A brewer's spent grain (BSG) grinder includes a charging tank connected to a grinding unit, the charging tank being equipped with a device for BSG moistening, and the grinding unit having an outlet for discharging grinded BSG. The grinding unit includes a stator and a rotor located coaxially with a gap defined between their working surfaces. A device for mixing and moving a mixture into the gap is fixed on a central part of an upper side of the rotor. A device for discharging grinded BSG is located under the rotor. The rotor is configured to allow staged grinding of BSG to obtain coarser and finer fractions of BSG at upper and lower stages of the rotor respectively. An upper part of the rotor is equipped with blades located around a circumference of the rotor, an outer surface of each blade being part of the working surface of the rotor.
