改质沥青低温造粒生产控制

Process control of modified pitch granulation under low temperature

介绍了多种沥青成型造粒工艺,重点阐述了水下成型造粒工艺控制要点,对沥青造粒温度、沥青成型泵的选择、沥青成型机喷嘴的使用、成型水池水流向、成型后的沥青结块等进行了改进。

Several modified pitch granulating processes are introduced.The new process of pitch pressing under water is described in details.Improvements are made in terms of pitch granulation temperature,pitch molding pump selection,use of nozzle for pitch molding machine,pond water flow and pitch forming,etc..
