随着我国基础建设的大规模进行,砂石料需求量越来越大.而自然资源有限,国家实行的环保政策使大量碎石厂因环保不达标而被迫关闭.为了保证工程施工,本文从隧道洞渣选取、碎石场生产设备选型、生产过程控制着手,详细介绍了隧道洞渣制备碎石的生产工艺.%With the large-scale infrastructure construction in China, the demand for aggregate is growing. However, due to limited natural resources, a large number of gravel plants have been forced to shut down because of the environmental protection policies implemented by the state. In order to ensure the construction of the project, this paper introduces the production process of crushed stone from tunnel cinder in detail from tunnel cinder selection, grading equipment selection and production process control.
