Cryogenic grinding is used for grinding spices, thermoplastics, Elastomers, color concentrates, and similar materials. It is also used to recover a variety of scrap materials, such as factory scrap rubber and scrap tires, and to separate the components in composite materials.

Cryogenic grinding usually starts with chips or a fine crumb. This is cooled using a chiller. The final product is a range of particle sizes which are sorted and either used as is or passed on and further size reduction performed .The cryogenic process produces fairly

Cryogenic grinding is used for grinding spices, thermoplastics, elastomers, color concentrates, and similar materials. It is also used to recover a variety of scrap materials, such as factory scrap rubber and scrap tires, and to separate the components in composite materials.

Cryogenic grinding is necessary for materials with a low melting point or those that are very tough and difficult to grind fine without extra cooling. Fine grinding/pulverization/cryogenic grinding is available for 8 - 200 mesh or 2000 - 75 microns and finer for friable materials. Call. View Supplier. Save.

Many components such as circuit boards, wire, solder, polymers and resins are difficult if not impossible to grind using traditional methods. Cryogenic grinding in the SPEX . SamplePrep Freezer/Mill® is the easiest way to homogenize these materials. Using cryogenic grinding to chill samples until they are brittle, and then break them up through
