Reduction Sheer Cryogenic Pulverizers

Cryogenic pulverizing or grinding, is the act of cooling or chilling a material and then reducing it into a small particle size. For example, thermoplastics are difficult to grind to small particle sizes at ambient temperatures because they soften point. Cryogenic Pulverizing takes advantage of both the cryogenic temperatures and conventional mechanical milling. The extremely low milling temperature suppresses recovery and recrystallization and leads to finer grain structures and more rapid grain refinement. The embrittlement of the sample makes even elastic and soft samples grind able. Tolerances less than ~5 µm can be achieved depending on the materials. All of which can be tested at our center of excellence in Kent, Ohio.

REC 100

Our systems use liquid nitrogen to cool down a feed material prior to and/or during milling to either help prevent its melting or decomposition, or achieve embrittlement. While each product is unique, rates will vary.
