Abstract
Coal particles are agglomerated in pulp water of coal particles by agitating the pulp water in the presence of a binder, which comprises conducting agglomeration in a plurality of zones, the zones being communicated one after another, and transferring the pulp water from one zone to another while agitating the pulp water in each zone and increasing a pulp concentration of the pulp water from one zone to another. Agitating power for the agglomeration is reduced with the successively increasing pulp concentration.
