6S large channel steel beneficiation shaking table gravity sorting equipment with large processing capacity and high recovery rate

Description :

  The 6S large channel steel beneficiation shaker is a mining machinery based on the principle of gravity separation, mainly used for the sorting operation of fine-grained materials. This device uses the reciprocating asymmetric motion of the bed surface and the flushing effect of water flow to separate and stratify mineral particles of different densities on the bed surface, thereby obtaining concentrate, intermediate ore, and tailings. It is particularly suitable for the selection of rare and precious metal ores such as tungsten, tin, tantalum, niobium, and gold, and can also be used for the coarse and fine selection of black metal ores such as iron ore and manganese ore. The 6S large channel steel beneficiation shaker solves the problems of low sorting accuracy and unstable recovery rate in traditional chutes, and is a key equipment for mining enterprises to improve resource utilization. Typical operating conditions include grading and sweeping operations after grinding the raw ore.

  The 6S large channel steel ore dressing shaker adopts high-quality channel steel as the head support structure. Compared with ordinary angle steel or wooden structures, it has higher rigidity and stability, and can withstand long-term high-frequency vibration without deformation. The bed surface is usually made of fiberglass or wooden materials, with grooves or triangular grooves engraved on the surface to enhance the layering effect of mineral particles. According to the industry standard JB/T9028-2015 "Mineral Processing Shaker Bed", the common size of the bed surface is 4500mm × 1850mm or larger, and the stroke range is usually adjustable between 15-30mm, with a stroke rate of 280-320 times/minute. The overall equipment has undergone anti-corrosion and rust prevention treatment to adapt to the humid and dusty mining environment, ensuring stable mechanical performance under continuous operation and meeting the requirements of mining safety and environmental protection.

  When selecting, it is necessary to choose the appropriate 6S large channel steel beneficiation shaker model based on the ore properties, processing capacity, and feed particle size. For materials with large processing capacity and coarse particle size, a large channel steel structure should be selected, which has strong bearing capacity and good impact resistance; If pursuing high selection accuracy, attention should be paid to the geometric shape and material wear resistance of the bed surface slats. This equipment is not suitable for the treatment of mineral mud with severe mud formation or extremely fine particle size (less than 0.037mm) and not fully decomposed. In such cases, it is recommended to use spiral chutes or flotation processes. Compared with spiral chutes, the 6S large channel steel beneficiation shaker has a higher sorting ratio, but the processing capacity of a single machine is relatively small. It needs to be reasonably configured according to the site and production capacity requirements to avoid overloading of large or small machines.

  When installing the 6S large channel steel ore dressing shaker, it is necessary to ensure that the foundation is flat and firm, and the centerline of the bed head is perpendicular to the longitudinal centerline of the bed surface, with a deviation not exceeding the specified range, to ensure the accuracy of the movement trajectory. In daily maintenance, it is necessary to regularly check the elasticity of the spring at the head of the bed and the wear of the connecting rod, and add lubricating oil in a timely manner to reduce friction loss. Common faults include deviation of the bed surface and severe wear of the conveyor belt, leading to a decrease in sorting efficiency. In this case, it is necessary to adjust the length of the pull rod or replace the bed surface lining. Before stopping the machine, the ore feeding should be stopped first, and the machine should be stopped only after the bed material is washed clean to prevent the sedimentation of mineral sand from blocking the groove, extend the service life of the equipment, and maintain stable sorting indicators.
