Dry-mixed mortar aggregate drying and screening device

The invention discloses a dry-mixed mortar aggregate drying and screening device, and relates to the field of production of dry-mixed mortar aggregate. According to the device, by arranging a scattering mechanism, materials can be scattered, thus drying is conducted more evenly and thoroughly, by means of related assemblies in a screening cavity, screening is conducted thoroughly, multistage successive screening can be conducted, the structure is simple, a plurality of rotating transverse rods on different driven rotating shafts are arranged in a staggered mode, thus the coverage of the rotating transverse rods during rotation is larger and more comprehensive, by arranging bristle columns, accumulation of the materials on a fixing and supporting cavity is prevented, the sizes of screeningthrough holes formed in adjacent each two or three screening areas are the same, therefore, each two or three screening areas form one corresponding screening set at the same stage, the materials of the corresponding granular
