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 En Chine, bo\u00eetes \u00e0 vannes<\/strong> et laveurs \u00e0 tambour<\/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 La plupart des laveurs et \u00e9purateurs \u00e0 auge utilisent la norme sovi\u00e9tique et ont une sp\u00e9cification unique. Les \u00e9quipements de lavage chinois sont encore en phase de d\u00e9veloppement.<\/p>\n <\/p>\n Les 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 La diff\u00e9rence de structure par rapport \u00e0 la goulotte de lavage ordinaire r\u00e9side dans le fait qu'une grille est pr\u00e9vue au fond de la goulotte sur toute sa longueur et qu'un tamis \u00e0 bande fixe est pr\u00e9vu \u00e0 l'extr\u00e9mit\u00e9 de la goulotte. Une buse est pr\u00e9vue \u00e0 la t\u00eate de la goulotte (ou dans la partie sup\u00e9rieure de toute la goulotte), et lorsque le mat\u00e9riau se d\u00e9place le long de la goulotte dans le courant d'eau qui est \u00e9mis par la buse \u00e0 grande vitesse, la p\u00e9pite grossi\u00e8re glisse et tourne, de sorte que la boue est emport\u00e9e par le jet d'eau.<\/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 Les laveur \u00e0 tambour rotatif<\/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 Les laveur en spirale<\/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 En ce qui concerne le m\u00e9canisme de fonctionnement et la gamme d'applications pour la dispersion et le transport des mat\u00e9riaux, la machine \u00e0 laver \u00e0 spirale inclin\u00e9e est divis\u00e9e en deux types : une spirale (ou une spirale) et une lame. La premi\u00e8re est similaire \u00e0 un classificateur \u00e0 spirale pour le traitement des mat\u00e9riaux facilement lavables et moyennement lavables avec une taille de particule de 0 \u00e0 10 mm, et la seconde pour le traitement des mat\u00e9riaux moyennement lavables et difficilement lavables jusqu'\u00e0 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 La pratique de la production montre que la machine de lavage de l'or \u00e0 cuve inclin\u00e9e est particuli\u00e8rement efficace pour la d\u00e9sint\u00e9gration de la masse de boue visqueuse en raison de la capacit\u00e9 de frottement et d'\u00e9crasement au cours du processus de lavage. Toutefois, en raison de la limitation de la taille maximale des particules du minerai lav\u00e9, cette machine convient mieux au traitement du minerai r\u00e9fractaire contenant une grande quantit\u00e9 de minerai et beaucoup de boue. Il ne convient pas au traitement des mat\u00e9riaux fragiles, qui provoqueront un grave ph\u00e9nom\u00e8ne de boue.<\/p>\n <\/p>\n\n
