I wanted to open a sand quarry right next to the Yellow River, but I didn t know what equipment I ne

What equipment do I need to buy to open a sand field?

The popularity of the machine-made sand industry has not decreased, and people have come to consult about investment in sand plants. How to configure the sand making production line?

The same is to invest in a sand plant, the situation is different, the demand is different, and the equipment required may be different. First, consider our raw materials. The feed port of the conventional sand making machine is generally less than 5 cm, if our stone is too large, the crushing equipment at the front end is indispensable.

In addition, we need to pay attention to the fact that we need to determine how many stages we need to crush according to the size of our rough stone. The number of crushing stages required depends mainly on the maximum strength of the ore, the particle size required for discharge, and the achievable crushing ratio between the crushing stages.

For example, the particle size of our raw ore is 120cm, and the particle size of the finished product is required to be 1cm.

If a section of crushing is used, the crushing ratio of the production stage is i1=120 1=120, and it is obvious that this crushing ratio is too large, and a section of crushing cannot be achieved at all.

What about the two broken sections? i1*i2=120, the average crushing ratio of the two stages is 11, which is still large.

Is the three-stage crushing ratio appropriate? i1 * i2 * i3 = 120, the average crushing ratio of the three stages is 5, which is more appropriate.

Therefore, in the absence of special requirements, when the particle size of the raw ore is 120cm and the particle size of the finished product is 1cm, it is more appropriate to choose three-stage crushing.

Finally, we should know what crushing equipment is suitable for different crushing effects.

Coarse crushing: represented by jaw crusher, it is divided into PE jaw crusher, PEW European jaw crusher and other series.

Medium and fine crushing: represented by cone crusher and impact crusher, cone crusher is suitable for stone above medium hardness, and impact crusher is suitable for stone with soft hardness.

Sand making: At present, there are most vertical shaft impact sand making machines on the market, and the feeding material is below 5 cm, and the finished product is less than 5 mm.

In addition to conventional crushing and sand making equipment, the current high pressure of environmental protection policies, the equipment of certain environmental protection facilities is also very necessary.

1.Reasonably configured production line: closed production line can be adopted to suppress dust; Add a dust collector to the production line.

2.Noise pollution, which we can avoid by choosing high-quality, low-noise equipment to comply with environmental regulations.

3.Plants are planted around the production line to reduce noise and dust.

4.For wastewater, we can classify it, domestic wastewater or processed stone wastewater, and after classification, it is treated by a specific system, and (often using a filter press) can be recycled as production water.

The configuration of the whole sand making production line:

Raw materials - > vibrating feeder - > jaw crusher - > vibrating screen - > impact crusher Cone crusher - > circular vibrating screen - > sand making machine - > sand washing machine - > finished sand and gravel aggregate.

Note: The environmental protection equipment involved is not added due to different local policies, and you can consult specifically if you want to know more about it).

Sand dredging ship, that is, the mechanical equipment and tools for mining sand and gravel and sand ore, are generally electric mobile or diesel mechanical powered. The hull adopts an assembled box structure. It is equipped with excavation device, screening device, lifting device, conveyor device, etc.

The motor drives the bucket to feed, the stones are passed out by the conveyor belt through screening, and the sand is transmitted to the designated place by the conveyor belt.

Yes Yes is such sand mining equipment.

There is also the need to prevent people from various bureaus from checking on you.

River sand mining requires the following procedures:

1. Submit an application for river sand mining to the local water administration department;

2. At the same time as submitting the application, relevant materials must be submitted, such as a copy of the business license and the applicant's valid identity certificate; Relevant certification documents of river sand mining equipment and corresponding technical personnel; Feasibility demonstration report and expert review opinions of river sand mining project; Agreements with interested third parties;

3. If the materials are complete and the procedures are legal, the relevant departments will approve and issue the river sand mining license and legally engage in sand mining;

4. The river sand mining permit for the main flood channel shall be examined and approved by the provincial people's water administrative department; The sand mining permit of the general flood river shall be examined and approved by the people's water administration department of the city divided into districts and counties in accordance with the river management authority.

The sand in the river can be legally taken by individuals or units, and when there is a need for sand mining, an application can be submitted to the local water administration department, as long as the reasons in the application are reasonable and the materials submitted are complete, the request will generally be accepted. Unauthorized sand mining without approval of an application may constitute a criminal offence.

Legal basis: Article 343 of the Criminal Law of the People's Republic of China.

Illegal Mining] Violating the provisions of the Mineral Resources Law by mining without obtaining a mining license, entering a mining area planned by the state, mining areas of great value to the national economy, or mining areas of others without authorization, or mining specific minerals that the state provides for protective mining, and the circumstances are serious, shall be sentenced to fixed-term imprisonment of not more than three years, short-term detention or controlled release, and/or a fine; where the circumstances are especially serious, the sentence is between three and seven years imprisonment and a concurrent fine.

Crime of destructive mining] Whoever, in violation of the provisions of the Mineral Resources Law, adopts destructive mining methods to exploit mineral resources, causing serious damage to mineral resources, shall be sentenced to fixed-term imprisonment of not more than five years or short-term detention and shall also be fined.

Legal analysis: the need for the Bureau of land and resources to apply for a mining license, ore belongs to state-owned resources, the mining license will stipulate the scope of sand and gravel mining, so it is very necessary to apply for a sand and gravel mining license to the national or local Bureau of land and resources, and the environmental supervision department is required to test, and other procedures can be consulted with the relevant local authorities.

Legal basis: "Administrative Licensing Law of the People's Republic of China" Article 29 Where citizens, legal persons or other organizations engage in specific activities and need to obtain an administrative license in accordance with law, they shall submit an application to the administrative organ. If the application needs to be in a format text, the administrative organ shall provide the applicant with a format copy of the application for administrative licensing.

The format text of the application shall not contain content that is not directly related to the application for administrative licensing.

Because the sand in the Yellow River cannot be directly used in construction, the sand contains various impurities, and the water of the Yellow River is relatively turbulent, if you want to salvage the sand, it is not an easy thing, and the sand needs to go through a series of processing after salvage, so the cost is too high.

The Yellow River in China is famous for its sediment. Ancient Chinese books record that "the Yellow River fights water, and mud dwells in its seventh". According to the analysis of modern measured data, the average annual sediment transport into the main stream of the Yellow River is 1.6 billion tons, and the sediment content is 35 kilograms and cubic meters.

The Yellow River has a large amount of sand and a large amount of sediment, and is the highest among the world's major rivers.

Sediment accumulation in the lower reaches of the Yellow River not only occurs in the riverbed, but also in the Ningmeng section of the middle reaches of the Yellow River. The Ordos Plateau in the Ningmeng River section is a rainstorm-prone area in the middle reaches of the Yellow River. In the rainy season, heavy rains often occur here, and the flood carries a large amount of sediment directly into the Yellow River, silting up the riverbed, forcing the main stream of the Yellow River to move northward, directly threatening the Baolan railway and highway, causing great harm.

Summary. Dear, I'm glad to answer for you: No.

According to the river sand mining management system, sand mining, soil extraction, gold panning, and discarding sand and gravel or silt within the river management area must be approved by the competent river authority; If other departments are involved, it shall be approved by the competent authority of the river in conjunction with the relevant departments. River sand is an important building material used to make concrete and is the foundation for the construction of high-rise buildings. Over-exploitation of river sand is likely to cause damage to the geology of the levee, and the structural instability of the dam will lead to collapse, with unimaginable consequences.

Extracting river sand also affects the ecological environment and is likely to destroy local biodiversity.

Over-exploitation of river sand is likely to cause damage to the geology of the levee, and the structural instability of the dam will lead to collapse, with unimaginable consequences. Extracting river sand can also affect the ecological environment and is likely to damage local biodiversity.

If the sand is removed to benefit the flow of water in the river and does not cause damage to the embankment, can it be dug up?

Dear, I'm glad to answer for you: Excessive mining of river sand is likely to damage the geology of the embankment, and the dam will collapse if the cluster structure is unstable, and the consequences are unimaginable. Extracting river sand also affects the ecological environment and is likely to destroy local biodiversity.

Legal Analysis: Illegal mining of river sand is suspected of constituting the crime of illegal mining. Whoever refuses to stop mining after being ordered to stop mining, causing damage to mineral resources, shall be sentenced to fixed-term imprisonment of not more than three years, short-term detention or controlled release, and/or a fine; and where serious damage to mineral resources is caused, a sentence of between three and seven years imprisonment and a concurrent fine is to be given.

Sand mining within the scope of river management, in any of the following circumstances, shall be convicted and punished as the crime of illegal mining: (1) In accordance with the relevant provisions of the river sand mining permit shall be handled, the river sand mining license has not been obtained; (2) In accordance with the relevant provisions, the river sand mining license and mining license shall be handled, and the river sand mining license has not been obtained, and the mining license has not been obtained.
