Ore Dressing Shaking Table Technical Introduction Ore dressing shaking table, also known as elimination disk, is a kind of equipment that utilizes mechanical vibration and inclined water flow for mineral sorting. It is mainly used for processing fine and micro-fine grained minerals, and is widely used in the beneficiation of tungsten, tin, tantalum, niobium, gold, iron, manganese, chromium, titanium, zirconium and other minerals.
I. Working Principle The working principle of mineral processing shaking table is based on the difference in the movement of mineral particles on the bed surface. The bed surface reciprocates under the action of mechanical vibration, while the water flows laterally along the bed surface. The mineral particles are subjected to the following forces on the bed: Gravity: moving the particles downwards.
Water flow: causes the particles to move laterally along the bed.
Bed friction: impedes the movement of the particles.
Inertial forces: generated by vibration of the bed surface, causing the particles to move longitudinally along the bed surface. Mineral particles with different densities, sizes and shapes, under the combined effect of the above forces, have different movement trajectories, and eventually form fan-shaped zones on the bed surface, thus realizing the separation of minerals.
Second, the structure of the equipment
Mineral processing shaking table is mainly composed of the following parts:
Bed surface.
Usually made of fiberglass or wood, with wear-resistant materials laid on the surface and with rifling strips or grooves to enhance the sorting effect.
Bed head.
Provide mechanical vibration to make the bed do reciprocating motion.
Ore feeding device: feeds the ore slurry into the bed surface evenly.
Water feeding device: Provide horizontal washing water flow.
Slope adjustment device: Adjusts the lateral slope of the bed.
Product receiving tank: collect mineral products with different densities.
Technical features
High sorting precision: It can effectively separate minerals with small density difference.
Large processing capacity: the processing capacity of single equipment can reach several tons/hour.
Simple operation: easy to adjust and control.
Strong adaptability: it can deal with minerals of different sizes and properties.
Environmental protection: no need to add chemicals, friendly to the environment.
Fourth, the application field Beneficiation shaking table is widely used in the following fields: tungsten, tin, tantalum, niobium and other rare metal ores beneficiation. Beneficiation of gold, silver and other precious metal ores. Beneficiation of iron, manganese, chromium, titanium, zirconium and other ferrous metal ores.
Beneficiation of non-metallic minerals, such as quartz, feldspar, fluorite and so on.
Fifth, the development trend ** With the continuous development of mineral processing technology, mineral processing shaking table is also constantly improving and perfecting, mainly reflected in the following aspects: large-scale: to improve the processing capacity of a single piece of equipment.
*Automation: realize the automatic control and adjustment of equipment.
High efficiency: improve sorting efficiency and concentrate grade.
Environmental protection: reduce energy consumption and pollution.
Sixth, the summary of mineral processing shaking table as a traditional mineral processing equipment, by virtue of its simple structure, easy to operate, good sorting effect and other advantages, in the field of mineral processing still plays an important role. With the progress of technology, mineral processing shaking table will move towards the direction of more efficient, energy-saving, environmentally friendly development, and make greater contributions to the development and utilization of mineral resources.
