Recently，A complete set of sand and gravel production line jointly built by China Railway Construction Heavy Industry and China Railway 14th Bureau has been put into use in Wenyu Railway Project.，It marks the first cooperation between the two sides in the field of green building materials production line and achieves phased results.。

DG200-YSHole slag processing production line

The sand and gravel processing project of China Railway 14th Bureau Group Co., Ltd.“Self-operation”Pattern，Mainly processing tunnel slag、Subgrade blasting materials, etc.，Need to fully meet the requirements of Wenling-Yuhuan high-speed railway（Wenyu Railway for short）Subgrade within the scope、Bridge and culvert、Demand for sand and stone materials for tunnel and track engineering construction，The construction period is tight、High standard and other features。

The selected railway construction heavy industryDG200-YSThe tunnel slag processing production line has excellent production flexibility and production performance，According to the demand difference of sand and stone materials of different specifications in different periods.，Dynamically matching the demand of concrete mixing station，The modularization degree is high，The operation is stable and efficient。At the same time，The production line occupies less land.，And that investment is save，Compact layout、Reasonable、Smooth。

  

Carry out equipment training for production and operation personnel on site

Early stage of the project，Railway Construction Heavy Industry Departments Quickly Straighten out Project Progress，Work together to complete equipment selection、Procurement and delivery work。The technical service team is on site to assist the customer throughout，Grasp the golden period of construction，Carry out civil works、Receipt、Installation、Commissioning and training work，Lay a solid foundation for the trial operation of the sand and gravel production line。

At present，Stable sand and gravel production line of Wenyu Railway Project、Highly praised by customers for efficient performance，Smooth trial operation of sand and gravel production。Coming up，Railway Construction Heavy Industry will continue to improve the project.，Strive to create green building materials and equipment quality project。
