[0002] Principle of pneumatic separation: The pneumatic separation defines the action of floating and separating certain material in an air flow. By setting a certain airflow velocity, it makes the lighter part of the materials, with the lower suspending speed than the set speed, move upwards, the heavier parts move otherwise downwards, so the materials are essentially separated into two parts of the lighter and the heavier. This principle is widely applied in various industries, such as CN201454852 U

the present invention is achieved by the following technical solutions.
[0007] The shared upper side wall of the separation silo is communicated with the discharge silo thereof through a communication port, where an air curtain is disposed to isolate both silos from each other. The discharge port is disposed at the bottom of the discharge silo. A suction outlet is mounted on the top of the separation silo, at the lower part of the side wall thereof is disposed a feeding port, which is precisely facing towards the end of the belt conveyer. At the lower part of the separation silo is arranged a vibration trough, under which is disposed a damper plat, underside of which has a air inlet just located at the bottom of the separation silo. A rejection outlet is installed beneath at the end of the vibrating trough.
[0008] The mesh belt conveyer is horizontally arranged in the separation silo and the discharge silo, compromising an air curtain taking the structure with a communication port, where an auxiliary air inlet is provided, on the top of which a series of air holes disposed, which is vertically facing the mesh belt conveyer.

[0016] The material attached on the surface of mesh belt conveyer lost the negative pressure suction force and positive pressure lifting force from underside after entering into the discharge silo, separates itself with the mesh belt conveyer under its own gravity, and falls to the discharge outlet in a parabolic path, resulted by the inertia of mesh belt conveyer movement. A rotating brush mounted at the end of mesh belt conveyer, which is tangential to thereof, make relative motion reversely against the mesh belt conveyer driving. The rotating brush brings down all the materials attached to the mesh belt conveyer, to the discharge outlet.
