High-strength impact-resistant gradient material ceramic grinding ball and preparation method thereof
The invention relates to a high-strength impact-resistant gradient material ceramic grinding ball material which comprises N material layers, and N is larger than or equal to 4. And in each material layer, the aluminum oxide accounts for 35wt%-95wt% by mass, and the balance is the composite auxiliary material. The method has the beneficial effects that powder materials of different layers can reach the optimal sintering temperature area, so that sintering is compact, layer interface defects are few, the specific gravity range of the multi-gradient material grinding balls is wide, and the requirement range of the grinding balls of a high-energy-density ore grinding method is basically covered; the overall toughness, strength and impact resistance of the material can be greatly improved; the method is low in production cost and suitable for industrial batch production; compared with a common grinding ball, the grinding ball has the advantages that the situation that abrasion is obviously aggravated due to peeling, notches, ball breaking and the like in severe working conditions can be avoided, the consumption of the grinding ball used in novel efficient energy-saving technologies such as semi-autogenous grinding of a large mine is greatly reduced, and the grinding ball has very obvious economic benefits.
本发明涉及一种高强度抗冲击梯度材料陶瓷研磨球材料，包括：N层材料层，N≥4；每层材料层中，以质量百分比计，氧化铝占35wt％～95wt％，其余为复合辅助材料。本发明的有益效果是：将不同层的粉体物料均能达到最佳烧结温度区域从而烧结致密，层界面缺陷少，且多梯度材料研磨球的比重范围宽，基本覆盖高能量密度磨矿方法的研磨球需求范围；能够极大提高材料的整体韧性、强度以及抗冲击能力；生产成本低，适用于工业化批量生产；相较于普通研磨球，能够避免在恶劣工况中出现剥皮、缺口、碎球等明显加剧磨耗的情况，大大降低了大型矿山半自磨等新型高效节能技术中使用的研磨球消耗量，具有非常明显的经济效益。
