Dry Land Gold Panning Vehicle Gold Screening Equipment

一. Working Principle

1. Raw material pretreatment: The gold-bearing ore is put into the silo by a loader or excavator, and the large impurities are initially filtered through the grid screen.

2. Scrubbing and screening: The material enters the scrubbing cylinder (equipped with some models), and the clay is removed by high-pressure water washing; then it enters the drum screen and is classified according to the particle size (usually no more than 1 cm is effective for ore dressing).

3. Gravity gold selection: The fine slurry flows into the ore dressing module (such as chute, centrifuge), and the high density of gold is used to achieve enrichment, and the enrichment ratio can exceed 1000 times.

二. Core structure and component modules

The gold panning car adopts a modular design to ensure complete functions and flexible mobility:

• Power system: Diesel engine drive (20-25 kilowatts), dual-channel output drives the screening equipment and water pump system respectively, and no external power supply is required.

• Screening system:

Drum screen: diameter 1.3 to 1.6 meters, with a reamer inside to extend the material travel and improve screening efficiency; the screen is equipped with multi-directional flushing holes to prevent clogging.

Scrubber (some models): Strongly separate clay and ore to increase the exposure of gold particles.

• Ore dressing module: Supports on-demand configuration, including:

Fixed or agitated chute (basic type, low cost)

Centrifugal gold concentrator (high recovery rate, suitable for fine gold)

Nelson concentrator (high-end model, recovery rate greater than 94%)

• Mobile chassis: wheeled towing design, solid tires are wear-resistant and damage-resistant, traction speed does not exceed 15 kilometers per hour, minimum turning radius is 4.8 meters, and can adapt to complex terrain.

三. Diversified gold selection system configuration

Users can choose expansion modules according to the characteristics of the ore:

1. Basic type: fixed chute, suitable for coarse gold, low cost but requires manual cleaning of compaction.

2. High-efficiency type:

Agitator chute: mechanical anti-compaction design, automatic ore cleaning.

Centrifuge: The recovery rate of fine gold particles (0.01 to 1 mm) is significantly improved, and the concentrate yield is about 0.1%.

3. Combined process: drum screen plus vibrating chute plus centrifuge three-stage recovery, adaptable to complex ore bodies.

四. Highlight product advantages

• Convenience of mobility: The integrated frame supports the rapid transfer of tractors to meet the needs of multi-point mining.

• Strong adaptability:

Terrain: Dry land, river beach, and tailings pond can all operate.

Ore: Compatible with placer gold mines and rock gold tailings, allowing fluctuations in feed concentration.

• Low operating costs: Diesel power reduces energy dependence, and modular design facilitates maintenance.

• High recovery rate guarantee: Dual-channel recovery technology separates coarse gold and fine gold to reduce gold loss.

五. Practical application scenarios

• Rivers and dry land: Directly process surface gold mines to save ore transportation costs.

• Tailings redevelopment: Recover single gold from abandoned vein mines to improve resource utilization.

• Overseas mining: The compact design is suitable for export and has been used in gold mining ships in Africa, Southeast Asia and other places.

六. Purchase suggestions

• Small mining areas: It is recommended to choose a model with a processing capacity of 50 cubic meters per hour, equipped with an agitator chute, with a budget of about 80,000 to 120,000 yuan, such as the Qingzhou Guancheng Heavy Industry series.

• Large projects: It is recommended to choose a 500-ton per hour model, which can be used with a centrifuge. The recovery rate can exceed 94%, and the investment is about 250,000 yuan, such as Qingzhou Keda ore sand equipment products.
