Application of  River placer gold mining equipments

Concentrating Tables are designed to wet gravity-based separation of minerals and other granular materials.

There are many applications where the concentrating table is of particular value and cannot be equaled for economical and efficient performance. They are effective in processing precious and base metal, rare metal and non-metallic minerals.

 

Construction

Head Motion  The head motion is of r ed construction and requires minimum maintenance. Its internal mechanism is splash lubricated from an integral oil sump.

Decks   The decks are built of 16 mm zircon-reinforced fiberglass with fabricated steel frames at the bottom and are easy to clean, requiring little maintenance. The specific gravity of fiberglass made into decks is one third of that of steel, while its strength reaches as high as 70% that of steel. This fiberglass desks also has the characteristic of water-resistance and corrosion-resistance and can hold the shape unchangeable at ±50°C.

Feed and Water Box A wooden feed distributing box with hopper and a long water box are attached to the iron of the deck, giving a very even distribution of feed and water.

Base   A choice of ordinary type, groove steel support or big channel steel support is available.

 

Technical Specification

Shaking Tables have three distinct deck designs available.

The course ore deck is designed for recovering particles sized from 0.5 mm to 2 mm; the fine sand deck is designed for recovering fine particles in the range of 0.074 mm to 0.5 mm; the slime deck is designed for recovering super extremely fine particles in the range of 0.05 mm to 0.074 mm.
