OGL engineers use liquid nitrogen to both chill materials before grinding, and to maintain ultra-low temperatures while the mill is in operation. Chilling materials to cryogenic temperatures embrittles them, which means they fracture rather than bend, melt, or otherwise deform during milling.
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 impact, crushing, or shearing allows the toughest samples to be ground.

SPEX Europe‘s Freezer/Mill is a programmable cryogenic mill specifically designed for grinding and pulverizing tough or temperature sensitive samples.. This technique makes a difference especially for soft, sticky, tough, lubri ing and fibrous samples or for samples whose composition or structure changes due to the heat generated by conventional grinding.
Cryogenic grinding of thermoplastics and elastomers. Process Description. In cold grinding, the materials to be ground are cooled and embrittled with cryogenic liquid nitrogen or carbon dioxide. This method achieves particularly high grain fineness while maintaining product quality. In addition, the mill throughput is significantly increased.
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,” said Burmester. Air Products is supporting the project along with several manufacturers of grinding equipment, and are usually in the form of liquid gases and canBurmester has been closely involved. liquid nitrogen LN2 , oxygen, helium LHe , methane, Notable features, he says, are the use of
The term “CRYOGENICS” originates from Greek word which means creation or production by means of cold. Cryogenics is the study of very low temperature or the production of the same, Liquid nitrogen is the most commonly used element in Cryogenics and is legally purchasable around the world. Cryogenic Grinding technology can efficiently

Cryogenic grinders generally consist of precoolers and grinder with the cryogen distribution system. In such grinding systems, cryogens subject the material up to or lower than glass transition temperature before it is ground, thus eliminating much of the material and quality hassles of traditional grinding.
Cryogenic grinding of flexible materials. Contact our engineer to cut, require a large amount of energy, and after some time clog the device preventing it from working effectively. Grinding a charge to particles of a few millimeters is an extremely difficult challenge, and pulverizing to particles of a micrometer size can practically be
Cryogenic Grinding is also known as cryo- milling is a process of cooling a material to a low temperature and then reducing the dimensions of the material. Once cooling is completed, the material becomes em-brittle i.e. the material loses its ductility. The cryogenic Grinding process involves two units i.e. precooling unit and grinding unit.
Cryogenic grinding is used for easily meltable, flexible, ductile and fibrous products where very high fineness of up to 30 µm is required traditional methods for these products do not achieve fineness values below 300-500 µm . Cryogenic grinding can be used in a safe manner for products posing an explosion risk.
With the cryogenic grinding technique, the waste of an unknown material may be completely minimized with the fluid nitrogen or liquid carbon dioxide, which gives pre-cooling the organism and preserves the optimal temperature range by rising the heat generated while mixing.
The cryogenic grinding lowers the thermal related problems Reduced grinding forces High M.R.R. can be achieved Minimizing residual stress and micro-cracks Retention of wheel grit sharpness i.e. low rate of grit wear Surface finish, dimensional accuracy and tool life improved Difficult-to-machine materials can also be machined Moreover, use of
