2020-8-21 Ball milling is a simple and effective processing technique that induces structural, morphological and microstructural modification of materials by energetic impacts (balls to balls and balls to wall). Moreover, this technique can induce chemical reactions that do not normally occur at room temperature [ 1 ].

2020-6-15 The time of ball milling directly affects the particle size and purity of the product. During ball milling, due to the severe collision and friction of ball milling beads, part of the product will fall off. The longer of ball milling time, the more serious the pollution of the product will be.
2017-4-20 Ball milling (BM) is a well-established technique for producing different materials in powder shape. Dynamical analysis of BM helps to optimize the process through simple but general relations (e.g., definition of an equivalent milling time).
2017-1-15 Ball-milling is beneficial for the dispersion of GNSs in the copper matrix, however, long-time ball-milling can cause serious damage to the GNSs. When the GNSs content is small, the interfacial bonding between GNSs and copper matrix is good and GNSs are distributed along the boundary of
The effect of ball milling times, milling speeds, and composition on the structure and properties of NMC cathodes was determined. X-ray diffraction analysis showed that ball milling decreased primary particle (crystallite) size by up to 29%, and the crystallite size was correlated with the milling time and milling
