Classification of Gold Washing Machines<\/h2>\n
Gold washing machines can be categorized based on their material dispersion methods:<\/p>\n
1. Hydraulic Dispersion Machines<\/strong><\/p>\n 2. Mechanical Friction Machines<\/strong><\/p>\n 3. Pure Mechanical Action Machines<\/strong><\/p>\n <\/p>\n Na China, caixas de eclusa<\/strong> e lavadores trommel<\/strong> are commonly used in the processing of sand mines and gold mining vessels. In the washing operation of non-ferrous metal ore, a double-layer vibrating screen (or two single-layer vibrating screens arranged continuously) plus a spiral classifier is commonly used as washing equipment. In the washing of diamond ore, a trommel scrubber washer, a spiral washer, and a scrubbing machine with a head screen are often used.<\/p>\n In some ferrous metal beneficiation plants in the south, vibrating screens, cylindrical washing machines, and trough washing machines are commonly used. In the washing of apatite ore, various vibrating screens and trough washing machines are also used. The various vibrating screens used for washing are all shaped sieves and high-pressure water washing. Most of the cylinder washing machines are designed and manufactured according to actual needs.<\/p>\n A maior parte dos lavadores e depuradores de calhas utilizam a norma sovi\u00e9tica e t\u00eam uma \u00fanica especifica\u00e7\u00e3o. O equipamento de lavagem da China encontra-se ainda numa fase de desenvolvimento.<\/p>\n <\/p>\n O ore washing sluice box<\/a> is suitable for easy-to-wash and medium-washable ores. In China, it is mostly used for the washing of sand mines and gold ore. In actual production, it is often used in combination with a trommel scrubber or a vibrating washing screen. <\/p>\n A diferen\u00e7a em termos de estrutura em rela\u00e7\u00e3o \u00e0 calha de lavagem comum reside no facto de existir uma grelha na parte inferior de todo o comprimento da calha da comporta e de existir um crivo fixo na extremidade da calha. Existe um bocal na cabe\u00e7a da calha (ou na parte superior de toda a calha) e, quando o material se move ao longo da calha na corrente de \u00e1gua que \u00e9 emitida pelo bocal a alta velocidade, a pepita grosseira desliza e gira, de modo que o lodo \u00e9 lavado no jato.<\/p>\n In actual production, in order to strengthen the disintegration of clay-like impurities, artificial antimony ore is often used, and high-pressure water is fed into the mine with a water gun at the head of the sluice box. The fine sand and clay are separated from the coarse material by the grid at the bottom of the chute and the fixed strip at the end. The size of the grid pores and the sieve mesh are determined by the process conditions, usually 10-15 mm. The washing efficiency is related to the length and angle of the gold chute box. The unit water consumption depends on the washability of the material. Usually, the water consumption of 1 m3 of material is 10~30 m3. A=0,0098QH, kW (1-1)<\/p>\n <\/p>\n The trommel scrubber(also known as the washing trommel screen) is actually an elongated cylinder screen. A tube in which a nozzle is attached to a cylindrical sieve, water is ejected from the nozzle at a pressure of (1.96 to 3.92) x 106 Pa, and the clay-containing ore moving along the cylindrical sieve is washed.<\/p>\n O purificador de tambor rotativo<\/a> used for sieving is only suitable for the treatment of easily washed sand and gravel materials containing a small amount of clay impurities, while the cylindrical washing machine has a strong mechanical and hydraulic action, and is suitable for processing medium sizes of 200 to 300 mm. Washable and hard-to-wash ore. It is mainly used in the washing process of sandstone materials in the construction industry, some quartz sand mines, and gold mining vessels, and the washing process of brown iron ore and individual non-ferrous metal ore.<\/p>\n The structure of the rotary trommel screen is relatively simple. There are two non-porous cylinders at the feeding and discharging ends, which are supported on the idler, and the middle part is the cylinder screen. When the processing degree is not large, a single-layer cylinder sieve is sufficient. If the blockiness is large, two or more layers of the cylinder screen may be provided, and the sieve hole size is sequentially decreased from the inside to the outside. Gold trommel scrubbers are usually installed at an angle to facilitate the discharge of materials, and the inclination is generally less than 8\u00b0. The production capacity and water consumption of the cylinder washing machine depend on the washability of the ore. In terms of kinematics, the working condition of the cylinder gold washing machine is the same as that of the cylinder screen, so it can be processed according to the unit time per square meter of the sieve surface. Design and manufacture a suitable cylinder washing machine with actual data, such as water consumption. The technical data for the cylinder washers listed in Table 2 are for reference only.<\/p>\n <\/p>\n O m\u00e1quina de lavar em espiral<\/a> is available in three types: tilted, horizontal, and combined. Tilt-tank washers are the most common, horizontal, and combined because of the addition of auxiliary devices such as feedstock and dewatering products, which have not been widely used.<\/p>\n Em termos do mecanismo de funcionamento e da gama de aplica\u00e7\u00f5es para a dispers\u00e3o e transporte de materiais, a m\u00e1quina de lavar em espiral inclinada divide-se em dois tipos: uma espiral (ou uma espiral) e uma l\u00e2mina. O primeiro \u00e9 semelhante a um classificador em espiral para o tratamento de materiais facilmente lav\u00e1veis e lav\u00e1veis m\u00e9dios com um tamanho de part\u00edcula de 0 a 10 mm, e o segundo para o tratamento de materiais lav\u00e1veis m\u00e9dios e dif\u00edceis de lavar at\u00e9 100 mm.<\/p>\n The inclined blade paddle type gold washing machine is composed of a number of blade paddles, the shape and size of the blade paddle, the installation angle of the blade paddle, the overflow weir, the transmission device, the arrangement of the flushing water, and the ability to remove the slime. A variety of different models and specifications. However, in terms of mechanical structure, they are all the same, except that the blade shaft and the groove are different in size.<\/p>\n The inclined blade paddle-type gold washing machine consists of a groove body, two face-to-face rotating hollow shafts, a lower bearing, a packing water seal, a transmission device, a grit chamber, and an overflow tank. In composition, the blade paddles are made of high manganese steel and are interleaved on the hollow shaft. The apex of the blade paddle constitutes a helix, and the mounting angle of the blade paddle (usually 65\u00b0) faces the lower side of the shaft. The shaft rotates the blade to propel the ore to move toward the discharge end.<\/p>\n Feedstock and water are fed into the gold washing machine from the lower part of the tank, and about 2\/3 of the length of the tank is filled with pulp. The mud and the surface of the ore with the mineral mud adhered to it by means of the shovel, scrubbing, and flushing of the appropriate amount of high-pressure water (water pressure of 0.1~0.2 kPa) from the upper end of the tank, so that the slime is broken and separated from the ore particles to achieve the purpose of washing. The slurry and the coarse-grained material move in the opposite direction, and the washed fine mud is discharged from the overflow tank at the lower end of the tank body, and the coarse-grained material is pushed up from the blade paddle to the grit chamber for discharge. The inclination of the tank is generally 5 \u00b0 ~ 12 \u00b0.<\/p>\n In China, inclined spiral washing machines have been widely used in the washing of diamond, residual slope iron ore and manganese ore, limonite, and sand tin. The Changsha Black Metallurgical Mine Design and Research Institute has designed a sloping tank-type washing machine for the washing of difficult-to-wash limestone, dolomite, and manganese ore in the south.<\/p>\n A pr\u00e1tica de produ\u00e7\u00e3o mostra que a m\u00e1quina de lavar ouro do tipo tanque inclinado \u00e9 particularmente eficaz para a desintegra\u00e7\u00e3o da massa de lama viscosa devido \u00e0 capacidade de esfregar e espremer durante o processo de lavagem. No entanto, devido \u00e0 limita\u00e7\u00e3o da dimens\u00e3o m\u00e1xima das part\u00edculas do min\u00e9rio lavado, \u00e9 mais adequada para o tratamento de min\u00e9rio refrat\u00e1rio que contenha uma grande quantidade de min\u00e9rio e muita lama. N\u00e3o \u00e9 adequado para o tratamento de materiais fr\u00e1geis, o que causar\u00e1 um grave fen\u00f3meno de lama.<\/p>\n <\/p>\n\n
