Abrégé

The invention relates to the method and device for milling and separation into fractions of solids and granular materials in a controlled airflow. The device for milling and separation of solids and granular materials consists of a round milling chamber with a system of pneumatic separation comprising of a vertical cylindrical body that has an uploading slot for solids and granular materials and unloading channels for the milled products of light, medium and coarse fractions. A rotating disc and a conical divider are located inside the vertical cylindrical body. The rotating disc has removable hammers and removable blades of different sizes and configurations. The system of pneumatic separation consists of a milling chamber, an air slugcatcher, channels for the milled material, and a chamber of higher pressure. Such a construction of the device allows to obtain products of the highest quality, and to improve the separation by dividing the material into three fractions: light, medium and coarse.
