China
is a big country of sand and gravel resources and also a big country of
consumption, with more than 10 billion tonnes of sand and gravel
aggregates used for roads, bridges, buildings and other infrastructure
projects every year.
The upper reaches of the Yangtze River are
rich in sand and gravel resources, and the reservoir silt sand reserves
are considerable. Driven by interests, illegal sand mining in the
Yangtze River Basin was once very rampant, and the "blood-sucking"
savage sand mining has led to some sections of the river facing
dangerous situations such as bank failures, which seriously affects the
stability of the Yangtze River, flood safety, normal navigation, and
damages the water environment.
In recent years, the Yangtze River sand mining management system has been improved, forming a mechanism in which the competent water administration department is the main organisation and other departments work together, and the local administrative head's responsibility for local management is constantly being strengthened. "After years of exploration, the "Yangtze River model" has been formed, which is based on the law, the government is responsible for the overall responsibility, the water conservancy is the leading role, and the departments cooperate with each other, and the efficiency of combating and remedying illegal sand mining has been greatly improved."
Recently, the Guizhou Provincial Office of River and Lake Governance issued a programme scheduled for September to October to carry out the 2023 River and Lake Governance Supervision and Joint Law Enforcement Supervision of Rivers and Lakes, which includes cracking down on sand and gravel piracy in the Yangtze River Basin in accordance with the law.
The scope of this supervision for Guizhou Province, nine cities (states) and their jurisdictions not less than one-third of the county (city, district), the supervision includes the comprehensive promotion of administrative law enforcement "three systems" situation, the safety protection of rivers and lakes to carry out special law enforcement action, as well as the situation of the Yangtze River Basin in Guizhou Province to combat and rectify the illegal mining of sand, and so on.
Guizhou Province requires:
Crack down on illegal and criminal activities of stealing sand and gravel from the Yangtze River Basin or digging and mining indiscriminately in excess of the scope, deadline and quantity in accordance with the law; crack down on illegal and criminal activities of stealing and illegally selling sand and gravel from the Yangtze River Basin under the disguise of dredging operations, government projects, etc. in accordance with the law; and rectify, in accordance with the law, quarrying areas with loose sand-related management, sand and gravel trading places, and key areas with high and frequent incidence of illegal sand mining.

The rocks are harder because of there is iron ore inside. The project uses 600*130 vibrating feeder, PE1000*1200 jaw crusher, two HST300 single cylinder cone crusher two, two JYS1238 sand making machine, four vibrating screen, four sand washing machine, one sand recovery machine, capacity design is 300t/h.
This project is a sand making production line with an hourly output of 200 tons. The equipment used includes vibrating feeder, single cylinder cone crusher, multi-cylinder cone crusher, sand making machine, 4 vibrating screens, 4 sand washing machines and sand recovery&dehydration integrated machine.
The equipment aspect of this project includes PE870*1060 jaw crusher, PF1515 impact crusher, JYT5145 sand making machine and two 2470 vibrating screens. The equipment is used for limestone crushing and sand making. Shaanxi Province is rich in limestone resources and has many limestone aggregate plants, and this set of equipment from Jianye Company has good feedback in the local area.
The production line adopts the high-pressure mill and environmental protection equipment produced by Jianye Heavy Industry, using advanced grinding process technology to start the construction of an annual output of 50,000 tonnes of slag micro-powder production line project.
The user uses calcined petroleum coke to grind and make powder, and the finished coke powder is mainly used for processing graphite electrodes. In recent years, the price of coke powder rises, the user spends tens of millions of dollars to build a production line with an annual output of 60,000-100,000 tonnes of high-quality coke powder, which is the first phase of the project, using two sets of 6R4528 high-pressure grinding mills of Jianye Company.
