High efficiency concentrator is suitable to dewater concentrate and tailings in concentrator plant. The high efficiency concentrator produced by our company is a machine for removing the water in the ore concentrate and the tailings in the ore beneficiation plant.
Thickener (also known as thickener or agitator) is suitable for concentrate and tailings dehydration treatment during the beneficiation process to increase the slurry concentration from 20-30% to 40-70%. It is of great significance to improve the utilization rate of backwater, the concentration of bottom flow and protect the environment. In fact, the high efficiency concentrator is not a kind of simple sedimentation equipment, but a new type of dehydration equipment combined with the characteristics of mud layer filtration. It is divided into central transmission type, peripheral transmission type, sludge, intermittent type, vertical flow and continuous thickener.
High efficiency concentrator is suitable for dehydration, concentration and treatment of tailings in concentrator factory, and widely used in metallurgy, chemical industry, coal, non-metallic mineral processing, environmental protection and other industries.
The high efficiency concentrator generally consists of the thickener pool, transmission device, lifting device, feeding device, unloading device and signal safety device. The main feature of this machine is to add a certain amount of flocculant to the pulp to be concentrated, so that the ore particles in the pulp will form flocculation groups and accelerate its settlement rate, so as to improve the concentration efficiency.
Increasing the size of solid particles in slurry and the settlement area of high-efficiency concentrator can improve the processing capacity of high-efficiency concentrator. The particle size of settling particles can be increased by adding flocculant to high-efficiency concentrator to make fine particles agglomerate. The inclined plate in the high-efficiency concentrator can increase the settlement area, shorten the settlement distance of particles and improve the concentration efficiency. The test and industrial production shows that under the same processing capacity, the diameter of the high-efficiency thickener is only two-thirds to half of the diameter of the ordinary thickener, and the area is about one-ninth to one-fourth of the ordinary thickener, while the processing capacity per unit area can be increased several times to dozens of times.

Answer: Key factors influencing separation include the table’s motion (stroke and frequency), water volume and slope, feed rate and concentration, and the feed material’s particle size and shape. Proper adjustment of these factors is critical for efficient separation. The table’s longitudinal and transverse slopes must be precisely controlled. The feed concentration should also be appropriate, typically 20-30% for coarse minerals and 15-25% for fine minerals.
Answer: Operation involves observing the bed surface and adjusting the slope, water flow, and feed rate. Regular maintenance includes checking for loose parts, lubricating moving components, inspecting for wear, and cleaning the table surface. Preventative maintenance should be performed regularly, with intervals ranging from every month to once a year.
Answer: Common issues can include table shaking or choppy cuts, uneven material distribution, or poor separation. Troubleshooting may involve checking for loose bolts, damaged springs, or misalignment, adjusting belt tension, inspecting electrical components, and ensuring proper lubrication. If there’s unusual noise, identify the source and eliminate the problem.
Answer:
Advantages: Shaking tables offer high enrichment ratios, are relatively simple to operate, and produce visible separation zones, allowing for easy adjustment and monitoring. They are suitable for a wide range of particle sizes and densities.
Disadvantages: They typically have lower throughput capacity compared to some other methods like jigs or spirals. They also require a relatively large footprint and consume a significant amount of water.
Answer: The selection depends on the material being processed, the desired throughput, and the particle size range. Factors to consider include the deck area, stroke length, and riffle design. Consulting with a manufacturer or expert is recommended to determine the optimal configuration.
