Cryogenic grinders generally consist of precoolers and grinder with the cryogen distribution system. In such grinding systems, cryogens subject the raw 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 Grinders At Rs 2500000units Cryogenic . Cryogenic grinding is a process of mixing liquid nitrogen with a spice to lower the temperature up to -190 degrees c, then grinding the super-cooled product.This type of grinding system protects spices essential oils and other vital constituents that could be lost during conventional grinding.Features minimal loss of volatile components.
In order to grind tough and elastic materials with a high throughput into fine powder, an efficient cryogenic cold grinding system is required. The feed material must firstly be cooled with a suitable refrigerant such as e.g. liquid nitrogen to a defined temperature usually below the glass transition or softening temperature to cool.

Particle size reduction, or grinding, is a process to produce a polymer powder necessary for a particular industry or technology. This can be accomplished by starting with resin pellets or a powder that is ground to a finer powder. At Ancos, we can achieve a range of desired size distributions to meet specifications, from coarse to fine.

Theoreti- cally, a tyre crushing operation should use only 0.42 Mg LIN/Mg scrap and in some instances LIN consumptions as low as 0.6 Mg/Mg scrap have been re- ported but in other cases a double ...
Cryogenic Treatment is unique in that it reduces the cost of racing and makes the car more competitive at the same time due to the increases in component life. Racers have reported lifespan increases of 500% on valve springs. They report 300% increase on racing engines, 300% on transmissions, in addition to 300% on brake rotors.

conventional cryogenic grinding we should be able to cut liquid nitrogen consumption by 20–40%. To cut costs even further, mechanical refrigeration can replace some or even all of the liquid nitrogen – and in the latter case that means total operating costs, including capital charges, of just 15–20% of the cost of an equivalent cryogenic mill.”

Deep cryogenic treatment of grinding wheels, whether you’re working with electroplated, super abrasive or vitreous-bonded wheels, has proven to be incredibly effective.On average, treated wheels stay sharper longer with less need for dressing. Our process affects the crystal structure in the grinding grain, which enhance wheel durability and lifespan.
The Autofill system avoids direct contact with LN2 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.
