| Abstract: | The primary parameters and working principle of crude terephthalic acid(CTA) rotary drying machine were introduced. The failure of CTA rotary drying machine was analyzed.The reformation scheme was suggested on the spiral feeder,riding wheel and shaft seal of the drying machine and proved to be reliable and safety.The abrasion can be reduced and the service life of feeding material can be prolonged by applying cantilever-type spiral feeder,riding wheel with the support at the both ends of the bearing and large bearing location-type tube structure. |
