An electric vibration screening feeder which is used for mineral processing in mines belongs to the technical field of preparation equipment and comprises a trough, a vibration isolation coiled spring, a boom, a main vibration plate spring and a vibration generator. The electric vibration screening feeder is improved. The baseboard of the trough is formed by connecting a material carrying plate with a screening plate, and the material carrying plate is located at the rear portion of the trough and opposite to a feed opening of a material bin. The screening plate is located at the front portion of the trough, screening holes are evenly distributed on the screening plate, the front end of the screening plate is opposite to a ball grinding mill feeding belt, and a material hopper below a screener is arranged below the screening holes of the screening plate. By means of the electric vibration screening feeder, after materials are screened by the screening plate, products below the screener are processed in a wet-type preconcentrated mode, primary concentrate is conveyed to a section of a classification device through a slurry pump, products on the screener are brought to the ball grinding mill to process through the ball grinding mill feeding belt. The electric vibration screening feeder simplifies the primary screening process, optimizes the equipment configuration, and provides convenience for the transformation of the wet-type preconcentration process. At the same time, fine grained materials can be screened out, and thus the phenomenon that the materials in ball grinding mill are over grinded is avoided.
