In this study, considering different operational parameters for stirred media mill, change in specific energy was compared to the change in R_x values, i.e. the cumulative weight of the material undersized to a specific sieve. R values, namely R₃₈, R₇₅, R₁₀₆, were measured before and after grinding in stirred mill. The change in R_x (ΔR_x, %) values were calculated and they were used to evaluate the certain unit of effectual energy (Ecb). This abovementioned calculation is performed by proportioning the Specific Energy (SE) to ΔR_x values. The effectual part of SE is considered to be the ratio of the energy needed only for size reduction in grinding and it should be related to the ΔR_x. The relative Ecb ratios of different grinding conditions give the relative specific energy efficiency ratio (SEe). The relative specific energy efficiency ratio is inversely proportional to specific grinding parameters and ground product particle sizes. The relative specific energy efficiency can be considered as the relative amount of energy for various grinding conditions. The variation between relative energy amount and the previously specified particle size provides a realistic comparison of different grinding parameters. The abovementioned variation could be employed to understand the resistance particle size which is a new concept to describe the particle size at which the maximum effectual SE is directly used. In the context of this study, it was aimed to figure out the interrelation between specific energy efficiency and PSD variation along with the resistance particle size.

在这项研究中，考虑到搅拌介质研磨机的不同操作参数，将比能的变化与R _x值的变化进行了比较，即相对于特定筛子筛分的物料的累计重量。在搅拌研磨机中研磨之前和之后测量R值，即R ₃₈，R ₇₅，R ₁₀₆。R中的变化_X（ΔR _X，％）值计算并且它们被用来评估有效的能量（E的某些单元CB）。此上述的计算是通过配比的比能（SE）到ΔR进行_X价值观。SE的有效的部分被认为是仅适用于磨削尺寸减小所需要的能量的比值，它应与在ΔR _X。不同研磨条件下的相对E cb比给出相对比能效比（SE e）。相对比能效比与特定磨削参数和研磨产品粒度成反比。相对比能量效率可以认为是各种研磨条件下的相对能量。相对能量和先前指定的粒度之间的变化提供了不同研磨参数的实际比较。可以采用上述变化来理解电阻粒径，这是描述直接使用最大有效SE的粒径的新概念。在这项研究的背景下，旨在找出比能效和PSD变化以及电阻粒径之间的相互关系。
