Cross section appearance and specifications of the incoming and outgoing strips of the shaking table

The shaking table is one of the main equipment used by mining companies for re selection. The raw materials used for the back and forth bars of the shaking table should be wear-resistant and corrosion-resistant. The structural design is that the cross-sectional shape and specifications of the back and forth bars of the shaking table endanger the height of the horizontal flow of water and vortices on the bed surface, thereby endangering the loose stratification of mineral particles and the selection of high relative density minerals. The cross section of the coarse sand bed should be selected that can stimulate strong vortices, such as a rectangular box cross section, and the aspect ratio of the cross section should be large. The cross section of the mineral mud bed should be light and gentle, and the aspect ratio or deep layer (such as grooves) should be small to facilitate stable passage of mineral flow, weaken the compressive strength of vortices, and prevent damage to small and heavy minerals. The length of the strip is gradually extended from the feeding side to the discharging side, so that the entire process of ore flow discharged from the feeding side of the bed surface gradually improves the scanning process, which is beneficial for improving utilization efficiency. The total width of the coarse sand and fine sand bed is generally the same from the transmission system end to the titanium concentrate end. The triangular strip or groove of the mineral mud wound gradually decreases from the transmission system end to the titanium concentrate end and dies out in the mine. The aspect ratio of the incoming strip gradually decreases from the end of the transmission system to the end of the titanium concentrate, the groove gradually becomes thinner, and then the concentrate mountain disappears. During the entire process of moving the raw materials from the transmission system end to the end of the titanium concentrate, light particles can be continuously eliminated by horizontal water flow,. From the feeding side to the discharging side, the height to width ratio of the incoming and outgoing strips gradually increases, or there is an increase of 1 strip or some two colors for each incoming and outgoing strip, but there are also many unchanged incoming and outgoing strips. The layout method of the strip on the bed surface is generally parallel to the direction of the transmission system and parallel to the plane layout. There is also a method of arranging the 1st or 2nd section strip into a slope in the middle. This type of layout method is also known as wave shaped strip layout. This type of strip is very easy to discharge light minerals, which can increase the output of the shaking table. Moreover, the increase in spacing between ore particles during the operation of the strip is beneficial for improving utilization efficiency. However, the production and processing of this type of strip is more inconvenient, and the excuses for skewed and parallel segments are not easy to match. Therefore, in production and manufacturing, the layout of multiple strips with parallel planes and lines is still commonly used. The level of familiarity and sparsity of the layout of Laifu strips on the bed surface has an impact on the screening index value of the shaking table. Dense incoming and outgoing strips increase the maintenance opportunities for heavy mineral materials and improve the utilization rate of titanium concentrate. However, the incoming and outgoing strips should not be arranged too densely, otherwise the resource yield of the concentrate will be too high, which will harm the grade of titanium concentrate. The middle of the incoming and outgoing strips is generally arranged with equal spacing, and some bed surface incoming and outgoing strips are arranged in a friendly and sparse manner. From the feeding side to the mining side, the incoming and outgoing strips change from dense to sparse, which is more effective. From the transmission system end to the concentrate hill, the multiple strips of slowly pinch out. The connecting line of each pinch out point of the multiple strips is the pinch out line, and the intersection angle between the pinch out line and the ore discharge side is called the pinch out angle. The size of the pinching angle has an impact on the output of the shaking table and other performance indicators; If the pinching angle is reduced, the precision mining will be extended, which can strengthen the entire process of clean separation and be beneficial for improving the grade of titanium concentrate; However, after the reduction of the pinch out angle, the feeding trough decreases, and under the same output standard, the ore flow becomes concentrated, leading to an increase in the grade and loss rate of the tailings pond. If the pinch out angle is too large, it is not conducive to improving the grade of titanium concentrate.
