In response to the national industrial policy requirements on "supporting the use of tailings and industrial solid waste to produce sand and gravel aggregates" and "relying on resources such as tailings and construction waste to build new sand and gravel aggregate production bases", the company actively integrates relevant resources, Using limestone tailings waste to produce sand and gravel aggregate, we invested in the construction of a sand and gravel aggregate production line with 10-25MM, 5-10MM, 0-5MM aggregate and machine-made sand as the main products, with an annual output of 3 million tons. The total investment 63.26 million yuan.

The sand and gravel aggregate production line adopts the most advanced domestic sand and gravel aggregate production technology and low energy consumption, high environmental protection equipment, fully enclosed operation, centralized computer control, green and automated production process, and belongs to large output, low energy consumption, high environmental protection The new generation of green and environmentally friendly sand and gravel aggregate production line has not only improved resource utilization, but also promoted the structural adjustment of the construction sand and gravel aggregate industry, which has significant economic and social benefits.
