Abstract
In a continuous mixer, a chamber formed in a barrel comprising a feed port for feeding raw material to be mixed on one end side and a discharge port for discharging mixed material on the other end side. A pair of screw provided in the chamber has a feed part for conveying raw material to be mixed which is fed through the feed port and a mixing part for mixing the raw material. The barrel is provided with a raw material discharge port for communicating the position corresponding to the feed part in the chamber to the outside of the barrel, and an opening/closing cover for freely opening and closing the raw material discharge port. The screw can be rotated reversibly. Even though large amounts of raw materials to be mixed may stay in the chamber due to an emergency stop, the raw materials can be easily discharged from the raw material discharge port.
