Definitions

  • the invention relates to a method for separating particles in hydrous slurry.
  • the present invention relates to a hindered-bed separator or hindered-bed settler or similar separator or settler apparatus (hereinafter “hindered-bed settler”) to partition solid particles in a hydrous slurry or pulp into two or more fractions containing particles of different size and density.
  • hindered-bed settler to partition solid particles in a hydrous slurry or pulp into two or more fractions containing particles of different size and density.
  • Many sizing and classifying methods employ gravity of solid material in hydrous slurry with an incoming feed containing the material encountering an upward teeter water flow.
  • the variation in size and/or density will result in heavier particles falling to a lower level of the hindered-bed settler and lighter particles being uplifted to an overflow level of the hindered-bed settler thus affecting the desired separation.
  • hindered-bed settlers are based on even distribution of a controlled amount of teeter water into an in inner space of the body of the hindered-bed separator with teeter water distributor means arranged in the inner space of the body of the hindered-bed separator.
  • teeter water is pumped into teeter pipes of the teeter water distributor means from one side only, but if the water is "dirty" and contains for example much fine solids, the teeter water pipes will get clogged because of the fine solids settling at the end of the teeter pipe where the flow velocity is lowest.
  • the aim of the invention is to solve the above-identified problem.
  • a first alternative of the method for separating particles in hydrous slurry of the invention is characterized by the definitions of independent claim 1.
  • a second alternative of the method for separating particles in hydrous slurry of the invention is characterized by the definitions of independent claim 6.

  • a teeter water discharging means that is in fluid connection with the teeter water distributor means.
  • This means for example that a certain amount of teeter water is fed into the teeter water distributor means. This amount can for example be the double compared to the amount actually used for teetering in the hindered-bed separator, so the other half just runs through the teeter water pipes of the teeter water distributor means inside the hindered-bed separator.
  • both the intake pipe for feeding teetering water to the teeter water distributor means and the return pipe for leading teetering water from the teeter water discharging means is provided with a flow measuring means, such as a flow meter, for measuring the flow before the hindered-bed separator and respectively for measuring the flow after the hindered-bed separator.
  • a flow measuring means such as a flow meter

  • the method includes a step for feeding between about 110 % to about 200 %, for example between about 125 % to about 150 %, the amount of teeter water 9 into the teeter water distributor means 7 of the amount of teeter water 9 that is needed for the separation process performed in the inner space 3 of the body 2 of the hindered-bed separator 1.
