Cryogenics

As the cryogenic grinding system cools down from ambient temperatures during startup, the system components will shrink. For example, a 10' length of stainless steel piping will shrink by more than 0.125" (3 mm) as it cools from ambient to -100°F (-73°C). A longer pipe will shrink even more. Therefore, the grinding system must be designed to
