Shaker features
The shaker dressing known as out of disk dressing, is the use of mechanical shaking and water flow washing the combined effects of the mineral particles by gravity separation process. Shaker re-election of the plant equipment, its salient characteristics of high-grade ore is high, vertical sand mill and used it for the final concentrate, while the separation of the final tailings, can effectively deal with the fine-grained material. Election divided the upper limit of particle size of 3 mm, the lower limit if the election of cassiterite and wolframite to 0.4 mm, gold shaking table 1 mm below the materials are usually used to choose points. More complex structure of the shaker, the operation is not easy, low productivity, the area occupied by plant. These shortcomings in the research work in progress.
Depending on the selected points of ore particle size, can be divided into coarse sand shaker ore than 0.5 mm and the fine sand shaker handle 0.5-0.074 mm and 0.074-0.037 mm ore mineral mud shaker, a total of into three. Their main differences is that different forms of re-bar to the bed.
shaker of the dressing process
Rinse water to the horizontal direction A from the surface of the bed to the bed surface to form a uniform thin layer of water on the bed surface, and from A to B the direction of flow along the bed surface. Pulp from A to the side of the bed surface due to the reciprocating motion of the role of water and bed surface, mobile sand washing plant the mineral particles are also different due to different particle size and the proportion of the movement direction of the bed surface. The finest of the fine mud shed directly along the tilt direction of the bed, submerged in mineral particles in the bed complex Article stratification occurred, according to the different specific gravity and particle size, coarse and light mineral particles produced by vortex cleaning the top, followed by the thin and light mineral particles, then a layer of heavy and coarse mineral particles, smaller than the major particle size mineral particles drilled gap between the mineral particles sink to the lowest level. To complex height from the drive end side to the concentrate (ie, from C to D) is decreased, when the mineral particles move to the D-side along the trench, with the upper flow rate of the larger lower flow rate is slower horizontal water, first located in the upper small proportion of mineral particles to the B-side along the tilt direction gradually washed away. Large proportion of mineral particles remain in the groove of the reciprocating differential shaking the bed along the CD direction, the proportion of mineral particles in the grooves along the CD direction to move to the concentrate side. So that the different proportion of different particle size of mineral particles on the bed surface due to the different characteristics of the direction of movement, and ultimately to form fan-shaped distribution. Which can be a variety of products to complete the election other purpose.
Factors affecting the shaker dressing
The main factors affecting the shaker beneficiation ore properties and operating conditions.
The nature of ore refers to the proportion of mineral particles, particle size and shape. In order to reduce the impact of mineral capsules degrees of separation material into the shaker should be the advanced nature of hydraulic classification, a small proportion is coarse-grained than the major fine.
Operating conditions, including the inclination of the bed, wash water, stroke, and washed.
The inclination of the bed affect the rate of water flow. Other fine materials should be selected to reduce the speed of the water, it should be smaller inclination. Big dip in the sorting of coarse-grained materials. The inclination of the adjustment range between 0-10 ¡ã. 3.5-4 ¡ã, choose Do not coarse sorting of fine when 2-2.5 ¡ã, 2 ¡ã about the sorting slime.
