Method and device for milling and separation of solids and granular materials including metal containing materials as well as phytogenic materials with high level of silicon in a controlled airflow

A device for milling and separation of solids and granular materials comprising:

• a vertical cylindrical body having a milling chamber with a system of pneumatic separation comprising a chamber of higher pressure created in a gap between a rotating disc and a lower end wall of the milling chamber, wherein the rotating disc has a diameter and is installed on a bearing unit inside the vertical cylindrical body,
• a circular ledge installed along a periphery of the upper surface of the rotating disc,
• an uploading axial slot located on top of said vertical cylindrical body attached to an uploading channel extending into said milling chamber,
• an upper and a lower unloading channels for a milled material of light fraction, wherein both the upper and lower unloading channels for the milled material of light fraction are coupled with an air slugcatcher,
• an unloading channel for a milled material of medium fraction located in a circumferential peripheral part of an upper end wall of the milling chamber,
• an unloading channel for a milled material of coarse fraction located in a circumferential peripheral part of a lower end wall of the milling chamber,
• a conical divider installed inside the vertical cylindrical body with carbide-tipped electrodes welded to a lower edge thereof,
• a plurality of removable hammers radially installed on an upper surface of the rotating disc, with carbide-tipped electrodes welded onto the sides of the hammers, wherein the removable hammers abut the circular ledge installed along the periphery of the upper surface of the rotating disc,
• a plurality of removable blades radially installed on a lower surface of the rotating disc,
• a support system and
• a remote electric motor.
