Shaking Table for Mineral Processing

Shaking tables are widely used in mineral processing of tungsten, tin, tantalum niobium, gold and other rare metals and precious metal ores. They can also be used for the separation of iron, manganese ore and coal.

Shaking table working principle

The density of raw material is 20%-25% in the feed tank, and it flows to the shaking table surface. The ore particles are loosened and stratified in the bed groove by water washing and shaking table surface vibration.
Because of the different density and particle size, the direction of movement is also different, so the ore particle group from the feeding trough along the diagonal thread fan out, the product along the edge of the bed, the ore discharge line is very long. Therefore, the shaking table can accurately produce a variety of products of different quality.

The separation principle for the shaking table , the minerals groups will be loosed separated selectively carried on the table surface by the different densities, differential motion supplied by head motion, the force of the inclined stream and various riffing. There fore, there is a clearly sector branch on the table and various products will be collected by different compositions and grades of the minerals. They could be used for the roughing or cleaning work in the ore dressing plant. The size of the minerals is 2-0.074mm and it is for -0.074mm also. It is fit for the minerals of W、Sn、Ta、Nb、Fe、Mn、Ti、Cr、Au，Sea sand, pymite, coal and other minerals with enough difference density.

Function Features

The high separation accuracy of the shaking table is its outstanding advantage. The final concentrate, final tailings and intermediate products can be obtained by single separation of raw ore. The concentration ratio is very high, especially for tungsten, tin, placer gold, tantalum niobium ore.
1, high recovery rate, high enrichment ratio;
2, easy to install, simple operation;
3, a variety of different shaking table surface to choose from, when we choose shaking table for gold, the 88 or 120 grooves bed surface is recommended.

Construction and Mechanical Features

ZJH minerals shaking tables are euqipped with a totally enclosed self-lubricating head motion.  It includes an lubricationg oil reservoir for perfect splash lubrication. This will protects the moving parts,reducing operating and maintenance costs to minimum degree.

The shaking table surface are covered by 16mm fiberglass and emery. The features of this design are heavy duty, wear resistant, corrosion resistant. It make the shaking table for long life service time and allows the shaking table working well for different minerals concentration and on different weather conditions

Technical Specification

Coarse Shaking Table is suitable for processing of coarse particles 0.5—2 mm. Fine Shaking Table is suitable for processing of fine particles 0.074—0.5 mm. Slime Shaking Table is suitable for processing of Slime particles ≤0.074 mm.

Typical Application

a. Shaking table for placer gold mining

Shaking table is always matched with jig machine for placer gold mining. The flow chart of placer gold mining as below.

Shaker table is working for placer gold extraction. It is working in high efficiency. It shows the placer gold concentration in a bowl at the discharding end of the shaker table.

b. Shaking tale for extraction of gold from its ore

c. Shaking table for tin ore processing

the density of tin ore is higher than that of symbiosis minerals, shaking table is generally adopted for tin ore processing plant.

d.  Shaking Table for recovery of Monazite, Rutile, Zircon from beach sand

we could do custom-tailored shaking table according to client’s requirements, like multi-layer (2 or 4 layer ) shaking table .
