A machine learning approach for ball milling of alumina
In this work, machine learning approach based on polynomial regression was explored to analyze the optimal processing parameters and predict the target particle sizes for ball milling of alumina ceramics. Data points were experimentally collected by measuring the particle sizes. Prediction interval (PI)-based optimization methods using milling machines are broadly classified into various types: Vertical Axis ball milling machines, Horizontal axis ball milling machines, Industrial ball milling machines, Planetary (Multi-jar) ball milling machines. The ball milling machine used in this research is a special type of ball milling machine which is designed as a combination of aVWRUDJHGHYLFHV IOPscience

Use of Taguchi method for high energy ball milling of CaCO3
Taguchi’s method was applied to investigate the effect of main high energy ball milling (HEBM) parameters: milling time (MT), ball to powder weight ratio (BPWR), and milling speed (MS) on the CaCO3 crystallite size. The settings of HEBM parameters were determined by using the L9 (33) orthogonal experiments array (OA). The as-received and A fuzzy controller was designed for the control flow rate inside the ball mill to avoid overfilling or emptying the mill [34]. The fuzzy system was used to optimize the ball milling circuit [35Process flow diagram of the primary ROM ball milling circuit
