The invention discloses a burn-free spherical attapulgite fly ash ceramsite. The key point of the technical scheme is as follows: the burn-free spherical attapulgite fly ash ceramsite comprises attapulgite clay tailing powder, fly ash, bentonite tailing powder, stone ash and cement. The ingredients of the burn-free spherical attapulgite fly ash ceramsite are mixed, granulated, cured, screened and packaged to obtain the burn-free spherical attapulgite fly ash ceramsite. The burn-free spherical attapulgite fly ash ceramsite is of spherical shape, has rough and hard surface and has a lot of fine pores in the interior; and the burn-free spherical attapulgite fly ash ceramsite is a construction ceramsite with high strength, low thermal conductivity, stable chemical property, durability and good heat insulation and sound insulation effect. The comprehensive utilization of fly ashes and tailings in producing the burn-free spherical attapulgite fly ash ceramsite is beneficial for increasing the resource utilization r
