Physical shaping device and method for building solid waste recycled aggregate

The invention discloses a building solid waste recycled aggregate physical shaping device which comprises a building solid waste aggregate shaping cylinder assembly, an aggregate shaping shaft rod assembly is arranged in the building solid waste aggregate shaping cylinder assembly, and a closed discharging assembly is arranged at the top of the building solid waste aggregate shaping cylinder assembly. The aggregate shaping shaft rod assembly forms a coaxial acceleration reverse stirring shaping structure or a coaxial acceleration same-direction centrifugal discharging structure in the building solid waste aggregate shaping cylinder assembly, and the closed discharging assembly forms a directional transposition type closed discharging structure on the top of the building solid waste aggregate shaping cylinder assembly. Meanwhile, a negative-pressure dust collection structure for timely extracting and collecting old mortar and surface accumulated dust is formed at the bottom of the building solid waste aggregat
