Cryogenic grinding Wikipedia
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 chilled by dry ice, liquid carbon dioxide or liquid

Milling Vs Grinding Custom Milling & Consulting
Breaking down and reducing particles in a liquid medium or slurry is referred to by two different terms, milling or grinding. There is a minimal difference between the two terms and it depends on what area of the world you are located in or what industry you are working in. Both are used to describe the process of taking particles and decreasing them down to micro and nanometer sizes. Milling
