Further, the volume of the left end portion of the main pressure chamber 21 having the passage opening 20 is substantially equal to the volume of the pre-pressure chamber 22, so that the waste can be pressed to 50% by the primary pressing of the pre-pressure hammer head 32, thereby achieving the optimal filling of the compression chamber 2 and improving the efficiency.
Further, the dry material discharge port is formed at the right end face of the main pressure chamber 21, and the door plate 52 and the main pressure ram 42 are arranged in a left-right opposite manner; that is, the door panel 52 is substantially perpendicular to the central axis X of the main pressure chamber 21.
