China's Coal Dense Medium Cyclone

The 1990s was the era of rapid development in China’s dense-medium coal preparation technology. And the washed coal volume was minimized. As a result of the rapid development of the coal preparation technology through the dense-medium cyclone.
The development momentum of China’s dense-medium coal separation first came from the state environmental protection policy and the sustainable development strategy of the national economy. The Chinese government recognizes coal as basic energy, and therefore strives to enhance the proportion of high quality coal, increasing developmental efforts of clean coal technology. The Chinese government encouraged and supported the development of the coal beneficiation technology and promoted the adoption of dense-medium coal beneficiation methods of high efficiency.
In the late 1990s, due to the promotion of policies and markets, China’s research and development units did a lot of research work in equipment, technological process, plant structure and efficiency.
China’s state owner mining institute Coal Preparation branch, was recognized as China’s leading enterprise in the field of coal preparation. They obtained a number of achievements in scientific research, leading the progress of China’s coal preparation technology. Then particularly did a lot of work in the development of the dense-medium cyclone. Thereby the plant investment and operating costs were greatly reduced, and also production management and separation efficiency was significantly improved. This provided a good foundation for the massive industrialized promotion of the coal beneficiation technology of China’s dense-medium cyclone.
After the problems, such as complicated processes and high power consumption was solved. The dense-medium cyclone, especially three-products dense-medium cyclone proved to be high in separation efficiency, and can be used to simplify the coal beneficiation process and reduce the amount of equipment and its footprint on the site occupied by the coal beneficiation plant. This greatly lowers the production cost and therefore it captured the Chinese market.
The continuous development of the large-diameter dense-medium cyclone has a far-reaching significance for the development of coal beneficiation technology.
High-level optimized design and high-precision processing technologies ensure the products quality. Simple structures and small physical footprint considering the large capacity and high separation efficiency. For the lining we used the highly wear resistant composite ceramic materials developed by FavorSea, which makes it extremely durable. This ensures the service life of the cyclone equipment. These measures have been taken for all wearing positions and wearing parts.
We include the most advanced and reliable intelligent control system, with an advanced coal preparation process monitoring system. This system features:
We only make use of the top brands of parts in China to ensure the excellent reliability and mechanical performance of the equipment. We used the best industry standard CAD software like Fluent, Pro/E and Solidworks for optimal design and insight into the design of our products. We design and manufacture customized equipment for customers based on their specific requirements.
We take into account on-site spatial environment or factory structure restrictions and also comprehensively consider the site application in different use scenarios, such as:
We also take into consideration the different coal preparation characteristics of coal like size, consistency and the different requirements for our products.
Our products can be customized to any need our clients might have. We have more than 20+ years experience in implementing these technologies on site. And we fully support our products after installation.There are no restrictions on what we can do in terms of product use and integration and we can objectively recommend or design products with proper technologies to spec for our clients by fully considering the design capacity of the coal beneficiation plant, coal quality and requirements of our products.
The multi-medium series of gravity feeding three products dense medium cyclone is the new generation of high-end technical products developed by FavorSea. Our products alleviate problems during any large-scale development of cyclones.
During the countless experiments by our research workers this product is the key equipment used for separation of 0-100mm size fraction raw coals.
Advantages include low energy consumption, long service life, convenient adjustment, low degradation rate of coal and easy model selection of supporting equipment. This means less initial investment, small occupied footprint, simple technological processes and low costs.
Feed the qualified dense medium suspension of single density into the cyclone under the proper pressure. The raw coal is fed into the cyclone by relying on gravity to separate clean coal, middling and refuse successively, which has simplified the process and reduced investment.
