Get PriceCryogenic milling allows us to keep the volatile oils and moisture in our products, not on our machinery. Cryogenic grinding also allows products to be ground and crushed at a lower level of stress, depending on the hardness of each product, causing in lower energy output.
Get PriceOur grinding centers use liquid nitrogen produced by our OGL partner division and the very latest cryogenic freezing technology to lower the temperature of your materials to 320° F (196° C). This allows us to grind food or polymers that can't be ground at ambient temperatures, or which degrade in heat generated by conventional milling processes.
Get Price· Cryogenic grinding systems must be designed to operate at low temperatures approximately 100°F (73°C) or colder to successfully grind many thermoplastics and spices, especially those with high oil content. The grinding systems must be well insulated, especially where the liquid nitrogen contacts the material being processed.
Get PriceSince the early 1990s, cryogenic grind ing technology has been used by the waste recycling industry to produce rub ber crumb. The main advantage of this technology is that by cooling the material to cryogenic temperatures using liquid nitrogen (LIN), it becomes more brittle and can be broken up more easily into small particles using less energy.
