Guinea gold mine project (drum tromme screen + vibrating sluice box +carpet sluice box + shaking table) In the vast and fertile land of Guinea, the gold mine project is in full swing. In order to ensure efficient and environmentally friendly mining of gold, the project uses a series of advanced mineral processing equipment such as drum screen, agitation chute, flat chute and shaking table. The following is a detailed introduction to these equipment and their application in the Guinea gold mine project.
One. Drum trommel screen
1. Working principle The working principle of the drum screen is relatively simple and efficient. Its core component is an inclined drum with sieve holes of different sizes and shapes on the surface of the drum. When the drum rotates driven by the drive device, the material enters from one end of the drum. With the rotation and tilt angle of the drum, the material continues to roll, throw and fall in the drum. In this process, material particles smaller than the sieve hole size will leak out through the sieve hole, while materials larger than the sieve hole size will continue to roll along the drum and eventually be discharged from the other end of the drum.
2. Application Advantages Efficient screening: By adjusting the speed, inclination angle and screen size of the drum, the screening and separation of materials of different particle sizes and types can be achieved. Environmental protection and energy saving: The drum screen will not produce dust pollution during the screening process, and the energy consumption is relatively low.
Two. vibrating sluice box
1. Working principle The agitation chute is a kind of placer gold ore sorting equipment developed on the basis of the ordinary fixed chute. When the slurry enters the chute, under the action of the water flow, the light minerals and some fine-grained heavy minerals flow rapidly through the chute surface with the water flow. At the same time, the rubber plate at the bottom of the chute is agitated up and down under the action of the agitation mechanism, producing an effect similar to jigging. This agitation causes the heavy minerals to be continuously loosened, layered and settled between the bars of the chute, and finally forms a heavy mineral layer. Due to its large specific gravity, the gold in the heavy minerals is gradually deposited between the bars at the bottom of the chute under this action, realizing separation from the light minerals and some fine-grained heavy minerals. 2. Application Advantages Efficient sorting: The agitation chute can efficiently separate gold particles and improve the recovery rate. Strong adaptability: suitable for the selection of placer gold ores of different particle sizes and types.
Three.carpet sluice box
1. Working principle The flat plate chute is mainly separated by the sliding speed and direction of the material on the flat plate. The material is fed from one end of the chute and slides down the chute under the action of gravity and water flow. Due to the different sliding speeds and directions of different materials, materials of different particle sizes and types can be collected at different positions of the chute. 2. Application characteristics Simple structure: The flat plate chute structure is relatively simple and easy to maintain. Convenient operation: The operator can control the separation effect by adjusting the feed amount and water flow rate.
4. Shaking table
1. Working principle The motor of the shaking table drives the pulley to drive the crankshaft of the shaking table equipment to rotate the rocker and move up and down. When the rocker moves downward, the mineral material on the inclined table with a rifling bar comes in through the ore trough, and the shaking table water tank provides lateral impact water. In this way, while vibrating and flushing, minerals with different specific gravities, particle sizes and densities flow out from the concentrate port and tailing port of the shaking table in different directions to directly form concentrates.
2. Application Advantages High ore-rich ratio: The ore-rich ratio of the shaking table is usually much higher than that of other beneficiation methods. High precision: The shaking table can accurately separate minerals of different particle sizes and densities, improving product quality. Environmental protection and energy saving: The shaking table does not consume reagents during the beneficiation process and consumes less electricity.
5. Application in the Guinea gold mine project In the Guinea gold mine project, equipment such as drum screens, agitation chutes, flat chutes and shaking tables cooperate with each other to form a complete beneficiation process. First, the ore is preliminarily screened by the drum screen to remove large impurities; then, the agitation chute is used to further separate the gold particles; then, the flat chute is used to finely separate the fine particles; finally, the minerals are finally selected by the shaking table to obtain high-grade gold concentrate. This process not only improves the recovery rate and purity of gold, but also greatly reduces energy consumption and environmental pollution.
