shaking table in ore processing | fote machinery

Applied material: tin, tungsten, gold, silver, lead, zinc, tantalum, niobium, titanium, manganese, iron ore, coal, etc. Advantages: high concentration ratio of dressing, convenient adjustment and easy to get obvious separation.

The shaking table beneficiation can not only be used as an independent beneficiation method, but also is often combined with methods such as jigging, flotation, magnetic separation by centrifugal concentrator, spiral classifier, spiral chute and other beneficiation equipment.

The shaking table is mainly used for the separation of copper, tungsten, tin, tantalum, niobium, chromium, gold and other rare metal and precious metal ores. In addition, it is widely used in the separation of iron, manganese ore and coal. Before flotation, it was also used in the dressing of nonferrous ores.

It can be used for different operations such as roughing, concentration, sweeping, etc., to separate coarse sand (2-0.5 mm), fine sand (0.5-0.074 mm), sludge (-0.074 mm) and sand with other different particle sizes. It is very effective equipment for selecting fine-grained materials below 1 mm, especially below 0.1 mm.

The bed surface can be made of wood, FRP (glass fiber reinforced plastic), metals (such as aluminum, cast iron) and other materials. Common shapes of the bed surface are rectangle, trapezoid and diamond.

There is a feeding chute on the upper right of the bed surface, the length of which is about 1/3~1/4 of the total length. There are many small holes on one side of the feeding chute, so that the slurry can be evenly distributed on the bed surface.

Connected to the feeding chute is the flushing tank, which accounts for 2/3~3/4 of the total length of the bed surface. Many small holes are made on the side of the tank so that the flushing water can be evenly fed along the longitudinal direction of the bed.

The light mineral particles in the upper layer are subject to great impact force, and most of them move downwardly along the bed surface to become tailings. Accordingly, this side of the bed surface is called the tailings side.

The heavy mineral particles at the bottom of the bed move longitudinally by differential movement of the bed surface, and are discharged from the opposite of the transmission end to become concentrate. The corresponding position of the bed surface is called the concentrate end.

The horizontal and longitudinal effects of mineral particles of different densities and particle sizes on the bed surface are different. The materials finally spread out in a fan shape on the bed surface, and a variety of products of different quality can be obtained.

The amount of feeding ore is related to the granularity of the feed. If the ore grains are relatively coarse, the required amount of feeding ore is large. However, if it is too large, it will cause zoning problems. In this case, it is necessary to move the concentrate intercepting plate to increase the flushing water and the horizontal slope of shaking table surface.

The Cr2O3 content in a certain lean chromite ore in Zimbabwe is only 8.19%. Fote has conducted research on the beneficiation technology and equipment of the lean chromite ore, finally decided to adopt the beneficiation method: tail discharging by the strong magnetic separationfull-grain separation by shaking table. The indicators are relatively good.

Step 2 Then use Fote magnetic separator for strong magnetic separation to remove qualified tailings with a yield of 50.21%, and the tailing grade is only 2.19%. As a result, the amount of ore entering the shaking table is reduced by half, and the number of shaking tables is greatly reduced. At the same time, after throwing the tail, it creates favorable conditions for the sorting of the shaking table and further improves the sorting index.

The shaking table is a gravity beneficiation equipment for selecting fine materials, such as the tin, tungsten, gold and silver, lead, zinc, antimony, bismuth, iron, manganese, ferrotitanium and coal, etc.

The shaking table is a gravity beneficiation equipment for selecting fine materials. When the gold shaking table in action, the effective particle size range of metal ore is 3~O. 019 mm. While it processes the coal, the upper limit granularity is 10mm. The outstanding advantage of the shaker is that the sorting precision is high, and high-grade concentrate or waste tailings can be obtained by one sorting, and multiple products can be taken out at the same time. Besides, the shaking table is easy to adjust.

Mining gold shaking table is a common mineral processing equipment for sorting fine ore. When the metal ore is processed, the effective particle size range is 3~O. 019 mm, the upper limit particle size can be up to 10 mm when coal is selected. The outstanding advantage of 6-S shaker is the high precision of sorting. High-grade concentrate or waste tailings can be obtained by one selection, and multiple products can be taken at the same time. The flat 6-S shaker is easy to handle and easy to adjust. The main disadvantage is that the equipment covers a large area and the processing capacity per unit of the factory area is low.

Shaking table is widely used in many industries, and can be used for rough selection and sweeping of materials. Its main materials are various metals and heavy metal materials such as gold, silver, zinc, tungsten, iron, manganese, lead, coal, etc. The size of coarse sand is 2-0.5mm, and the fine sand is 0.5-0.074mm. The effective recycling range of shaking table is 2-0.22mm when processing the tungsten, tin and other metal ore materials.

The gold shaking table is made up of table surface, main frame, transmission device and motor. Moreover, the gold shaking table will be armed with the water filling chute, feeding chute and engine base.

The motor of the shaking table drives the crankshaft to rotate the rocker through the belt and then moves up and down. When the rocker moves downward, the mineral material enters through the mining channel on the inclined surface. Shaker sink provides lateral impact water.

The material with different specific gravity, particle size, and density flushed with rinsing and will be selected and output from the concentrate mouth of shaking table, and the tailings mouth. Thus, the processed ore is the high-quality concentrate. However, because of the replacement of mining gold shaking table, FTM Machinery, as the gold shaking table supplier, had improved a lot in term of its throughput and accuracy.

4.After checking the installation connections, the empty shaking table runs for 1-2 hours to check whether the bed surface is running smoothly, whether the connection is loose, shaking or sliding, whether the lubrication is good, and 2whether the lateral slope adjustment is flexible and stable.

6.If there is no problem with empty shaking table, you can put the ore there. according to the ore transportation and zoning on the shanking table surface, adjusting the ore concentration and concentration, stroke, cross slope and flushing water volume, etc.

shaking table experiments to evaluate the boundary effects on seismic response of saturated and dry sands in level ground condition | springerlink

The laminar shear boxes (LSBs) are commonly preferred for geotechnical physical modeling over the fixed wall boxes; the latter may suffer from problems associated with wave reflection. This paper mainly describes the seismic response of a uniform layer of loose saturated and dry sands in rigid and flexible boundary conditions. A lightweight LSB was recently designed and fabricated by the authors for physical modeling of geotechnical earthquake engineering problems. To investigate the boundary effect on the seismic response of level ground, a series of shaking table tests were conducted with both LSB and rigid wall containers in identical conditions. The seismic performance of the free-field ground in the experiments is evaluated in terms of time histories, shear stressstrain hysteresis loop, and dynamic soil properties. The dynamic movements of all layers in the LSB, captured by image processing techniques, are compared with that of the rigid end-wall condition. The results demonstrate that acceleration and settlement of the ground surface are highly affected by artificial boundaries in both dry and saturated sands. It is shown that the hysteresis loops estimated from the LSB tests are more compatible with the cyclic behavior of sands, compared with those of the rigid box tests.
