Application of 6s shaker in tungsten ore beneficiation

The 6S shaking table for tungsten ore beneficiation plant mostly uses an eccentric elbow-type shaker. 6S shaking table is one of the re-selection equipment for fine-grained ore. It is widely used for the separation of tungsten tin niobium and other rare metals and precious metals. It is also used for the separation of iron and manganese ore. In recent years, it has also been reported that the iron minerals in the tailings of magnetic separation plants and the selection of non-metallic minerals such as mica are recovered by shakers. The selection process of the shaking table is that the flushing water fed from the water supply tank flows in a uniform thin layer in the direction of the inclined surface of the bed. The ore slurry is fed from the ore trough to the bed surface. Under the action of the horizontal water flow washing and the longitudinal reciprocating asymmetric movement of the bed surface, the direction of movement of the ore particles with different specific gravity and different grain sizes on the bed surface will be different. The slime flows directly along the inclined direction of the bed surface, and the ore particles sinking between the strips are caused by the shaking of the bed surface and the vortex formed by the flushing water in the groove, which occurs according to the difference in specific gravity and particle size. Floor. The ore particles with small specific gravity and large particle size are cleaned to the upper layer by eddy current, followed by the ore particles with small specific gravity and small particle size, and the ceramsite sand is provided in the next layer with large specific and large particle size. The grains drill through the space between the ore grains and are located in the lowest layer. This process is called "segregation stratification".
6S shaking table is usually composed of three parts: bed surface, frame and transmission mechanism. In addition, there are flushing troughs, feeding troughs, machine bases, etc. The entire bed surface is supported or suspended by a rack, and the rack is equipped with a slope adjustment device. 6S shaking table can make the ore particles move in different directions according to their density and particle size, and fan out from the feeding trough along a diagonal line, and discharge along the edge of the bed in order. The ore line is longer and can produce Produce a variety of different quality products. The shaking mechanism is the main component of the shaking table. It is directly related to the looseness, delamination and vertical movement speed of the ore particles on the bed surface. According to the characteristics of generating reciprocating motion, it can be divided into two types. One is the head of the bed that generates approximately symmetrical motion. For example, a spring-supported rapid shaker belongs to this category. It is currently used less and is not described. There are three types of bed features with eccentric toggle, cam lever, and inertia spring.
The advantages of the eccentric connecting shaker head are that the stroke adjustment range is large and the adjustment is convenient. It is better than other bed heads when choosing coarse sand. The shortcomings are the complicated structure of the headboard, the easy to break elbow, and the more easy to wear parts. China's tungsten ore dressing plants often use 6-s shaker heads.
Advantages of 6S shaking table beneficiation: 1. The ore rich ratio is higher than other beneficiation methods. 2. If necessary, multiple products can be obtained at the same time. 3. It does not consume medicine, consumes less power and consumes less water. 4. Concentrate and tailings can be obtained in one selection.
