一. 重介選煤成套系列簡介
    eavy-medium cyclone

      本系統分選效果和分選精度高,分選密度調節靈活、范圍寬,可根據要求生產各級精煤。本公司生產有壓、無壓兩產品、三產品重介質旋流器等主洗設備及相關的破碎機、弧形篩、脫介篩、高頻篩、離心脫水機、磁選機、分流箱等設備。

     The cyclone is high in separating efficiency and precision, and can operate with a wide rangeof readily adjustable separating densities for producing different grades of clean coal according torequirements of users. Two different versions are available (pressure-fed/ gravity-fed, 2-product/3-product). The associated equipment for use in combination with the cyclones are also available.These include the coal crusher, sieve bend, medium draining screen, high-frequency vibratingscreen, dewatering centrifuge, magnetic separator and splitter box.

   The JHDC control system developed independently by our company can realize the control ofthe operation of the cyclones in various modes, and perform the process parameters automaticmeasuring and control and production management integrated functions. The control system has an optimized design, flexible configuration and high serviceability. Thanks to the use of modular programming and redundant technologies, the reliability, adaptability and precision of the control system are greatly enhanced.

    The cyclone operates with a medium suspension having a uniform density. The suspension is pumped into the cyclone
under a proper pressure while the raw coal goes into the cyclone by gravity. The cyclone can produce 3 products,i.e. clean coal, middlings and refuse. The cyclone is simple in technological system and low in initial capital cost. The quality of clean coal and middlings can be ensured because the separating density of its 2nd stage can be arbitrarily adjusted
on-line.
    The attractions brought about by feeding raw coal by gravity include higher capacity and separating precision, no excessive size reduction phenomenon, capability to treat a larger feed size range, larger reject extraction capability and higher adaptability. Moreover, the cyclone is lined with OI wear-resistant ceramic tiles for longer service life.
