A device for granulating coarse material is disclosed herein. Examples of course material include pulverulent solids such as powder, grain, or mixtures thereof. The device includes a rotor, a screen, and an automatic distance adjusting unit. The rotor is configured to rotate/oscillate and press the coarse material through the screen in order to produce a granulate with a smaller granulate unit size compared to the coarse material. The automatic distance adjusting unit is configured to adjust a distance between the rotor and the screen.
