The invention discloses annular sand production equipment which comprises an obliquely upward feeding screw conveyer, a sand making machine, an annular sealed conveying device, a screening device, a dust removal device, a moistening device and a sand outlet device which are wholly and sequentially connected to form an annular structure, wherein the sand making machine is supported on the ground by a support; the annular sealed conveying device comprises an annular conveyer belt and a cover body arranged at the top of the annular conveyer belt, and a plurality of speed reducing structures are arranged on the inner wall of the cover body; the screening device comprises a vibration sieve, a strong magnetic sieve, a cyclone machine and a horn-shaped sand outlet which are sequentially arranged from top to bottom. The annular sand production equipment eliminates the effect of sand making machine vibration on a sand production line, so that the purpose of prolonging the service life of the annular sand production equipment is achieved.
