 — In the following, the theoretical background of cryogenic grinding and a new technology based on an alternative cooling equipment are presented. With the alternative technology, the operation costs during cold grinding will be drastically reduced. At the end, experimental results show effects of the variation of different running parameters.

Cryogenic grinding is an innovative process that involves grinding plastic materials at extremely low temperatures to prevent melting. By subjecting the plastic to sub-zero temperatures, typically using liquid nitrogen or carbon dioxide, the material becomes brittle and can be easily ground down into a fine powder.

 — Initial experiments (various cutting speeds 5−15 m/s, feed rates 1000−3000 mm/min, depth of cuts 5−50 μm and dressing overlap ratios 2 < U d < 8 and dressing speed ratios −0.9 < q d < +0.9) demonstrated cutting speed and dressing speed ratio had the most effect on the output parameter, due to significant influence on cutting temperature, so …

For over 30 years, we have been offering cryogenic and ambient grinding services to produce fine mesh powders and granules from rubber and plastic materials. The ISO 9000:2008 standards is an internationally recognized quality management system standard developed by the International Organization for Standardization (ISO).

 — Gradient ultra-fine-grained microstructures of pure copper were obtained via surficial cryogenic grinding. The microhardness increased gradually from 110 to 158 HV, corresponding to the nondeformed matrix and the surficial materials, respectively. Elongated and equiaxed ultrafine grains were observed. The modes of grain refinement …

Cold Grinding with the pin mill (Cryogenic Milling) Cryogenic Milling is a process to reduce particles by means of mechanical force as well as embrittlement of the material by means of cooling by liquid nitrogen. Thus, the fracture behaviour of viscous or elastic materials is transferred into the state that a grinding/ milling is possible.

In this review, as mentioned above, Section 2 and Section 3 present the research and …

With cryogenic grinding we solve this problem. Thus, the pellets enter the mill and before grinding they are crystallized with liquid nitrogen at sub-zero temperatures to facilitate their breakdown and micronization. Also another advantage of cryogenic grinding is speed: An standard mill usually only reaches 5000rpm (depending on the model).
