The production process of rubber powder includes room temperature crushing, low temperature freezing crushing, water impact and so on. Compared with reclaimed rubber, rubber powder does not need desulfurization, so the production process consumes less energy than reclaimed rubber, and the process is simpler.

The main production methods of reclaimed rubber are oil method (direct steam static method), water oil method (cooking method), high temperature dynamic desulfurization method, extrusion method, chemical treatment method, microwave method, etc. The main manufacturing methods of reclaimed rubber in China are oil method, water oil method and high temperature dynamic desulfurization method to prepare reclaimed rubber.
