Introduction of Inclined Gold Washing Screen
The inclined gold washing screen is a foldable gravity separation equipment designed for alluvial and placer gold ores. It utilizes a combination of gravity flow along an inclined surface and high-pressure water spraying to perform desliming, screening, and the recovery of fine gold particles. Therefore, it is also known as a sloped gold wash screen or inclined gold recovery screen. The equipment consists of an inclined screen frame, a vibrating motor, a vibrating screen/mesh, dual-channel zigzag sluice boxes, and a high-pressure spray system.
Because it performs cleaning and classifying simultaneously, it offers rapid desliming and is suitable for small-to-medium-scale placer gold mining projects. Therefore, it is also a highly efficient, integrated, and modular gold washing and screening equipment. Additionally, this inclined gold washing screen features a compact, durable, and modular design with high gold recovery rates; the interchangeable screen mesh allows it to handle materials of varying coarseness. It is particularly well-suited for placer gold recovery plant operations in riverbeds, dry land, and tailings, while also meeting the needs of mobile gold mining operations that require frequent relocation.
Key Highlights
- Driven by a vibration motor, the material remains loose, ensuring high screening efficiency.
- The inclined flow channel structure ensures smooth and unobstructed flow.
- Integrates ore washing, desliming, screening, and gold recovery into a single process.
- Delivers stable and reliable recovery performance for fine-grained gold.
- Compact structure allows for excellent mobility during relocation.
- High-manganese steel screen surface offers wear resistance and clog resistance.
Key Applications:
- Primary washing, screening, and concentration of placer gold deposits; highly efficient removal of clay and fine sand from the surface of ore material.
- Gravity recovery of placer gold from riverbeds, beaches, and paleochannels.
- Small-scale or mobile placer gold mining in remote areas.
- Recovery of residual fine-grained gold during tailings reprocessing.
- Integration with centrifugal concentrators, shaking tables, and other equipment to form a complete gold processing circuit.
- Replacement of traditional sluice boxes to enhance processing efficiency.
Structural & Principle Of Inclined Gold Washing Screen
Working principle
After entering the inclined screen body through the feed inlet, the material is subjected to high-frequency vibration generated by the vibration motor (via eccentric weights), causing the ore bed to loosen and tumble. Simultaneously, high-pressure water sprays from above continuously wash the ore, breaking up clay lumps and washing away lightweight impurities. Driven by gravity and the water flow, gold-bearing fine sand moves down the inclined screen surface; material smaller than the screen apertures passes through into the underlying sluice or recovery unit, while large waste rock is discharged from the screen tail, thereby achieving ore washing, desliming, and the preliminary concentration of gold particles.
Structural features
- Inclined screen frame: The screen surface is set at a stable inclination angle (15°–30°) to ensure the natural, gravity-fed downward flow of material.
- Round steel screen bars: Features a rod-style design that delivers excellent desliming and classification performance.
- Spray water distribution system: Equipped with high-pressure spray piping featuring adjustable pressure, ensuring a uniform and powerful flow for washing the ore.
- Vibrating motor: Offers adjustable amplitude and frequency to ensure the material is thoroughly loosened and passes effectively through the screen.
- Gold sluice box: The underside of the screen deck is fitted with a sluice equipped with gold-trapping mats and riffles, significantly enhancing the recovery rate of fine gold particles.
- Support frame: Constructed from welded, thick-walled, wear-resistant steel, providing a robust structure.
