Chain Bucket Gold Dredger

The chain bucket gold dredgers produced by Qingzhou Jinqi Mining Machinery Co., Ltd., a professional manufacturer, serve as the core equipment for large-scale alluvial gold mining in aquatic environments. Featuring a hydraulically driven chain bucket system, these dredgers are well-suited for hard ore layers (such as cobbles and hard soils) and operate effectively in shallow to moderately deep water zones (1.5 to 20 meters). They boast strong excavation capabilities, high separation efficiency, and low operational costs. Currently, Jinqi is offering factory-direct sales of its chain bucket gold dredgers.

Core Structure and Working Principle

The chain bucket gold dredger consists of five main modules:

Excavation System:

Comprising chain buckets, chains, underwater arms, and drive motors, this system utilizes hydraulic motors to deliver high torque, enabling it to crush cobbles with a diameter of ≤300 mm and continuously excavate sand-gravel mixtures.

Ore Processing System:

Adopting a "three-stage separation" process:

Primary Screening: A rotary drum screen removes large impurities.

Secondary Roughing: A sluice or jig recovers coarse gold particles.

Tertiary Concentration: A centrifugal concentrator enriches fine gold and microscopic gold particles.

Tailings Disposal System:

Gravel and tailings are transported away from the operation area via belt conveyors or sluices to prevent siltation.

Water Supply and Conveyance System:

A water pump supplies water for ore washing, while a combined sluice conveys the ore slurry to the separation equipment.

Power System:

Powered by diesel generators or shore-based electricity, it drives the chain buckets, separation equipment, and auxiliary systems.
