Beneficiation shaking table is a gravity separation equipment for separating fine-grained ores. It is widely used for the separation of tungsten, tin, tantalum, niobium and other rare metal and rare metal ores, as well as iron manganese ores. In recent years, it has also been reported that shaking table is used to recover iron minerals in tailings of magnetic separation plants and non-metallic minerals such as mica. Analysis on the advantages of shaker beneficiation shaker is used as gravity separation equipment. It has been widely used for the separation of placer gold and other minerals, mainly for gold or coal preparation. Classification of beneficiation Shakers: sand beneficiation shaker, slime beneficiation shaker, FRP beneficiation shaker, 6-s beneficiation shaker, LS beneficiation shaker, etc.
The vibrating screen gold digger of gold placer equipment has clear actual operation, simple actual operation, reliable work and high express sorting efficiency. For rough sweeping, the utilization rate of actual operation can be about 80%; When effective minerals and gangue are fully dissociated, concentrate and tailings pond can be obtained at one time. What kind of raw ore can be selected by Shajin vibrating screen machinery and equipment? The Shajin vibrating screen can make the iron ore particles move in different directions according to their different relative density and particle size distribution, and form a fan shape along the straight line at the beginning of the iron ore safety channel, and then discharge successively along the edge of the bed surface; And its blanking pipe is very long. It can accurately produce and manufacture all kinds of commodities with different quality, such as concentrate, secondary concentrate, medium concentrate and tailings pond.
Sand gold equipment is generally composed of Bayi parts: bedroom bed, motor, grader, bed surface, iron ore pool, stainless steel sink, strip steel and air inlet system. It is worth mentioning that the cleaning tank, mining tank and base are also supported by the frame structure or suspended on all bed surfaces, and the sound card frame is equipped with skew adjustment equipment.
The longitudinal repeated work on the bed surface is organized and maintained according to the guide rod crankshaft transmission system. According to the drive belt driver, the motor controls the large belt pulley to rotate the engine crankshaft, and the crank arm moves left and right. When the rocker moves down, the support frame pushes the rear axle and the reciprocating rod backward, and the elastic yellow is reduced. The bed surface is connected with the reciprocating rod according to the crankshaft seat to promote the bed surface to move backward. When the rocker moves upward, the bed surface moves forward because of the support force of the yellow spring.
When the bed surface moves forward for a period of time, the viewing angle in the middle of the support frame changes from large to small, and the horizontal moving rate at the end of the support frame changes from small to large. Therefore, the forward work movement of the bed surface is slow and rapid. Conversely, when the bed surface reverses, the work will be transported quickly and slowly, resulting in differential, which can ensure the forward work of raw materials on the bed surface, and carry out the sorter according to the proportion.
The bed looks like a ladder at the top corner. In the wooden frame structure, the wood board is unfolded along the skew direction (45 degrees to the axis). The bed surface is divided into two types: paint tank bed surface and vulcanized rubber bed surface. The surface of gray paint slotted bed is used to select fine mud, and the surface of vulcanized rubber bed is used to select coarse iron ore. The surface of the vibrator for selecting fine mud has an inclination of about 0.5 degrees in the longitudinal direction, while the vibrator for sorting coarse sand has an inclination of 1-2 degrees in the longitudinal direction and rises at the concentrate end. The size of the longitudinal slope is adjusted by the anchor bolts on the support point organization.
The bed surface is supported on the swing tissue by the swing tissue. Swing the support point to make the bed surface move back and forth in the arc shape of the vertical plan. Place the circular steel of the swing support point on the adjustment seat plate, and when the handle rotates the adjustment seat plate on the saddle according to the adjustment screw, the skew angle of the bed can be adjusted.
Beneficiation shaker smelter is one of the key gravity separation methods of placer gold equipment. At this stage, the common is the flat slot vibrating screen.
