China Suppliers Factory Shaking Table - High-Efficiency Gravity Separation Machine for Beneficiation of Precious Metals
Working principle
Beneficiation of shaking table is a process that the mineral particles are loosened, layered, and banded on the inclined bed surface by the combined action of mechanical asymmetric reciprocating motion and thin-layer inclined water flow. The minerals can be sorted according to density.
First, add materials into the ore chute. The table surface is inclined, and many parallel riveting bars or grooves is nailed on the table surface along the longitudinal direction. There is a transmission mechanism installed at the end of the shaking table, which drives the bed surface to shake asymmetrically in the longitudinal direction. The bed surface is tilted toward the tailings side at a horizontal angle of 1.5 to 5 degrees. Then the slurry and flushing water are fed from the side with a higher slope of the bed surface. By impact of the fluid and the differential reciprocating force of the transmission device on the shaking table, the mineral particles are layered according to density and particle size and move along the bed surface in different directions, showing regular fan-shaped banding. At last they are discharged from different areas with separating into concentrate, middlings, and tailings by separate collection.

Frequently Asked Questions
How does the shaking table separate minerals?
It separates mineral particles according to density. The process is driven by the combined action of mechanical asymmetric reciprocating motion and thin-layer inclined water flow on an inclined bed surface, which loosens, layers, and bands the minerals.
What is the tilt angle of the shaking table surface?
The bed surface of the shaking table is tilted toward the tailings side at a horizontal angle ranging from 1.5 to 5 degrees.
What is the motor power and table weight of the 6-S model?
The 6-S model is equipped with a 1.1 kw motor, and the surface weight of the table is 1012 kg.
What is the processing capacity for coarse sand vs ore mud?
The capacity for coarse sand ranges from 1.0 to 1.8 t/h (with a feed size of 2.0-2.5 mm), whereas the capacity for ore mud is lower, ranging from 0.3 to 0.5 t/h (with a feed size of -0.074 mm).
How much flushing water is required during operation?
The required flushing water volume depends on the material type: 0.7-1.0 t/h for both coarse and fine sand, and 0.4-0.7 t/h for ore mud.
