The utility model provides a crushing device for recycled plastic materials. Recycled materials pass through a feeding port, a first crushing component, a second crushing chamber, an internal discharge port, a third grinding component and an external discharge port in sequence. The first crushing component comprises a first rotor and a second rotor rotating in opposite directions. The second crushing chamber consists of a centrifugal rotating cylinder and rigid baffles. The centrifugal rotating cylinder is a cylindrical structure with a sealing cover at one top end and an internal feeding port on the cover. Crushed raw materials enter the cylinder through the internal feeding port, and internal discharge ports are arranged on the cylinder wall with an outlet direction forming an included angle of 30‑40° upward with the vertical central axis of the centrifugal rotating cylinder.
