The invention which relates to a sand making machine belongs to the technical field of sand making machines. The machine comprises a machine body; a charging grid frame is fixedly arranged on the top of the machine body; at least one working layer formed by a sand grinding mechanism is arranged in the machine body under the feeding grid frame; the sand grinding mechanism comprises a group of tooth beds which slidingly cooperate with each other and are arranged in the machine body, and tooth plates fixedly arranged on the tooth beds; sand grinding cavities with trapezoid structures are formed by the gaps between the tooth plates corresponding with adjacent tooth beds; the sand grinding cavities are opposite to the feeding ports of the feeding grid frame; and the tooth beds back and forth grind under the driving of a driving mechanism connected with the tooth beds. By adopting the machine of the invention to make sand, the sand making rate can reach above 80%, and particle sizes of the sand can reach below 4mm;
