Drum screen: efficient separation of sand and gold

Drum screen is one of the commonly used equipment in the process of gold panning, mainly used for the preliminary separation of sand and gold. Its working principle is to screen sand and gold particles through the rotation of the drum. The design of the drum screen usually includes multiple layers of screens, and screens with different apertures can separate particles of different sizes. This equipment is suitable for placer ore with high gold content, and can quickly remove large pieces of sand and gravel, leaving fine sand with high gold content. The advantages of the drum screen are simple operation and convenient maintenance, which is suitable for small and medium-sized gold panning operations.

Centrifuge: Efficient concentration of gold

Centrifuge is a device that uses centrifugal force to separate gold, especially suitable for the extraction of fine-grained gold. Its working principle is to separate gold particles with higher density from sand and gravel through the centrifugal force of high-speed rotation. The advantage of the centrifuge is that it can efficiently concentrate gold, especially suitable for processing placer ore with low gold content. In addition, the centrifuge has a high degree of automation, which can greatly reduce manual operation and improve work efficiency. It should be noted that the centrifuge has high requirements for the particle size of the placer, and usually needs to be pre-processed with other equipment.

Shaking table: fine separation of placer gold

A shaking table is a device that uses the principle of gravity sorting, mainly used for fine separation of placer gold. Its working principle is to separate the placer gold from the gravel by stratifying the particles of different densities on the bed surface through the vibration and tilt angle of the shaking table. The advantage of the shaking table is that it has high separation accuracy and can effectively recover fine-grained placer gold. In addition, the shaking table has a wide range of applications and can handle various types of placer ores. However, the processing capacity of the shaking table is relatively low, which is suitable for small-scale or refined gold panning operations.

Spiral chute: low-cost and efficient extraction of placer gold

The spiral chute is a simple and low-cost gold panning equipment, especially suitable for processing placer ores with low gold content. Its working principle is to use the rotation of the spiral trough and the action of gravity to stratify the placer gold and gravel. The advantages of the spiral chute are low equipment cost and low energy consumption, which is suitable for large-scale placer processing. In addition, the maintenance cost of the spiral chute is low, which is suitable for long-term use. However, the separation accuracy of the spiral chute is relatively low and usually needs to be used in conjunction with other equipment.
