A first motor and a second motor are arranged on both sides of the feed inlet. A shaft is installed on one side of each motor, and a plurality of crushing teeth are arranged on the shaft. The crushing teeth on the two shafts are arranged alternately. The raw materials are placed in the feed inlet, and the motor drives the shaft to rotate, so that the crushing teeth further crush the raw materials, making them more delicate. The crushed raw materials fall on the screening plate through the grid plate. The vibrator on both sides of the screening plate makes the screening plate vibrate for screening. The screening plate is provided with three layers for multiple screening. The problem of general recycled concrete screening devices that cannot screen the concrete particles completely and require multiple screening, reducing the work efficiency, is solved.
