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.
the rubber or tire chip. The cooled rubber is ground in an impact type reduction unit, usually a hammer mill. This process can be used to produce fine micronized rubber powder ranging from 30 mesh size (595 microns) to 300 mesh size (50 microns). Micronized rubber produced by cryogenic process behaves like reinforcing filler in a rubber compound.
Hemant et al. A Review on Cryogenic Grinding 422| MITCOE, & DIAT, Pune, AMET-2017, IJCET INPRESSO Special Issue-7 (March 2017) preventing the possibility of fine-particle grinding. However, cryogenic gases prevent this by embrittling the material in a cooling conveying screw. The cryogenically ground plastic and the gas are collected
In order to produce high value fine rubber powder, the cryogenic grinding technology will lead to the recycling process of scrap tires in the future. 2. Cryogenic Grinding Technology of Waste Tire Cryogenic grinding is a process to comminute brittle materials (tires, rubber …

Jan 01, 2000· During the cryogenic grinding of scrap tire peels, the limit may increase sharply since they are much more thermally sensitive than other materials [7, 8]. That is to say that in the cryogenic grinding process, much finer rubber powders (e.g. below 50 µm) are impossible to attain. 194 S. B. Liang and H. Yunchen Figure 5.
Cryogenic Grinding System When using the system, measurable and repeatable results are obtained for lab or productions calculations. Mills range in size from 7-1/2 HP to 200 HP. With our cryogenic grinding unit an understanding develops with interaction of equipment components and operating parameters. Factors such as consistent feed rate, precise

Midwest Elastomers, Inc. is committed to the processing of high quality, finely ground plastics and rubber materials serving industrial and commercial markets that demand strict specifications. Some of our other core services include playground tiles, Flexithane, Cryogenic Grinding and Polypropylene powder.
Cryogenic grinding is often performed in impact mills and hammer mills, but the use of an internally agitated ball mill, like an Attritor, can provide additional benefits. Attritors can generally grind to finer size particle size range than impact or hammer mills by combining the advantages of cryogenic temperatures with both impact and shear ...
Cryogenic Fine Grinding of Rubber from Used Tires Superfine powdered rubber can be manufactured efficiently using a cryogenic process. Liquid nitrogen is employed to cool the feed granules below their glass transition temperature before they are pulverized with counter-rotating pin mills.
Cryogenic grinding can achieve a very fine level of grind as most hardy materials tend to become brittle when cooled with liquid nitrogen. To produce crumb rubber, it is necessary to reduce the size of the tire shred or chip. This is accomplished by techniques called cryogenic grinding. Cryogenic processing refers to the use of liquid nitrogen ...

OGL Cryogenic Grinding & Milling Services. Osaka Gas Liquid's Grinding & Milling Division uses liquid nitrogen critical for cryogenic grinding provided by our OGL partner division. OGL liquid nitrogen is delivered to our state-of-the-art grinding centers, which are specialized for either food or polymer grinding.
Jan 01, 1981· Developments in cryogenic grinding of rubber The principle cryogenic size reduction. Rubber is tough at 25 and so the size :eeiuction of scrap rubber at ambient temperatures has been hindered by large energy consumption and low throughput rates[1O].
Cryogenic Fine Grinding Technology for Rubber, Plastic and Pigment Size Reduction.Air Products has the capability to fine grind rubber for recycling or plastics and pigments to the finest grain by using liquid nitrogen to cool the material in a grinding mill.

Cryogenic processing refers to the use of liquid nitrogen to freeze tyre chips or rubber particles prior to size reduction. Most rubber becomes brittle or "glass-like" at temperatures below minus 80°C. This process can be used to produce fine micronized rubber powder ranging from 80 mesh size (177 microns) to 300 mesh size (50 microns).
