Dutch started building windmills as early as 1,200 AD. to use them grinding grains. In the 19th century, there were more than 9,000 windmills in the Netherland. However, there are only around 1,200 still exist nowadays since fewer and fewer windmills are being used and maintained. In the past, ancient people build windmills to take advantage of ...

Cryogenic grinding, also known as freezer milling, freezer grinding, and cryomilling, is the act of cooling or chilling a material and then reducing it into a small particle size. For example, thermoplastics are difficult to grind to small particle sizes at ambient temperatures because they soften, adhere in lumpy masses and clog screens.

When changing from cryogenic down milling (Fig. 5a) to cryogenic up milling (Fig. 6a), higher forces are generally observed with the exception of two parameter combinations (f z = mm, v c = 50 m/min/f z = mm, v c = 100 m/min). Due to its kinematic, up milling does promote a higher amount of plastic deformation in the workpiece surface ...
