氧化鋁耐磨球是采用科學(xué)配方及先進(jìn)工藝制成，具有高密度、高硬度、高耐磨等特性。可減少研磨時間、增大粉碎空間、不污染被研物等優(yōu)點(diǎn)，但是其內(nèi)部也會有聚合物，要及時清理。
先將原始廢活性氧化鋁球經(jīng)清水清洗，烘干置于容器中。用稀硝酸或稀鹽酸溶液將廢活性氧化鋁球浸漬５～２５分鐘；將浸漬后的廢活性氧化鋁球經(jīng)水清洗和烘干，氧化鋁球表面污垢基本去除；
把氧化鋁球放入密閉的真空容器中，氧化鋁中的水分受壓強(qiáng)作用被汽化排出氧化鋁球表面小孔；在２００℃～３８０℃高溫加熱６～８ｈ，氧化鋁小孔內(nèi)表面的油脂被汽化、分解和碳化；對加溫后的氧化鋁進(jìn)行振動篩分，將小孔中的粉狀垃圾逐漸抖振篩分，脫離氧化鋁球小孔的內(nèi)表面。（圖/文www.xahjbz.com）

Alumina ball is the scientific formula and advanced technology, has a high density, high hardness, high wear resistance and other properties. Can reduce the grinding time, grinding, no pollution is increasing space research material advantages, but its interior also will have a polymer, in time to clean up.
The alumina ball into the sealed vacuum container, the water in alumina by pressure effect is vaporized from the hole on the surface of alumina ball; at 200～ 380 ℃high temperature 6 ～ 8h, alumina pores surface oils is vaporized, decomposition and carbonization; for heating the alumina in vibration screening, the small holes in the powdery wastes gradually buffeting screening, out of holes in the inner surface of alumina ball.
