A rotary impact separator is provided for separating a material. The rotary impact separator includes a body portion comprising one or more walls. The one or more walls define a substantially hollow chamber, an inlet opening, a first outlet opening, and a second outlet opening. The rotary impact separator includes an impact device extending at least partially into the hollow chamber. The impact device includes a shaft that extends within the hollow chamber. The shaft rotates within the hollow chamber. One or more blades are attached to the shaft and contact the material. A diverter is attached to an interior surface of one of the one or more walls. The diverter extends along the shaft and projects from the interior surface toward the shaft. Methods for recovering two or more co-products from a material are provided.

The invention relates to the method 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 a vertical cylindrical body. The rotating disc has plates (hammers) and removable blades of different sizes and configurations. System of pneumatic separation consists of a milling chamber, an air slugcatcher, channels for the milled material, and a chamber of higher pressure. Such construction of the device allows to obtain products of a highest quality, and to improve the separation by dividing the material into three fractions: light, medium and coarse.
