The study of nucleation and granule formation in a bed of fine-grained material during the phase of batch damping in the process of periodical disc granulation was conducted. The study was carried out on laboratory disc (diameter - 0.5 m), with the use of constant disc filling with powder material, constant slope angle 50 between the disk axis and level and constant rotational speed of device. Foundry bentonite was used as the examined material and distilled water as a binding liquid. The binding liquid was added in the form of droplets having constant size. The size of droplets was changed in the range 2.44.9 mm. The influence of number and size of binding liquid droplets delivered to bed, as well as of their delivery height on the size distribution of nuclei generated in the dumping phase was determined.
