摘要
采用振动磨对分析纯碳酸钙粉末进行超细粉碎,获取超细碳酸钙。研究了粉碎时间、研磨介质大小、振动磨填充率对粉碎效果的影响,获得了最佳工艺条件。研究结果表明,采用振动磨能将原料碳酸钙粉碎到1.5μm左右的大小,随着粉碎时间的增加,粉体粒度尺寸逐渐减小,但减小到一定程度后,则基本保持不变甚至出现逆研磨现象。最佳工艺条件为10mm直径的研磨球、65%的填充率、500g的粉体质量的参数组合。
To obtain the minimum particle size calcium carbonate, the vibrated mill was used to grind analytically pure calcium carbonate. Parameters that grinding time, grinding media size and filling rate were studied in detail to select the optimal operation condition. The results showed that the vibrated mill could grind analytically pure calcium carbonate with size of about 1.5 tzm, and with the grinding time increased, the size of the particles decreased. However, its size remained even reversed when decreased to a certain degree. The best process condition is the parameter combination that 10 mm diameter grinding ball, 65% filling rate and 500 g powder quality.
