Solids Choose the Right Grinding Mill · For attrition milling media size ranges from 1/8 in to 3/8 in with smaller media generally resulting in faster particle reduction — because for a given volume there ll be more impact and surface contact As media becomes smaller than 1/8 in mass is significantly reduced resulting in less impact force and thus longer grind times When ultrafine grinding isn t needed larger diameter
Cryogenic grinding WikipediaCryogenic 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 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
