An Introduction To The Prospect Of Concentrators
First, lets talk about the concentrator itself- one of the ore beneficiation
. The high efficiency concentrator is suitable for dehydrating the ore concentration and tailings. It can make the mash of 20-30% rise to 40-70%. It is widely used for melting, chemical, coal, non metal concentration, environment protection industry, etc. It is not only sedimentation equipment but also a new type dehydrating equipment with the mash percolate features.
(1) Adding flocculating agent to enlarge the diameter of the deposit solid grain, speed up the deposit.
(2) Set the lean board, reduce the mash deposit distance, and increase the deposit area.
(3) Have effect on flocculating. Percolating, compressing and dealing quantity of the slurry deposits.
(4) Equipped with the perfect automatic facility.
Concentration is a process by means of gravity centrifugal force or physical and chemical effects of pharmaceutical to realize agglutination of solid particles in suspension, thereby enhancing the solid phase concentration in suspension. This process is widely used in the concentration process of ferrous metals, nonferrous metals, rare metals and non-metallic. Nowadays, the main equipment to achieve this process is concentrator. Due to its easy operation and relatively low maintenance costs, it is widely used in various industrial sectors. In the mineral processing equipment, concentrator is mainly used for the concentrate product concentration; tailings recycled water handling as well as dehydration condensed of intermediate products.
The ore processing is the most important aspect of the whole mineral production and the crucial sector in the mining enterprises. Generally, the large-scale mining enterprises are the resource companies integrating mining, elections and smelt. The physical or chemical methods are used to separate the useful mineral from the unwanted mineral or harmful minerals. The ore processing is a process to separate a variety of useful mineral from the mineral, which is also called as "mineral processing". The ore processing is also widely used in the coal industry. The main task of the coal dressing is to rule out the gangue, pyrite and other impurities mixed with the raw coal in order to reduce the ash and sulfur content of the coal. The common methods of ore processing include gravity separation and the flotation.
Currently the concentrator home and abroad is basically in a stable stage, and the development and improvement are not significant. The concentrators used in the mineral processing plant are major of center-drive, because of their reliable operation. Some mineral processing plants add inclined plate in the small and medium-sized concentrator, in order to improve the processing capability of unit area. Moreover, the multilayer (3-5 layers) concentrator is researched in order to reduce floor space. Many countries have produced complete series and more specifications. According to the structural features, they can be divided into several types:
(1) Center shaft driving inspissations concentrator: generally the small diameter concentrator is with such a structure. Its special cylinder leaves the rake frame rotating through the center of rotation axis. The diameter of such concentrator is generally no more than 20 to 25 meters.
(2) Center drive concentrator: structural features of this kind of concentrator is that in the center of the concentrated pool there are reinforced concrete columns above the surface, so as to support the machine, Center Drive drives harrow frame to rotate. The diameter of this type of concentrator is not too large; usually about 20 meters, but the maximum can reach 50 meters or more.
With the improvement of the science and technology and the increase of the demand of the raw material and energy of human, the technical level of the ore processing will continuously improve greatly and its range of applications will be widened.
