呼和浩特抽水蓄能工程砂石系统运行后,因大理岩的产粉率远高于原设计的预计量,在运行过程中,制砂车间难以承受高含粉洗砂能力,制砂环节成了控制整个系统的产能瓶颈。通过对原工艺设计改造,解决了制砂高产粉控制工艺问题,为今后在北方干旱地区建造高产粉料源积累了设计经验和运行管理经验。 After the operation of sand and gravel system of Hohhot Pumped Storage Engineering, the production rate of marble is much higher than the predicted amount of the original design. During the operation, the sand making workshop can not afford high powder and sand washing ability, The entire system capacity bottleneck. Through the original process design and reform, to solve the sand production of high-yielding powder control process for the future in the northern arid areas to build high-yield powder source has accumulated design experience and operation management experience.
