    Abstract： Up to now， there are two kinds of rubber comminution processes： comminuting by direct cutting in normal atmospheric temperature condition and cryogenic comminution and the latter includes liquid nitrogen refrigeration comminution method and air expansion refrigeration comminution method. Compared with the former， the latter has obvious advantages in fine rubber powder production except for huge investment and production costs. The process of utilizing LNG cold energy for waste rubber cryogenic comminution in satellite station is applied rarely in domestic LNG terminals and the technology is relatively scarce. In the technology， using air as a middle cold medium， cold flow generated in LNG vaporization is recovered to cool air and then the cooled air is sprayed to cool rubber powder. Simulation results show that this rubber comminution process has remarkable energy conservation effects and energy consumption of fine rubber powder per ton can be reduced by 349.5kW·h.
