A multi-stage screening device for recycled aggregate

Abstract

The utility model relates to a screening device, especially a circulating multi-stage screening device for aggregate. The utility model wants to solve the technical problem to provide a circulating multi-stage screening device for aggregate which improves screening efficiency. The utility model provides a circulating multi-stage screening device for aggregate, which comprises a shell, a charging box, a feeding hopper, a screening mechanism and a vibrating assembly, the screening mechanism is fixedly connected inside the shell, a feeding hopper is fixedly connected to the screening mechanism, each of the left and right sides of the shell is provided with a material leakage hole, three charging boxes are sequentially and slidably connected from top to bottom in the bottom of the shell, and the three charging boxes are communicated with the material leakage holes. The utility model sequentially installs a plurality of screens with different aperture sizes on the vibrating frame, so that the aggregate can be screened once to pick out products with various specifications, thereby improving the screening efficiency.
