ABSTRACT:
A booster8extending in an internal area53of a sieve7is attached to the outer circumferential face of a rotating shaft6. The booster8has four blades82, which are radially extended from the outer circumferential face of the rotating shaft6and are arranged at preset angles (for example, 90 degrees) to form a pi shape from the front view. The booster8has multiple (for example, two) cross-shaped radial members81that are arranged radially at a little angle (for example, 3 degrees) and are located on both ends of the rotating shaft6via a preset space, the blades82that are set in and fixed to the respective ends of each of the radial members81and are inclined at a preset angle to the axial direction of the rotating shaft6, and sheet-like scrapers83that are attached to the blades82to be a little projected outward in the radial direction. The end of each scraper83faces the inner circumferential face of the sieve7across a little gap. Each of the radial members 81 has a round opening81aon the center thereof to receive and fix the rotating shaft6passing therethrough.
