迄今为止,我国选矿界对磨矿介质研究最多的仍然是球介质。在生产中,选择球径的计算仍以简化了的K·A·拉苏莫夫公式为依据,即:至于F·C·榜德公式、B·A·奥列夫斯基公式,由于受到条件的限制,大多局限于试验室的范围内应用。尽管拉氏公式之后创立的计算球径公式林立,所考虑的影响因素增多,从理论上分析越来越全面。但是大多数实践者都清楚,企图用一个公式把所有影响球径的因素都包括进去,或者指望一个公式,立即就可以得出生产中用球准确无误的球径是不可能的。因此,考虑了入磨粒度、矿粒性质的拉氏公式就有其优越之处,不过在应用中人们又先后发现,根据简化了的拉氏公式计算得出的球径,对中硬矿石、特别 So far, most of the research on the grinding media in our country’s dressing industry is still the ball media. In production, the calculation of the choice of ball diameter is still based on the simplified K.A. Rasumov formula, namely: As for the F · C · Bachelor formula, the B · A · O · Levski formula, due to Conditions are mostly limited to laboratory applications. Although the formulas for calculating the diameter of a sphere created after the Laplace formula are numerous, the influencing factors to be considered are increasing, and the theoretical analysis is more and more comprehensive. But most practitioners know it’s impossible to include a formula that takes all the factors that affect the ball’s diameter into account, or if you expect a formula that immediately leads to an accurate ball diameter in production. Therefore, considering the grinding particle size, mineral properties of the Laguernes formula has its advantages, but in the application of people have also found that according to a simplified Laplace formula calculated by the diameter of the hard ore, especially
