氧化铝耐磨球是采用科学配方及先进工艺制成，具有高密度、高硬度、高耐磨等特性。可减少研磨时间、增大粉碎空间、不污染被研物等优点，但是其内部也会有聚合物，要及时清理。
先将原始废活性氧化铝球经清水清洗，烘干置于容器中。用稀硝酸或稀盐酸溶液将废活性氧化铝球浸渍５～２５分钟；将浸渍后的废活性氧化铝球经水清洗和烘干，氧化铝球表面污垢基本去除；
把氧化铝球放入密闭的真空容器中，氧化铝中的水分受压强作用被汽化排出氧化铝球表面小孔；在２００℃～３８０℃高温加热６～８ｈ，氧化铝小孔内表面的油脂被汽化、分解和碳化；对加温后的氧化铝进行振动筛分，将小孔中的粉状垃圾逐渐抖振筛分，脱离氧化铝球小孔的内表面。（图/文www.yxwdcy.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.
