3GHMC-Series Gravity-Fed 3-Product HM Cyclones

  Chacrateristics
♦  One of the world's most advanced innovativedevices (with numerous patents invented by GTC) in coal prep industry
♦  Two vessels in series (see the sketch) – A cylindrical one for 1st-Stage HM separation at a relatively low density and a conic cyclone for 2nd-Stage HM separation at an elevated density (e.g. > 2.0 kg/L)
 ♦  High effectiveness in non-deslimed and non-sized separationof a variety of coals with three products (clean coal, middlingsand refuse) in one set of unit and at one relatively-low heavy medium density
♦  Gravity-Fed approach– Being different from conventional approach (a mixed coal-media pulp being pumped to a HM Cyclone), this type of feeding significantly reduces size degradation, power consumption, and mechanical wearing
♦  High separation efficiency – Ep1 = 0.02~0.03kg/L, and Ep2 = 0.03~0.05kg/L for 0.5mm fraction; for the 0.5~0.25mm fraction, Ep= 0.065~0.09kg/L
♦  High reliability for over 9000 working hours due to the use of hi-wear-resistant lining with Reaction-Bonded SiC and Cr-material
♦  Primary selecteddevice for HM Separation in China's coal prepindustry(e.g. > 400 plants)
♦  11 product models of the series with the capacities rangedfrom 40 to 650 TPH (up to 800~1000 TPH for deslimed raw coals)
♦  Top feed particle size 110mm for the Ø1500mm HM Cyclone
  Structural Characteristics
♦  There are three outlets for clean coal, middlings and refuse, respectively.
♦  Use a cylindric vessel in primary-stage section - In the vessel, media are homegeneous
in density and insensitive to media change, which is good for separation.  
♦  Use a cylindric-pyrmid in secondary section - This structure is good to increase
the actual separation density, and thus to minimize misplacement of middlings into
refuse.
♦  Raw coal and heavy media are fed separately into the cyclone.
♦  Use a combined approach by either altering the apex size of the secondary-section
or adjusting the depth of the vortes finder of the secondary section.
♦  It is lined with corundum material.
