Cement pavement crushing and regenerating machine and method

The invention discloses a cement pavement crushing and regenerating machine and method in the technical field of road regeneration, and aims to solve the problems that in the prior art, the cement pavement regeneration construction efficiency is low, the number of procedures is large, and regenerated material gradation control is unstable. The method comprises the steps that the crushing strength of a rotor mechanism and a housing assembly on cement fragments is adjusted by controlling the distance between a crushing housing and the rotor mechanism, then the particle size of the cement fragments is controlled, the discharging particle size is controlled through a screening rake, and the cement fragments with the proper particle size are discharged from a screening opening; cement fragments with the particle size larger than that of the screening opening are limited in the rotor mechanism and the housing assembly to be further crushed. Integrated crushing and regeneration of a single cement pavement crushing a
