A shaking table is a gravity concentration device for fine materials that separates minerals by density and particle size using a vibrating tabletop and flowing water. It is commonly used to concentrate gold and other heavy minerals like tin, tungsten, silver, lead, and zinc.
It is suitable for fine-grained metallic minerals and coal, including gold, tin, tungsten, silver, lead, zinc, tantalum, niobium, iron, manganese, ferrotitanium and similar heavy minerals.
The machine can classify granularity from about 2 mm down to 0.02 mm (ore and slime). Typical feed-size specifications list up to 2–0.074 mm depending on material and plant setup.
Model: L-S (6-S). Key specs include water quantity 0.4–0.8 t/h, stroke 10–30 mm, stroke frequency 240–360 cycles/min, motor 1.1 kW, treating capacity 0.5–1.2 t/h, minimum pulp density 15–30%, table size 1520×1825×4500 mm, overall dimension 5454×1825×1242 mm, and weight about 1012 kg.
Rated treating capacity for the listed model is about 0.5–1.2 t/h. The unit is designed for high processing capacity, high recovery rate and a high enrichment ratio, though actual recovery depends on ore characteristics and plant conditions.
Water is used to form the pulp stream and to help stratify particles on the table. Recommended water quantity for the model is 0.4–0.8 t/h; exact flow should be adjusted based on feed consistency and desired separation.
Provide a level, rigid foundation able to support the machine weight and vibration. Ensure access to suitable power (motor 1.1 kW), a controllable water supply, and a discharge area for concentrates and tailings. Allow clearance for maintenance around the unit.
Adjust key parameters including table slope (horizontal tilt 0–8°), stroke amplitude (10–30 mm), stroke frequency (240–360 cpm), water flow (0.4–0.8 t/h) and feed rate. Fine-tune riffles and feed distribution to optimize stratification and concentrate grade.
Regularly clean the table surface and riffles, inspect and tighten fasteners, lubricate bearings per manufacturer intervals, check motor and drive components, monitor wear parts and replace rubber or riffles as needed, and verify water lines are clear.
Always isolate power before maintenance, wear appropriate PPE (gloves, eye protection, hearing protection as needed), keep hands and tools away from moving parts, maintain clean, dry working areas to prevent slips, and follow lockout/tagout procedures.
Pulp density (minimum 15–30% solids by weight as a guideline) and particle density differences are critical for effective separation. Too dilute or too dense pulp, or insufficient density contrast between minerals, will reduce separation efficiency.
Yes. The shaking table is designed for fine materials and can treat both coarse fines and slime fractions within the stated feed-size range (down to 0.02 mm), though performance depends on correct parameter settings and feed preparation.
The manufacturer supplies a range of table concentrators and should provide spare parts such as motors, drive components, riffles, rubber beds and wear parts. Contact the supplier for availability and lead times.
Advantages include simple gravity-based separation (no chemicals), suitability for fine particles, relatively low power consumption (motor 1.1 kW), high enrichment ratio and recovery when properly operated, and adaptability to a variety of heavy minerals.
Properly classify and deslime feed to the recommended size range, ensure consistent feed rate and pulp density, remove oversized tramp material, and distribute feed evenly across the table to promote uniform stratification and efficient separation.
