In recent years, the medium aluminum balls, which have been used for neutralizing mud in the ball mill, have shown a trend of being replaced by medium and high alumina ceramic balls. The functions of the two ceramic balls are the same, and the medium and high aluminum balls are more and more recognized and welcomed by ceramic companies due to their comprehensive advantages.

　　 From the point of view of purchase cost, Chinalco Ball is 1,800 yuan/ton. Medium, medium and high aluminum balls are 3700 yuan per ton. The price of medium and high aluminum balls is more than twice as high as that of medium aluminum balls. However, the hourly wear rate of the aluminum balls is three ten thousandths, and the hourly wear rate of the medium-high aluminum balls is one ten thousandths. The service life of medium and high aluminum balls is three times longer than that of medium aluminum balls. Therefore, the substantial cost of medium and high aluminum balls is not higher than that of Chinese aluminum balls, but the manufacturers cannot afford to pay more for medium and high aluminum balls when purchasing. Secondly, the ball mill is a big power consuming machine. It takes 11 hours to work for a grinding material using medium aluminum balls, while it only needs 9 hours to use medium and high aluminum balls. Each time the medium and high aluminum balls are ground, it can save electricity for 2 hours and 400 kWh compared with the medium aluminum balls. The daily output of a roller kiln requires 2 ball mills to make powder to ensure the output. Therefore, a line a day can save 800 degrees of electricity due to the use of medium and high aluminum balls, and the tax of the ceramic tile factory is calculated based on the electricity consumption. Therefore, as the power consumption of the ceramic tile factory is reduced, the tax is also reduced, and the production cost is significantly reduced. In addition, replacing the medium aluminum balls with medium and high aluminum balls can reduce the installed ceramic balls by half. A ball mill must use 78 tons of medium aluminum balls, while the use of medium and high aluminum balls only costs 66 tons. Therefore, the use of medium and high aluminum ball mills has With more space, these spaces have been replaced by mud. The operation of the ball mill has increased the output by more than ten percent without increasing the cost, and the cost has also been reduced accordingly.

　　 Nowadays, more and more ceramic tile companies that are sensitive to production costs are switching to medium and high aluminum balls. However, due to the shortage of funds, some ceramic tile companies are not buying medium and high aluminum balls for gold. And once the procurement channels are changed, they will be chased by the old suppliers. Therefore, in the short term, it is still difficult for some manufacturers to abandon the aluminum balls and switch to medium and high aluminum balls.
