The pebbles used to be ball milled and glazed by daily ceramic factories and architectural ceramic factories, which have been washed away by seawater for a long time. But currently, there are not many of these materials available, and the wear is high, making it difficult to control the grading of the grinding balls. They are no longer suitable for the requirements of modern high-quality and ball milling processes, and are gradually being replaced by manually manufactured ceramic balls. However, a certain density of grinding balls needs to be prepared. According to the general manufacturing method, multiple tests and adjustments such as formula testing and density measurement are required to achieve this, which is too long, time-consuming, laborious, and wasteful of materials. Through research and exploration, we have found that the true density of each raw material composed of ceramic balls can be calculated in advance using the addition method and different coefficients according to different molding methods. If the density is the same as the required density, adjustments can be made through calculation until the required density is basically consistent with the density measured through experimental manufacturing. Moreover, this method can also control costs.
