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.

In SAG mill operation, the grinding rate passes through a minimum at a "critical size" ( Chapter 5 ), which represents material too large to be broken by the steel grinding …
Ball mills are among the most variable and effective tools when it comes to size reduction of hard, brittle or fibrous materials. The variety of grinding modes, usable volumes and available grinding tool materials make ball mills the perfect match for a vast range of applications. Cooling, heating & cryogenic grinding.
Unlike other grinding mills, AG mills do not typically use additional grinding media such as steel balls or rods. Charge: The material inside the AG mill, consisting of the ore itself, is referred to as the "charge." The grinding action takes place as the cylinder rotates, causing the ore to cascade and tumble within the mill. ...
Planetary Ball Mills 101 from Union Process Inc. Planetary ball mills share the same design as other basic ball mills – a grinding jar filled with media and rotated on its own axis.
