In July 2020, it obtained the mining right of the dolomite mine for building stone materials, with a recoverable reserve of 310.631 million tons and a production scale of 20 million tons per year. With the smooth delivery of finished aggregates of different specifications to storage, the 500-600 tons per hour dolomite aggregate crushing plant has recently entered the trial operation stage.
The sand and gravel aggregate processing system is designed with a processing capacity of 500 t/h, a production capacity of 450 t/h, and a monthly processing capacity of 175,000 tons. It can produce four different specifications of finished aggregates.
Production process: dry method
Finished material specifications: 0-5-10-20-31.5 mm
Finished material use: sold to the sand and gravel market
Equipment: C6X125 jaw crusher, CI5X impact crusher, F5X1360 vibrating feeder
Three equipments complete the crushing work with an output of 500 tons per hour, with high efficiency, less equipment and low maintenance cost.
This project is a mine restoration and treatment project, which has both environmental protection and social benefits.
The performance of the project in terms of cost control, profit improvement, and social benefits:
- The number of equipment is small, and the labor costs and maintenance costs are naturally less. With the use of Siemens energy-saving motors, the average power cost per ton of stones is lower.
- Good market conditions for aggregates and quick returns.
- Environmental restoration and governance projects have environmental and social benefits.
