Grinding Rate of a Ball Mill Operated under Centrifugal Force [Translated]†

概要

論文の詳細を見る
Measurements of specific surface area of product were made on a new type of ball mill operated under centrifugal force. The results indicated that this type of mill was superior in grinding performance to the conventional ball mill operated under gravitational force and that the use of centrifugal force was effective in reducing the grinding time. An empirical equation was proposed for expressing the increase of specific surface area of product by the introduction of a non-dimensional parameter to evaluate the effect of centrifugal force. This equation was found to express well the grinding process under gravitational force as well as that under centrifugal force.† This report was originally printed in KAGAKU KOGAKU RONBUNSHU, 11(3), 311-316 (1985) in Japanese, before being translated into English by KONA Editorial Committee with the permission of the editorial committee of the Soc.
