Abstract

In the continuous sepn. by gravity, of a granular mixt., esp. sand and gravel, into two fractions in a liq. stream by the known technique of supplying the mixt. to a sepg. path and removing a light fraction and part of the liq. from the top and a heav fraction from the bottom of this path, the heavy fraction is discharged from the top of a second flow path, and the flow velocities on the two paths are controlled independently.
