摘要： PURPOSE:To obtain a ceramic raw material having excellent characteristics in terms of both quality and safety without admixture of impurities and requiring a binder for granulation by grinding a calcined ceramic raw material by using a specific pulverizer. CONSTITUTION:A calcined ceramic powdery or granular raw material is pressed against the inner peripheral face of a high-speed rotating casing 4 by centrifugal force. The raw material is strongly ground down by relatively revolving grinding pieces 9a on the raw material layer wherein movement of the raw material is limited by centrifugal force. The raw material layer is stirred and blended by raking pieces 9b relatively rotating on the raw material layer so that the pulverized raw material is sufficiently mixed and dispersed. Consequently, pulverization, uniform stirring and blending of the raw material are efficiently carried out in a short time as a whole.

摘要： PURPOSE:To store particulate matter of starting materials for a superconductor for over a long time while inhibiting deterioration of the quality due to atmospheric oxygen or moisture by covering the particulate matter with a covering material. CONSTITUTION:After calcining a primarily pulverized mixture of particulate starting materials for a superconductor, the product is sintered after secondary pulverization and mixing, to obtain thus a particulate matter of the superconducting material contg. Y or Bi. Then, the particulate matter is fed together with a covering material (e.g. fluoroplastic) to a treating chamber 3 of a bottomed cylindrical casing 4 revolved at high speed from a feeder 19 through a passage 6 with a transporting gas supplied by a fan 18. Thus, the particulate matter is covered by the covering material and pressed by a centrifugal force to an internal peripheral surface of the casing. Then, the particulate matter is pulverized by grinding pieces 9a by rotating the grinding pieces and scraping pieces 9b relatively with a fixed relative velocity difference against the casing 4 around a rotary shaft 8a interlocked to a driving device 5. The pulverized product is mixed simultaneously by stirring with the scraping pieces 9b, then conveyed pneumatically to a collector 15 from an overflow type discharging port 11 through a passage 10, and recovered.
