Aggregate recycling and crushing device for high-impermeability recycled concrete

The invention relates to an aggregate recycling and crushing device for high-impermeability recycled concrete, and belongs to the technical field of concrete waste recycling. The aggregate recycling and crushing device comprises a machine body, a feeding opening is formed in the top of the machine body, a crushing device is arranged in the machine body, and a guide plate is arranged below the crushing device and is obliquely arranged; a magnetic roller is arranged between the guide plate and the crushing device and has magnetism, a first motor used for driving the magnetic roller to rotate is installed at one end of the magnetic roller, a metal guide plate is arranged on one side of the magnetic roller in the downward inclined direction, and one end of the metal guide plate abuts against the side wall of the magnetic roller. And the other end of the metal guide plate penetrates through the side wall of the machine body and extends out of the machine body from the interior of the machine body. The application
