The waste sand can be recycled to reduce the production cost. In this paper, the wet reclamation technology of phosphate modified animal glue used for foundry binder was studied. The results show that: the regeneration process is two times of continuous regeneration, the water sand ratio is 2:2.2, the regeneration time is 6min, the speed is 250rrmin, the ignition loss of the reclaimed sand is 0.30%, the mud removal rate is 82.5%, the average fineness is 51, the tensile strength of the reclaimed sand is 2.59MPa, which is similar to the original sand, and the wet reclamation effect is better.
