In the re-election plant, the shaker is the most widely used and efficient sorting equipment for sorting fine ore. Shaker beneficiation can not only be used as an independent beneficiation method, but it is often combined with jigging, flotation, magnetic separation and mineral processing equipment such as centrifugal concentrators, spiral concentrators and belt chutes. Shaker has been widely used tungsten, tin, Tam, lozenges and other rare metals and precious metal ores and sorting, in addition, when sorting iron, manganese ore is also widely used. Before the flotation method appeared, it was also used for the selection of non-ferrous metal ore. During the re-election of tungsten, it is estimated that about 30%-V80% of the concentrate is obtained by shaker sorting.
The particle size of the shaker is generally 2^-0. 037 mm when the tungsten and tin are selected, but the lower limit of the particle size of the slime shaker can be 0.0119 mm. In production practice, because the shaker is used in conjunction with other equipment, it is often used to recover fine minerals above 37 microns.
The main advantages of shaker beneficiation are: 1 The enrichment ratio of beneficiation is very high, up to 300 times; 2, after one sorting, the final concentrate and abandoned tailings can be obtained; 3 sometimes multiple products can be obtained at the same time as needed. 4 minerals on the bed surface is obvious, so it is convenient to observe, adjust and pick up.
The main disadvantage of shaker beneficiation is the low processing capacity per unit area and the large area occupied by the plant. 5å¨/å°æ—¶å·¦å³ã€‚ The maximum capacity of the coarse sand, the surface of the bed is not more than 5 tons / hour;
