Руководство по горному оборудованию: What Equipment Should You Use for Gravity Separation of Tungsten, Tin, Niobium and Manganese Ore Sands and Slimes? A Complete Guide to Shaking Tables

The shaker is used to sort ore sands with a particle size of 0.2-2mm and mineral sludge grades such as tungsten, tin, niobium, manganese, chromium, titanium, lead-zinc, gold, and iron (hematite and limonite). It is one of the important devices for gravity beneficiation. This equipment drives the bed surface to perform asymmetrical reciprocating motion through a transmission mechanism, while lateral water flow washes the bed. The material on the bed surface is layered by density and particle size, discharged longitudinally and transversely along the bed surface to achieve sorting. Why choose the shaking bed? Because it has significant advantages such as stable separation, easy control, wide allowable variation of feed concentration, high enrichment ratio, high recovery rate, small footprint, low water consumption, simple structure, no need for power, large processing capacity, easy installation, convenient operation, and low investment with quick results, it is especially suitable for processing fine-grained metal minerals and sludge. Shaking tables are mainly used for gravity beneficiation of metal minerals such as tungsten, tin, niobium, manganese, chromium, titanium, lead-zinc, gold, iron, as well as for sorting ore sand and sludge. They are widely used in concentrators, mining enterprises, rare metal recovery enterprises, and gravity concentrators. People who need shaking beds include concentrators, mining enterprises, rare metal recovery enterprises, gravity concentrators, EPC engineering contractors for beneficiation equipment, equipment distributors and inventors, and overseas mining project buyers. Under what circumstances should a shaking table be selected or replaced? When it is necessary to sort metal minerals such as tungsten, tin, niobium, manganese, etc., with high requirements for enrichment ratio and recovery rate; When old equipment is inefficient, with poor sorting performance or high failure rates; When a new concentrator or gravity processing production line requires high-efficiency re-sorting equipment; When export projects require adaptation to overseas voltage and high-efficiency re-sorting conditions, the shaker should be prioritized. How to choose a shaker? Step one: Confirm the particle size to be selected, ensuring it is within the range of 0.2-0.074mm; Step two: confirm the processing capacity, selecting 0.5-12t/h according to the production line capacity; Step three: Confirm stroke and flush, selecting 10-30mm and 240-360 cycles/min based on material characteristics; Step 4: Confirm bed surface dimensions and lateral tilt angle. Select 152×1825×4500mm and 0-8° based on processing capacity and sorting requirements; Step 5: Confirm motor power: select a 1.1kW motor; Step 6: Confirm the installation foundation, which must be installed on a solid concrete foundation, fixed with anchor bolts, and ensure the feed concentration is within 15%-30%. The cleaning water volume should be between 0.4-0.8 t/h.

Yes. It needs to be installed on a solid concrete foundation, which must support the equipment's weight and operational dynamic load, fixed with anchor bolts.

13. Does the shaking table require power?

Yes, but it only needs a 1.1 kW motor to drive the transmission mechanism, consuming very little electricity, making it an energy-saving gravity separation equipment.

14. What materials are suitable for the shaking table?

It is suitable for gravity separation of metal minerals such as tungsten, tin, niobium, manganese, chromium, titanium, lead-zinc, gold, and iron (hematite and limonite), as well as for the sorting of ore sand and slurry.

16. What is the difference between a shaking table and a spiral chute?

The shaking table requires power and has a relatively small processing capacity, but the separation process is stable, easy to control, suitable for ore sand and slurry, with higher concentration ratio and recovery rate; the spiral chute does not require power, has a large processing capacity, occupies less space, is suitable for fine-grained materials, and has a high concentration ratio.

Standard equipment complies with RoHS and REACH regulations and does not contain SVHC (substances of very high concern). Refer to the product test report for specifics.

19. How to choose the model of a shaking table?

Determine suitability based on the material type and particle size. Choose a model within the 0.5-12 t/h range according to the production line capacity requirements. Select a stroke of 10-30 mm and stroke frequency of 240-360 times/min based on material characteristics.

20. How to use the shaking table in conjunction with a double-ring pulsating high-gradient magnetic separator?

The shaking table can be used for pre-enrichment or rough selection, initially separating heavy minerals from fine-grained materials, and then sending them to a double-ring pulsating high-gradient magnetic separator for further selection, which further improves the concentrate grade and recovery rate, forming a complete gravity separation–magnetic separation combined process. It can also be used in conjunction with a spiral chute to form a gravity separation process with spiral chute roughing and shaking table cleaning.

Technical FAQ

Which test data improves equipment selection?

Provide feed assay, particle-size distribution, slurry density, liberation size and target recovery or concentrate grade.

Can one machine handle every ore?

No. Mineral properties and process conditions change the required separation method, size and configuration.
