In cold grinding, the materials to be ground are cooled and embrittled with cryogenic liquid nitrogen or carbon dioxide. Beim Kaltmahlen werden die zu mahlenden Materialien mit tiefkaltem, flüssigem Stickstoff oder Kohlendioxid gekühlt und versprödet. Cryogenic Separation A project where we acted as consultants, was the comparison of cryogenic separation with other forms of hazardous waste management technologies for the treatment of surface coatings and adhesives. Cryogenic separation is the separation of materials at a temperature that is below the freezing point of both materials.

Cryogenic grinding services since 1978 for plastics and other materials from R&D lab samples to large production volumes. Services include cryogenic granulation or chopping, cryogenic pulverizing or fine grinding, cryogenic sifting or screening. 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 to prevent melting. Sifting - Classifying Materials are usually sifted in line with grinding to control the upper or lower limit of the specified particle size.

OGL engineers use liquid nitrogen to both chill materials before grinding, and to maintain ultra-low temperatures while the mill is in operation. Chilling raw materials to cryogenic temperatures embrittles them, which means they fracture rather than bend, melt, or otherwise deform during milling. Powerful impact ball milling results in a perfect grinding efficiency. The Autofill system avoids direct contact with LN 2 and makes cryogenic grinding very safe. Its versatility (cryogenic, wet and dry grinding at room temperature) makes the CryoMill the ideal grinder for quantities up to 20 ml.

1) Cryogenic Grinding is the process of cooling or chilling materials and reducing it to small sized particles. Since almost all material embrittle when exposed to cold temperature. Cryogenic size reduction utilizes the cold energy available from defined cryogenic fluids to cool, embrittle and Cryo-milling can be used for: Reducing the material temperature below its glass transition temperature (T g), which is the point at which a polymer goes from a brittle, glassy state (low temperature) to an elastic, rubbery state (higher temperature). Materials below their T g are generally friable to some degree.
