Product Overview
The bucket gold dredger is a high-efficiency water sand gold mining equipment with the bucket as the core digging part, integrating multi-stage screening, gravity separation and purification. It consists of double-hull floating box, bucket conveying system, gold mining separation system, drive system, control system and other components. It excavates underwater sand gold-bearing materials through buckets, and finally obtains high-purity sand gold through conveying, screening, separation and purification. The equipment covers small, medium and large specifications, can adapt to mobile and fixed operation modes, and has the advantages of sturdy structure, stable operation, wear resistance and energy saving, intelligent control, strong adaptability, safety and environmental protection, and easy operation. It mainly features high gold recovery rate, high operation efficiency and wide water area adaptability. It can operate alone or with a complete sand gold mining production line, and is widely used in various sand gold mining points such as rivers and shallow seas. It can process a variety of sand gold-bearing materials with low energy consumption, easy maintenance and prominent economic benefits. It is the core preferred equipment for large-scale and efficient sand gold mining, realizing integrated operation of digging, gold panning and purification without additional beneficiation facilities.
