A shaking table, or gravity separation table is an essential tool in the mineral processing and mining industry. This equipment is widely used in the mining and mineral processing industries to separate valuable minerals from waste rock. It can handle a variety of materials, including precious metals, coal, and minerals. It mainly operates on the principle of vibration motion to separate materials according to their density and particle size. The key operating principle involves using water flow and vibratory motion to create a fluidized bed to separate particles based on their specific gravity. The process allows heavier materials to settle at the bottom while lighter materials migrate toward the top, resulting in efficient separation. Continuous monitoring of amplitude, vibration frequency, or adjustment of these parameters is critical to maximizing the effectiveness of shaking table tables in mineral processing operations.

working principle

The working principle of the shaking table is that under water and vibration, the particles settle according to their density and size. Key to its effectiveness is its ability to generate specific directional motion, causing dense particles to move along different paths than lighter particles. This shaking action causes heavier particles to settle to the bottom, while lighter particles are carried away by the water flowing across the table. Adjustable slope and water flow create stratification within the material bed as the shaking table continues to run. This layering enables effective separation based on the density of the minerals, with heavier materials gathering in different areas along the bench compared to lighter materials. Additionally, periodic adjustments can be made to optimize the process and achieve higher levels of concentration of desired elements or materials.
