This invention discloses a continuous, high-efficiency, automatic dry-mixed mortar preparation equipment, relating to the field of mortar preparation technology. It includes a sand drying device and a feeding hopper. A sand particle screen is installed on one side of the sand drying device, and a screw conveyor connects the sand drying device and the sand particle screen.
