PRODUCTION METHOD FOR A TRULY SPHERICAL CERAMIC BALL BY MEANS OF A ROTATIONAL METHOD, AND A DEVICE THEREFOR

摘要

The present invention relates to a production method for a truly spherical ceramic ball by means of a rotational method, and to a device therefor. More specifically, a method is disclosed which makes it easy to mould ceramic powders into a spherical shape by using seeds, and which on the other hand allows the production of ceramic balls which are strong and at the same time have an outstanding particle size distribution by repeatedly heating and cooling during the moulding process or making balls of similar size undergo the moulding process via an interim selection process. Also, a device for producing ceramic balls is provided which makes use of the rotational method.
