<p><P>PROBLEM TO BE SOLVED: To provide a grinding device which can obtain a high efficiency of removing cement mortar by filling only concrete masses. <P>SOLUTION: A discharge amount regulation plate 7 for regulating the lower part of an annular grinding chamber 6 is attached to a cylindrical rotor 4 to always vibrate the regulation plate 7 by the eccentric rotation of the cylindrical rotor 4. A weir 7a is installed along the outer peripheral edge of the regulation plate 7 so that the top of the weir 7 is positioned outside of a conical surface 7b extended from the bottom inner periphery of a vertical cylindrical member 2 to make a repose angleϕ. Thereby, even when the regulation plate 7 approaches the bottom of the grinding chamber 6, a space between the bottom of the grinding chamber 6 and the regulation plate 7 is not closed, and the discharge port at the bottom of the grinding chamber 6 is always occluded by the concrete masses, which can ensure a sufficient residence time required for grinding to improve the efficiency of removing the cement mortar by filling only the concrete masses. <P>COPYRIGHT: (C)2004,JPO</p> |
