Pellets having uniform size and excellent strength properties are manufactured without fluctuations in production from finely-divided moist material by rolling nuclei of substantially mutually identical size in at least one pellet-rolling circuit in the presence of the finely-divided moist material, to form pellets having at least one layer of said material surrounding respective nuclei. A pre-determined quantity of the pellets formed during a rolling operation and comprising pellets which, during said rolling operation have obtained the largest diameter, is continuously removed as product pellets from said pellet-rolling circuit, while the remaining pellets formed during the rolling operation are returned to the rolling portion of the circuit for renewed rolling therein, the supply of finely divided moist material and of the nuclei to the pellet-rolling circuit being adjusted so that the diameter of the product pellets and the amount of material in the pellet-rolling circuit are maintained substantially constant.
