ABSTRACT:
A method and apparatus for classifying solids and transporting a solids-laden fluid containing large particle size solids which will tend to plug a tubular transport means and small particle size solids which will pass through the transport means without plugging, including passing the solids-laden fluid through a screening means and removing therefrom large particle size solids having a maximum dimension greater the internal diameter of the fluid transport means while passing through the screening means the solids-laden fluid containing small particle size solids having a maximum dimension smaller than the internal diameter of the fluid transport means and thereafter passing the solids-laden fluid containing the small particle size solids through the fluid transport means.
