<P>PROBLEM TO BE SOLVED: To solve the problem wherein moldings produced are uneven in density due to the irregularity in shape and a large particle size dispersion of a mixed powder, and a large number of voids are formed and the dimensional accuracy has been low when the moldings are sintered. <P>SOLUTION: The manufacturing apparatus for ceramic includes a supply opening 4b for supplying a mixture M of a ceramic raw material and a binder, also a first grinding member 4 having a grinding surface for grinding the mixture M in its outer peripheral part, and a second grinding member 5 being provided under the first grinding member 4 and having a grinding surface opposed to the grinding surface of the first grinding member 4 in the outer peripheral part while having a space to it; and at least one of the first grinding member 4 and the second grinding member 5 is constituted so as to be rotatable to the opposed grinding surface, and the mixture M is moved into the space between the grinding surface of the first grinding member 4 and the grinding surface of the second grinding member 5 by the rotating action of al least one of the first grinding member 4 and the second grinding member 5, and the mixture M is ground and granulated between the grinding surfaces. <P>COPYRIGHT: (C)2008,JPO&INPIT |
