In ball milling of dry solids the main independent variables are mill diameter, mill speed, media size, solids loading and residence time. For most companies the production mill already exists so we can ignore mill diameter and focus on the other variables.

2021-2-19 The ball mill process parameters discussed in this study are ball to powder weight ratio, ball mill working capacity and ball mill speed. As Taguchi array, also known as orthogonal array design, adds a new dimension to conventional experimental design, therefore, Orthogonal array (L9) was carefully chosen for experimental design to understand the effects of the ball mill process factors [ 16 ].

2017-5-28 Effect of process variables on the synthesis of MgB 2 by high energy ball mill 971 pressing. MA was performed in a planetary ball mill with using high quality amorphous B (99.9 wt %) and Mg (99.8 wt %) powders at the BPR of 36:1. The results confirmed that such powder consist of nanocrystalline grains and was very reactive for alloying.

2010-2-20 Factorial design enables analysis of process parameters as independent variables. This tool is especially efficient for complex systems with multiple variables and responses, such as ball mills. The statistical computation provides a quantitative overview of the process parameters on the basis of a restricted number of experiments.

2017-9-18 The process variables, such as chip thickness distribution and cutting speed distribution, can be simulated by means of discrete representation of the workpiece surface and the cutting tool. In the current approach, the workpiece surface is represented with a Z map. The cutting edge of the tool is represented by a set of nodes.
