The invention discloses a rotary screen net device for the production of a calcium-zinc stabilizer. The device comprises a shell, wherein the top of the shell is provided with an upper cover, the leftand right sides of the top of the upper cover are symmetrically provided with feed ports, the bottom of the shell is provided with a base, the left and right sides of the top of the base are providedwith outer baffles and inner baffles respectively, the middle of the top of the base is provided with a case, the bottom of an inner cavity of the case is provided with a driving motor, a power output end of the top of the driving motor is fixedly connected with a rotating shaft, the top of the rotating shaft is provided with a rotary screen, the top of the rotary screen is provided with a vibrator, the outer wall of the vibrator is sleeved with a protection cover, qualified product discharge ports are formed between the left and right sets of the outer baffles and inner baffles respectively,and inferior-quality product discharge ports are formed between the inner wall of the shell and the two sets of the outer baffles respectively. The rotary screen net device for the production of thecalcium-zinc stabilizer has the advantages that residual large-grain inferior-quality products are separated and collected from a screen net during filtering and screening of the powdery calcium-zincstabilizer, the filtration effect of the screen net is ensured when the rotary screen works continuously, and the production efficiency is improved.
