Tattalin fasaha na matakan dakile rushe basalt
During the preparation period of a hydropower station, the sand and gravel processing system encountered the above problems. The raw materials are dense massive basalt and amygdaloidal basalt, with dry compressive strength ranging from 139.3–185.7 MPa and 163.3–172.9 MPa respectively. The total amount of concrete to be processed by the system is about 1.2 million m³, and the production capacity of the system is 154,000 T/month. Among them, the processing capacity of raw material is 560t/h, the production capacity of finished aggregate is 396t/h, and the production capacity of finished sand is 140t/h.
