Abstract: A system for the production of hardened coal agglomerates comprising a first pump for pumping a coal-water slurry and a predetermined quantity of oil or other suitable hydrophobic liquid into an agitated mixing tank, a second pump for pumping the coal-water slurry and partially formed agglomerates from the first mixing tank into a pipeline loop which returns the slurry/agglomerates to the tank, a third pump for removing slurry/agglomerates from the first mixing tank and transporting it to a second mixing tank, means for introducing further fresh coal-water slurry into the inlet of the third pump and/or into the second mixing tank, a fourth pump for withdrawing the slurry/agglomerates from the second mixing tank and transporting the mixture through a second pipeline loop which discharges back into the second mixing tank, and a fifth pump for withdrawing the slurry/agglomerates from the second mixing tank for a recovery of the agglomerates by means of a screen or the like.
