time, to address the muddy oxidation Ore in the dense solid-liquid separation filter the difficulties, in November 1979, Changchun Institute of gold began to rally ditch gold ore-free filter charcoal slurry gold extraction process, for the last two years Pilot study was successful. On this basis, in August 1984 Spirit Lake gold mine in Henan, China-made equipment designed and built using the first day of China's handling of ore CIP 50t gold extraction plant. Make China cyanidation gold extraction process took a big step forward. CIP gold extraction process to become oxidized ore processing shale rock gold mine gold on the property is one important way. Since then in Jilin, Henan, in Mongolia, Shaanxi and other places built CIP gold extraction plant. The end of 1984, Ministry of Metallurgical Industry Bureau to promote the gold of gold CIP process in our application, porting advanced foreign technology and equipment, and David McKee U.S. companies in Shaanxi Province Xitong valley gold, gold Zhangjiakou, Hebei Province, were built a daily ore processing 250t (West tong valley) and a 450t (Zhangjiakou) carbon dip Gold extraction plant. According to the survey Zhangjiakou gold reached 93.54% (1988 CIP recovery of 90.25%) of the recovery. Technological innovations based on scientific experimental research vigorously, so that China's gold production technology Technical level has improved greatly. Such as study Jinchangyu gold zinc instead of zinc wire replacement gold clay success of the exchange rate of 99.89%, significantly improved grade gold-bearing clay, zinc consumption of the original zinc wire replacement Of 2.2kg / t down to 0.6kg / t, a significant reduction in production costs. Then in Zhaoyuan, coke home, new city, promote the use of mines Wulong also made other significant effects. Low-grade oxide ore heap leaching In Dandong Hushan gold test is successful, one after another in Henan, Hebei, Liaoning, Yunnan, Hubei, Inner Mongolia, Heilongjiang, Jilin and Shaanxi provinces to promote the use of economic effect is obvious for the low Grade oxide ores opened the way for the development and utilization. According to incomplete statistics, China's current production using heap leaching gold production to reach over million ounces (in Henan Province heap leach gold production accumulated 1.3 Million ounces), but compared with developed countries, China's small-scale heap leaching, typically 1 × 103 ~ 3 × 103t / heap, million t / heap less, technically there is a big gap, 1988 Shaanxi Bai King County, two-ton heap leach gold mine large-scale field production, and achieved encouraging results (ore grade of 1.5g / t). Advanced foreign technology and equipment introduction and assimilation (such as the United States, effective thickener, double-screw Spin-mixing tank leaching, Japan's Mars pumps, belt filter, etc.), so that China's gold production at the level of equipment and technical level, there has been further improved, while also promoting our Huang Jinsheng Production equipment to high efficiency, large-scale, automated direction. Of gold in thiourea, thiosulphate of gold, pre-oxidizing bacteria leaching, pressure leaching catalyst, resin and other new science and technology Research, new advances in recent years. 1979 Changchun Gold Research Institute of gold thiourea trial is successful, and in Guangxi in 1984 built a long day dealing with mine water flotation gold concentrates 10 ~ 20t of gold shop thiourea (1987 through ministerial identification). Although other processes in the pilot study stage and is preparing to plant operation, sufficient to show China's gold extraction technology has been developed to a new water Level. | | 2:32 pm |

Evolution Jig machine Use of coal in the history of jig equipment more than 100 years, there is the 1830 manual jig, 10 (1840) appears set sieve jig, 1848, invented the continuous operation of the mechanical transmission jig, it is the piston jig prototype. As technology advances and production experience, piston jig structure and properties of a new development. In China, Shandong Xin Jia Coal Co., Ltd., Shandong Lunan is the earliest research, development, installation of complete sets of coal washing equipment, professional company. One of the sieve Jig machine under the air chamber, multi-room digital valve technology and share the slide valve cone, reliable, 70% lower failure rate, energy consumption, to meet the needs of different media sorting, increase capacity 20 % or more; structure is more reasonable, easy to transport and installation, equipment, load 30% lower; power reduced by 70% or more. Technical characteristics and performance: 1, multi-room sharing digital valve technology. 2, using the cone-shaped sliding valve, reliable, 70% lower failure rate, [1] energy consumption to meet the needs of different media sorting, increase capacity 20%. 3, a more rational structure, easy to transport and installation, equipment, load 30% lower. 4, power reduced by 70% or more. 1850 to 1864, gradually round to rectangular piston piston jig machine at the end of the flat from the previous development of a semi-circular and pyramidal. In 1875 appeared the two vertical artificial nesting jig bed, washing <10mm class at the end of coal. This jig is no discharge gate, thanks to artificial nesting bed through the sieve. 1878 using differential transmission piston jig, breaking the traditional washing cycle sine pulse, presence of non-symmetric cycle. Piston jig jig cycle adjustment difficulties, ability to adapt to the changing nature of the coal is poor. Another more serious wear and tear of moving parts, the effect often leads to washing down, development is restricted. However, this simple jig, easy to master, so there is still used. Structure of the jig, the revolutionary is 1891 to 1892 appeared Baum jig jig that is, without the piston. It pulsating jig washing with mechanical methods to produce a pulse of compressed air pulses, so that not only help expand the jig effective separation area, and washing the pulse parameters are easy to adjust to the operation of jig provide a convenient, but for improving the jig capacity and improve the layered effect created favorable conditions. The first air pulsating jig jig compared with the modern, where the difference is larger for the horizontal direction of coal flow. 1901 there has been no classification of coal sorting jig, this structure has been equipped with modern basic characteristics of jig. Washing <80mm material, the washing of the lower limit can be reached 30mm, sometimes down to 1 ~ 0.5mm. With the coal preparation plant growing type, a double screen side of the room air jig. Most of the two single jig valve into one side of the wall, into two side by side in the middle mineral jig. Both sides of the jig bed each with its own valve, or share a damper on both sides of the jig to the same room for the wind. |
