Tenders are invited for Supply of spray pipes for hydrosizer
The excess water and minus-63 pm material is overflowed and piped to thickeners while the cyclone underflow feeds a hindered settling classifier or Hydrosizer
The smaller particle sizes then move to a hydrosizer
circuit which is a compartment filled with water that lifts the finer particles upward, with the heavier particles settling to the bottom of the unit.
The fraction below 1 mm was upgraded at the NAGROM laboratories in Perth Australia where clays and quartz sand were rejected using two stages of hydrosizer
, with the final underflow product upgraded using a Wilfley Table.
Screen undersize is if pumped to a battery of 15" Krebs cyclones, the overflow reporting to the pre-flotation thickener and the underflow gravitating to a six spigot Stokes Hydrosizer
. The six fractions from the hydrosizer
are then fed to 164 Derrick and Holman tables where a primary table concentrate is recovered.
Coal is fed into a hydrosizer
, which uses a stream of water to isolate and remove the heavier, coarse impurities.
Tenders are invited for Erection of hydrosizer
and its relating equipments
Last year we launched a slurry pump with a longer lasting wear liner and this year are introducing a Round Hydrosizer
to the market and introducing a standard line of modular plants that will be readily available to producers.
The chief disadvantages of coal spirals of relatively low unit capacity and high cutpoint, have led to the trials and recent installation of the Stokes Hydrosizer
(MM, May 1995, p.292), or teetered bed separator (TBS).
Oversize is recycled and undersize pumped to the hydrosizer
In 2011, McLanahan was able to custom-engineer a system that utilizes hydrocyclones, a hydrosizer
(or density separator), pumps and dewatering screens.
The company produces its own proprietary range of equipment, including hydrocyclones, thickeners, sieve bends, scroll-type fine coal centrifuges and the Stokes Hydrosizer
