The "mineral processing shaker" is a core separation equipment in the mineral processing industry, especially in gravity beneficiation. It is specifically used to separate and purify useful minerals from gangue (useless impurities) based on the density and particle size differences of mineral particles.

Interpretation of Core Information

1. Essence of equipment: "Precision sorting tool" for gravity beneficiation

The core principle of mineral processing shaker is to utilize the synergistic effect of gravity, table vibration, and water flow to allow mineral particles with different physical characteristics to layer and migrate on an inclined table, ultimately enriching into different products (concentrate, middling, tailings).

High density useful minerals (such as gold, tungsten, tin particles): Due to gravity, they are not easily washed away by water flow and will slowly slide down along the inclined direction of the table, eventually accumulating in the "concentrate area";

Low density gangue stones (such as quartz and feldspar) are easily driven by water flow and quickly move towards the edge of the table with vibration, entering the "tailings area".

2. Key structures and functions

To achieve efficient sorting, the structural design of the mineral processing shaker is clearly targeted, with the main components and functions as follows:

Core Component Function Description

The main working area of the tilted tabletop is usually rectangular, with wear-resistant materials (such as rubber and fiberglass) laid on the surface. Some tabletops are engraved with fine patterns (guiding the direction of mineral flow), and the tilt angle can be adjusted according to the characteristics of the minerals (generally 3 ° -8 °).

The transmission device provides the "reciprocating vibration" power of the table (mostly driven by eccentric shafts), with adjustable vibration frequency and amplitude (usually 100-300 times/minute), determining the migration speed of mineral particles.

Mineral supply and drainage system - Mineral supply: evenly transport the mineral slurry to be sorted (a fluid mixed with water after ore crushing) to the middle of the table;

-Drainage: A sprinkler pipe is installed above the countertop, with controllable water flow intensity, used for "flushing" light particles and assisting in layering.

The bracket and adjustment mechanism support the tabletop, and the tilt angle (horizontal and vertical) of the tabletop can be adjusted to meet the sorting needs of different minerals.

3. Typical application scenarios

Mineral processing shaker is widely used for the separation of metallic and non-metallic minerals, especially suitable for processing fine-grained minerals (usually in the particle size range of 0.074-2mm). Common applications include:

Precious metal ores: rough/fine selection of gold and silver ores (such as sand gold sorting, vein gold reselection);

Rare metal ores: sorting of tungsten, tin, molybdenum, and ilmenite (these minerals have a much higher density than gangue and have outstanding sorting effects);

Black metal ores: purification of manganese and iron ores;

Non metallic minerals: impurities removed from graphite, barite, fluorite, etc.

4. Equipment advantages

High sorting accuracy: It can effectively recover useful minerals in fine particle size, especially for rare and precious metals, with a higher recovery rate than many other gravity equipment;

Strong adaptability: It can adapt to the sorting needs of different minerals by adjusting the vibration frequency, table tilt angle, and water flow size;

Stable operation: simple structure, low energy consumption, and lower maintenance costs in the future (compared to flotation and magnetic separation equipment, there are no complex systems such as reagents and magnetic fields).

In short, the mineral processing shaker is a key equipment in the beneficiation process for "picking out" useful minerals from ores ", and is widely used in the field of fine-grained mineral purification.
