5升立式批次搅拌球磨机是用来研究给料铬铁矿砂的破碎特征。对搅拌球磨机磨矿有影响的因子设计参数如下：矿浆浓度、销端线速度、球密度和球尺寸，在搅拌球磨机磨铬铁矿砂所需的能量由使用查尔斯（Charles）方程来确定。研究结果与这个方程取得的结果是一致的，这显示出罗森—来姆勒（Rosin－Rammler）粒级分布方程取得的数据适合于较宽范围的操作条件。由于罗森—来姆勒（Rosin－Rammler）线是平行的，因此，在任何特殊磨矿条件下可能仅仅使用粒级系数运算。论证了选择函数和查尔斯（Charles）能量一粒级之间的关系，也讨论了与邦德（Bond）定律的联系，并总结出邦德（Bond）定律不适合在这种磨矿方式下应用。对磨矿能力有最大影响因素按重要性顺序是：球尺寸、销端线速度和球密度。磨矿参数之间的相互作用可忽略不计。这个结果可以精确预测所要求的产品规格所需要的磨矿条件。
A 5-liter vertical batch stirred ball mill was used to study the crushing characteristics of the feed chromite. Factors affecting the mill mill grinding design parameters are as follows: slurry concentration, pin end line speed, ball density and ball size. The energy required to grind chromite in a stirred mill is determined using the Charles equation. The results are in agreement with the results obtained from this equation, which shows that the data obtained by the Rosin-Rammler particle size distribution equation are suitable for a wide range of operating conditions. Since the Rosin-Rammler lines are parallel, it is possible to use only fractional factoring in any particular grinding condition. The relationship between the selection function and the Charles energy level is demonstrated. The bond with Bond’s law is also discussed and the Bond law is not fit for use in this type of grinding . The order of importance of the factors that have the greatest influence on grinding capacity is the ball size, pin speed and ball density. The interaction between grinding parameters is negligible. This result accurately predicts the grinding conditions required for the required product specifications.
