A concurrent-flow and sieving drying device for materials can be widely applied in the fields of chemical industry, coal, building materials and metallurgy, and is formed by a casing as well as a feed hopper, a discharge hopper, a hot airflow inlet, a hot airflow outlet, a crossed pipe bundle, a flow guide pipeline, a grating, a power device and a bracket which are mounted on the casing, and a heat insulation layer is wrapped around the casing. After being fed into the device, the materials to be dried instantly exchange heat with the hot air flow in the crossed pipe bundle as well as the flow fed into the casing in the regions provided with the crossed pipe bundle, and then the moisture evaporates and the temperature of the air flow is reduced. Next, heat exchange is conducted continuously in the material waterfall position of the sieving grating until the materials reach the standard of drying, and then the materials and the air flow leave the system from the bottom of the system. The whole device is in the
