| Abstract: |
| A new technology of waste rubber dynamic desulfurization including intermittent unloading from several devulcanizers，continuous transportation by screw conveyor and cooling in agitator tank could be used to effectively reduce environmental pollution in the current desulfurization process. Based on this new equipment， a theoretical calculation method was developed to analyze the screw transportation and heat transfer ability.The influence of force exerted on materials and friction on the conveying process was analyzed，the parameters of screw transportation was designed and verified，and the heat equilibrium of cooling process was calculated. |
