1.Application Fields of gold trommel screen:

Gravity gold processing is the most traditional method of extracting gold in alluvial and rock gold mine used widely. It is more as a secondary process to recover coarse gold in the gold sluice box and the fine gold go the gold centrifugal concentrator and shaking table for concentrating.
1. Washing and Screening: Use gold trommel to wash and screen the raw material into 0-2mm, 2mm+ particles.
2. Jig machine: Use jig machine to separate the 2mm+ gold.
3. Gravity concentration: Use gold  shaking table to separate the gold concentrate from the powder(0-2mm).


2.Introduction of gold processing machine:

Gold Trommel Screen
Trommel screen, also known as a rotary screen, is a mechanical screening machine used to separate materials in the mineral and solid-waste processing industries. Trommel screen is mainly used in gold processing, metallurgy, mine, coal, power station, water conservancy project, building industry, light industry, and chemical industry. It is efficient screening machine for the classification of bulk material such as coal, minerals, coke etc.

Jig Machine
Jig machine separators are devices used mainly in the mining industry for mineral processing, to separate particles within the ore body, based on their specific gravity. It is widely used to separator tungsten, tin, gold, red iron, brown iron, manganese, titanium, antimony, lead, tantalum, niobium and other minerals.
There are many applications where the jig separator 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.

Gold Shaking Table
Gold haking table is one of the main equipment of gravity concentration, which is suitable for rough separation and concentration. It is widely used in separating gold, tungsten, tin, tantalum, niobium and other rare metals and precious metal ore. Can be used for roughing, concentration, scavenging different operations, separating coarse sand (2-0.5mm), fine sand (0.5-0.074mm), slime (-0.074mm) of different grain grade.

3.Main Characteristics:

1. The angle of inclination of installation is small and the machine is not very easy to be blocked.

2. Multiple screen size and easily changed screen plates.

3. Low noise and little powder dust pollution

4. Convenient installation and stable operation

5. High screening efficiency and large processing capacity


4.Working Principle:

Materials fed into the trommel screen, is lifted up by the rotation and aerated as it falls back down. This action is repeated with each revolution along the length of the drum. The three coupling shafts are designed higher than the screening surface, which enables the larger particles being stirred up and thus increases the screening efficiency. The particles larger than screen mesh size are discharged as the upper size materials which could be delivered away by belt conveyor, while the particles smaller than screen mesh are discharged as under size materials.
