PRODUCTION METHOD FOR PULVERIZING MEDIA, AND PULVERIZING MEDIA
To provide a production method for pulverizing media such as balls or beads preventing breakdown during pulverization, improving the abrasion resistance thereof to prolong the service life thereof and used in a pulverizer such as a vibration mill or a sand mill.SOLUTION: A production method for a pulverizing media consisting of a ceramic sintered body including zirconia as a main component comprises: a drying process of drying a compact of a particle size D (mm) prepared by molding ceramic raw material powder including zirconia as the main component into a spherical type at a moisture decrement A (wt.%/h) based on 100 wt.% of the weight before drying; and a sintering process of sintering the compact went through the drying process. The above particle size D and the moisture decrement A satisfy the relation of D×A≤0.5D+1.SELECTED DRAWING: None
【課題】粉砕中における破壊を防止するとともに、耐摩耗性を向上し高寿命化した、振動ミル、サンドミル等の粉砕機に用いられるボール、ビーズ等の粉砕用メディアの製造方法の提供。【解決手段】ジルコニアを主成分とするセラミック焼結体からなる粉砕用メディアの製造方法であって：ジルコニアを主成分とするセラミック原料粉末を球状に成形した粒子径Ｄ（ｍｍ）の成形体を、乾燥前の重量を１００重量％として水分減少率Ａ（重量％／ｈ）で乾燥させる乾燥工程；前記乾燥工程を経た成形体を焼結する焼結工程；を有する粉砕用メディアの製造方法であって、前記粒子径Ｄと水分減少率ＡがＤ０．５×Ａ≦０．５Ｄ＋１の関係を満たす粉砕用メディアの製造方法。【選択図】なし
