Abstract: The invention relates to means for the autogenous grinding, separation and drying of various solid materials in a continuous process and can be used in many branches of industry. The technical result consists in creating a high-speed, powerful and at the same time energy-efficient, simple and reliable device and method for breaking up an initial stock and simultaneously drying particles of the ground stock. The technical result is achieved by feeding an initial stock into a grinding working area, grinding the initial stock and drying particles of the ground initial stock and discharging the ground and to a certain extent the dried particles of the initial stock outwards, with the initial stock being fed in and the dried particles of the ground stock being discharged by rotation of working flywheels.
