As a classic gravity mineral separation equipment, the shaking table is widely used to separate fine-grained minerals. It is based on the working principle of the difference in density of mineral particles and realizes the effective separation of minerals through the lateral water flow and the reciprocating motion of the bed surface. In the mineral separation of metal ores such as tin ore, tungsten ore, and gold ore, the shaking table plays an important role, especially suitable for processing fine-grained materials with a particle size of 0.037~2 mm, with the characteristics of high separation accuracy, simple operation, and strong adaptability. The multi-layer shaking table has efficient screening capacity and a high site utilization rate, and as a gravity separation equipment, it is widely used in mineral processing, metal recycling, and other industries.
Multi-layer Shaking Table
A multi-layer shaking table refers to a device consisting of two or more layers of shaking tables, usually including stacked double-layer shaking tables, overlapping double-layer shaking tables and double-linked triple-layer shaking tables. These devices are mainly used to process medium-fine to micro-fine particles and have the characteristics of high separation accuracy.
Multi-layer shaking table is widely used in metallurgy, mining, chemical industry, and other industries, especially in the separation of rare metals and precious metals. Its high recovery rate and enrichment ratio, wear resistance, durability, energy saving, and simple maintenance make it perform well in processing ores of different particle sizes such as coarse sand, fine sand, and ore mud, and it is suitable for the separation of a variety of rare metals and precious metals.
Advantages of multi-layer shaking table
- The inertial bed head has an ingenious structure, and the vertical force is self-balanced. There is no vertical exciting force, so there is no vertical jump. It can be installed on high-rise floors or a seated bracket;
- The suspended structure has extremely low friction power consumption, energy saving and vibration reduction, no bulky foundation, and high-speed and flexible installation;
- The fiberglass bed surface with wear-resistant bed strips is wear-resistant, waterproof, anti-cracking, anti-corrosion, small deformation, less maintenance, and long service life;
- The bed surface is installed in layers on a unified bed frame, which is easy to load and unload, and increases the processing capacity per unit area. The shaking table stroke can be changed by replacing different counterweights;
- The frequency converter can easily change the stroke to adapt to materials of different particle sizes and properties.
Multi-layer Shaking Table Improve The Site Utilization
The multi-layer shaking table can greatly improve the site utilization rate of gravity separation equipment with its vertical design, multiple screening layers, efficient processing, and other characteristics. It enables mineral processing plants to achieve more efficient mineral separation operations within limited land and space by optimizing space and production layout, reducing the number of equipment, and increasing production capacity.
5 Aspects Reflect The High Site Utilization of The Multi-layer Shaking Table
- Vertical layout to improve space utilization
The design of the multi-layer shaking table adopts vertically stacked multiple screening layers. This design can make full use of the vertical space, making the equipment occupy a relatively small area and can handle more materials. Especially when the space in the mining area or mining plant is limited, the multi-layer design can effectively save ground space and improve the utilization rate of the site. - Multi-stage screening, one-time processing of materials of different particle sizes
The multi-layer shaking table is usually divided into several layers, and each layer uses screens with different apertures to classify materials of different particle sizes. This means that the material handling capacity and screening effect of each layer can be improved, reducing the need for secondary screening of materials, thereby reducing the number of equipment and further improving space utilization. - Efficient sorting to improve production efficiency
The working principle of the multi-layer shaking table is to sort materials under the action of shaking and water flow through the gravity difference of the materials. Through multiple screening layers, different materials can be graded and gravity sorted on the same equipment without the need for additional sorting equipment, reducing the number of equipment and floor space, improving production efficiency, and further saving site space. - Simplify equipment layout and reduce floor space
Since the multi-layer shaker can complete multiple screening layer operations in one device, it takes up more space when using multiple single-layer screening equipment under the same production requirements. By using a multi-layer shaker, the equipment layout is more compact, and more screening and sorting tasks can be completed in a limited space. - Strong adaptability, suitable for various mineral processing
The multi-layer shaker is not only suitable for large-scale mineral processing but also can cope with the selection of different ores, tailings, and other metal minerals. Its flexibility and adaptability enable it to work efficiently in different production environments and mining conditions, thereby further optimizing site utilization.
Multi-layer Shaking Table Applied in Malaysian Tin Ore Gravity Separation
As one of the world’s major tin producers, Malaysia’s tin resources are mainly concentrated in Perak and Selangor. Most of the tin deposits here are alluvial, and cassiterite is the main tin-containing mineral, which is associated with gangue minerals such as quartz, feldspar, and mica. Due to the high density of cassiterite and the significant density difference with gangue minerals, gravity separation has become the main method for tin separation in Malaysia.
However, limited space is a common problem in Malaysian tin concentrators. To solve this problem, multi-layer shaking tables are widely used in actual production. Multi-layer shaking tables significantly reduce the floor space and improve the processing capacity by vertically stacking multiple bed surfaces. For example, the floor space of a three-layer shaking table is only 1/3 of that of a traditional single-layer shaking table, but the processing capacity is increased by 2~3 times.
The design of the multi-layer shaking table not only saves space but also optimizes the material transportation process. The slurry is distributed to each layer of the bed through a unified feeding system, and the selected concentrate and tailings are discharged through a centralized pipeline, which reduces the material transfer link, energy consumption, and operating costs. In addition, the sorting efficiency of the multi-layer shaking table is comparable to that of the traditional shaking table, and even better in some cases, because it can adapt to the sorting needs of minerals of different particle sizes by adjusting the operating parameters of each bed surface.
