The extent of bran layer removal during the milling process is referred to as the degree of milling (DOM) or processing precision (Gujral et al., 2002). The appearance and cooking quality of the rice, as well as its palatability, improve with increasing DOM, while the phenol, mineral, dietary fiber, antioxidant activity, and γoryzanol ...

The optimization of the operating parameters of a stirred media mill in the dry grinding of calcite was investigated. A threelevel BoxBehnken design was used for the purpose of examining the impact of four independent factors, the stirrer speed (SS), grinding time (GT), media filling ratio (MFR), and solid mass fraction (SMF), on the product particle size (d50).

Face milling is a process used to cut material from the top face of a workpiece. Face milling is done using a milling machine or a machine center, and uses an end mill, fly cutters, or shell mill tools. All of these tools achieve a similar result, which is to remove material from the top surface of a workpiece.
