The invention discloses recycled aggregate pretreatment equipment. The recycled aggregate pretreatment equipment comprises a pretreatment system, a spraying system and a liquid supply system. The pretreatment system comprises a wetting box, a rolling net drum horizontally arranged in the wetting box in the axial direction, a driving part for driving the rolling net drum to rotate, a receiving bin, and a storage yard, wherein a feeding channel is formed in one end, in the axial direction, of the wetting box, a discharging channel is formed in the other end, in the axial direction, of the wetting box and connected with the receiving bin, and a spiral blade used for guiding recycled aggregate from one end of the rolling net drum to the other end is arranged in the rolling net drum. The spraying system is arranged above the storage yard and used for conducting spraying on recycled aggregate in the storage yard. The liquid supply system is used for providing liquid sources for the wetting box and the spraying system respectively. The recycled aggregate is uniformly pre-wetted through rotating and screening of the rolling net drum, and meanwhile small particles not meeting the particle size requirement, surface-adhering micropowder, impurities and the like in the recycled aggregate are removed; the spraying system conducts spraying on the recycled aggregate in the storage yard, and it is guaranteed that the pretreated recycled aggregate in a surface-wetted state without clear liquid so that the storage quality of the pretreated recycled aggregate can be guaranteed.
