A planetary ball milling machine (PM100, Retsch, Germany) was used for the grinding process, with milling speeds varying from 100 to 500 rpm and a milling time of 2 h. After ball milling, the obtained suspension was filtered through a 45 μm (325mesh) sieve, and the resulting powder was denoted to as +45 μm.

In Conclusion. While they both involve the physical removal of material from a workpiece, milling and grinding aren't the same. The former machining process is characterized by the use of a milling machine, whereas the latter machining process is characterized by the use of a grinding wheel. No tags for this post.
