Abstract The paper initially focusses on developing a test procedure for measuring the wear of grinding balls and then correlating the results with the wear obtained in industrial scale cement ball milling applications. The cost of grinding media is one of the major items and it needs to be optimized by testing different types of media. Since industrial scale trials are time consuming, there is a need for an easy, accurate and fast media wear testing procedure for cement ball milling applications. Such a procedure enables cement plants to compare wear results of different types of media and choose the optimal one for the economy of the grinding operation. Within the scope of the study, 6 types of 30 mm media having different chemical compositions were subjected to wear measurements at different time intervals by utilizing laboratory scale ball mills. The studies showed that reproducible results can be obtained from the test apparatus hence the methodology is said to be consistent. The wear results concluded that the order of the media wear from the highest to the lowest was the same independent of the mill dimension and whether the material is inside the mill. The results also implied that the chemical composition or the microstructure of the media was an influencing parameter on the wear therefore there is room for improvement with regards to the quality of media. This study proved that the media wear measured at industrial scale cement ball mills was in good agreement with the laboratory scale results.

开发用于水泥球磨应用的初步介质磨损测量测试程序

摘要 本文最初侧重于开发测量磨球磨损的测试程序,然后将结果与工业规模水泥球磨应用中获得的磨损相关联。研磨介质的成本是主要项目之一,需要通过测试不同类型的介质来优化。由于工业规模试验非常耗时,因此需要一种用于水泥球磨应用的简单、准确和快速的介质磨损测试程序。这种程序使水泥厂能够比较不同类型介质的磨损结果,并选择最经济的研磨操作。在研究范围内,使用实验室规模的球磨机在不同的时间间隔对 6 种具有不同化学成分的 30 毫米介质进行磨损测量。研究表明,可以从测试设备中获得可重复的结果,因此该方法被认为是一致的。磨损结果得出结论,介质磨损从高到低的顺序是相同的,与磨机尺寸和材料是否在磨机内无关。结果还表明,介质的化学成分或微观结构是影响磨损的参数,因此在介质质量方面还有改进的余地。该研究证明,在工业规模的水泥球磨机上测量的介质磨损与实验室规模的结果非常吻合。研究表明,可以从测试设备中获得可重复的结果,因此该方法被认为是一致的。磨损结果得出结论,介质磨损从高到低的顺序是相同的,与磨机尺寸和材料是否在磨机内无关。结果还表明,介质的化学成分或微观结构是影响磨损的参数,因此在介质质量方面还有改进的余地。该研究证明,在工业规模的水泥球磨机上测量的介质磨损与实验室规模的结果非常吻合。研究表明,可以从测试设备中获得可重复的结果,因此该方法被认为是一致的。磨损结果得出结论,介质磨损从高到低的顺序是相同的,与磨机尺寸和材料是否在磨机内无关。结果还表明,介质的化学成分或微观结构是影响磨损的参数,因此在介质质量方面还有改进的余地。该研究证明,在工业规模的水泥球磨机上测量的介质磨损与实验室规模的结果非常吻合。磨损结果得出结论,介质磨损从高到低的顺序是相同的,与磨机尺寸和材料是否在磨机内无关。结果还表明,介质的化学成分或微观结构是影响磨损的参数,因此在介质质量方面还有改进的余地。该研究证明,在工业规模的水泥球磨机上测量的介质磨损与实验室规模的结果非常吻合。磨损结果得出结论,介质磨损从高到低的顺序是相同的,与磨机尺寸和材料是否在磨机内无关。结果还表明,介质的化学成分或微观结构是影响磨损的参数,因此在介质质量方面还有改进的余地。这项研究证明,在工业规模的水泥球磨机上测量的介质磨损与实验室规模的结果非常吻合。
