Abstract:

The dense medium beneficiation playing a key role in coal dressing industry has been commercially applied in the world since the 50s and in Vietnam since the 70s of last century. For years, Institute of Energy and Mining Mechanical Engineering - Vinacomin has designed and manufactured some dense medium cyclones and major components of the vertical wheel dense medium separator CKB-20 (manufactured by Soviet Union) provided to domestic coal dressing factories, in 2016-2017, for the first time, the Institute has successfully designed and manufactured 2 vertical wheel dense medium separators MTHP-20 and MTHP-16, providing tó the investment project -of Dressing factory Vàng Danh 2, with capacity of 2 million tons per year.
