Environment-friendly construction waste treatment device

The invention relates to the technical field of construction waste treatment, in particular to an environment-friendly construction waste treatment device. The device comprises a treatment box, a discharge hopper is arranged at the treatment box, the upper and lower parts of the discharge hopper are opened, and the inner diameter is gradually reduced from top to bottom; a rotatable material distributing cone is arranged at an opening in the lower end of the discharging hopper and provided with a conical surface with the diameter gradually increased from top to bottom, a material distributing gap is formed between the conical surface of the material distributing cone and the opening in the lower end of the discharging hopper, and a permanent magnet is arranged on the conical surface of the material distributing cone. By means of the structure, the metal waste and the concrete waste can obtain different initial centrifugal speeds at the material distribution cone, so that the metal waste and the concrete waste
