How to configure the sand and gravel production line to be more environmentally friendly?
With the continuous expansion of national infrastructure construction, the demand for sand and gravel aggregates is also increasing, and at present, the high pressure of environmental protection, the mining of natural sand is limited, and the supply of sand and gravel aggregates is in short supply, how to solve the dilemma of sand and gravel shortage? Machine-made sand came into being, and has been able to replace natural sand in many fields such as construction. So how is machine-made sand produced, and how should the environmentally friendly sand and gravel production line be configured?
Machine-made sand and gravel aggregate below 5mm is obtained after the original large stone is processed by professional crushing and sand making equipment. Laymen can't help but wonder, how to process large stones into machine-made sand below 5mm?
Take a pebble made of 100cm as an example:
Due to the large particle size of the raw stone, the whole sand and gravel production line is divided into three stages: coarse crushing, medium and fine crushing and sand shaping.
The raw material is 100cm large pebbles through the vibrating feeder evenly fed, through the conveyor belt sent to the jaw crusher for coarse crushing, the coarsely crushed pebbles are screened by the vibrating screen, the unqualified ones are returned to the jaw crusher for re-crushing, and the qualified ones are sent to the next step for fine crushing.
After coarse crushing, the qualified pebbles are sent to the cone crusher and the impact crusher for medium and fine crushing, and then screened by the garden vibrating screen after the medium and fine crushing, and the sand and gravel aggregates that meet the requirements are sent to the finished product warehouse, and those that do not meet the requirements are sent to the sand making machine for sand making and shaping.
The pebbles that do not meet the requirements after medium and fine crushing are sent to the sand making machine for further crushing and shaping, and the finished sand and gravel aggregate can be obtained after crushing and shaping. In addition, according to your own needs, see whether to configure the sand washing machine.
Overview of the whole process:
Pebble raw materials - > vibrating feeder - > jaw crusher - > vibrating screen - > impact crusher cone crusher - > circular vibrating screen - > sand making machine - > sand washing machine - > sand and gravel aggregate finished products.
In addition, environmental protection issues such as noise reduction, dust removal, and sewage treatment must also be dealt with, but the specific configuration of the entire environmental protection sand and gravel production line also needs to be analyzed according to local conditions and specific needs.

How to calculate the investment cost of sand washing field?
Investment costs include procedures, raw material purchase, site infrastructure, sand making equipment, start-up costs, etc., the specific budget according to the raw materials and production scale is different, the actual cost varies greatly, here to provide you with approximate reference data, if you have any questions, you can consult customer service, according to the local economic conditions and policies one-to-one analysis of investment costs and profits.
1. Procedures (about 20,000 yuan).
The process includes: name verification of the industrial and commercial department - mining license of the Land and Resources Bureau - approval of the Safety Administration Bureau - evaluation of the Environmental Protection Bureau - business license of the industrial and commercial department - tax registration certificate of the tax department.
2. Raw materials: (12-35 yuan tons).
The cost of raw material procurement, different regions and types of ores are different, if you have your own mines, you do not need to consider them;
3. Venue: (10,000 years).
Site rent, infrastructure construction costs, including standardized workshops, closed storage warehouses, comprehensive environmental protection facilities, as well as roads, water supply and drainage, power supply and distribution, office and living facilities in the factory area, etc.;If it is a mobile sand production line, there is no need to consider the cost of space.

I am preparing to invest in a sand washing plant, a set of sand washing equipment, with a planned daily output of about seven or eight hundred tons, how can the major shareholder say that he will invest 5 million?I invested 500,000 yuan to account for 10% of the shares. The raw material is subcontracted mountain sand.
There are two doubts:
1. How much is the total investment required for a sand washing field of this scale?Where do you spend it and how much do you share?
2. The washed sand on our side sells for more than 200 yuan, why do you see it on the Internet and say that it is only sold for about 50 yuan?Coordinates Guangxi.

In terms of the current **, the sand field is a profitable project.
The cost of the sand field generally mainly includes the following aspects: upfront investment, equipment, labor, post-maintenance, site costs, etc., which range from 10 to million.
Knowing the cost, let's analyze the profit. According to the statistics of sand and gravel aggregate network in some areas of machine-made sand, Nanjing 97 yuan ton, Changsha 105 yuan ton, Shanghai 95 yuan ton, according to the average price of the machine-made sand market 70 original, a small production line with a daily output of 300 tons is 10,000 yuan a day, and the annual income is 6.3 million yuan after 300 days of operation a year! Although it is a gross profit, it is already very impressive for a small production line.
According to the income accounting of 6.3 million, the input cost is calculated according to 1 million, and the annual profit is about 5.3 million. Therefore, it is not a dream to make an annual profit of one million in the battlefield, if the production scale is mentioned in medium and large, the annual income is at least 10 million.

Sand and gravel aggregates are in short supply, and if high-quality machine-made sand can be produced that can be used in the construction field, it is natural that it will not be able to sell, not to mention the return of profits. However, the current difficulty in handling the EIA procedures has indeed stumped many investors who want to join the sand and gravel industry, so how to pass the EIA? What problems should be paid attention to in the configuration of the production line?
The configuration of the environmental protection sand production line is likely to directly affect whether the EIA procedures are passed, if the sand environment is dusty and the sewage is discharged indiscriminately, then the EIA must not pass. How should the environmentally friendly sand production line be configured? First of all, we should know the basic configuration of the sand making production line:
Vibrating feeder - > jaw crusher - > vibrating screen - > impact crusher Cone crusher - > circular vibrating screen - > vertical shaft impact sand making machine - > sand washing machine - > finished products. Secondly, due to environmental considerations, a closed workshop should be used for processing as much as possible. In addition, the configuration of the equipment in the specific production line is different according to the actual situation, and appropriate changes will be made on the basic configuration, or added or subtracted.
For example, if our raw material is small enough, we can appropriately omit the front-end crushing equipment; If there are no requirements for the cleanliness and mud content of the discharged product, the sand washing step can be omitted, so each equipment is configured according to the specific needs of the specific situation. In addition, at present, for the consideration of environmental impact assessment, environmental protection equipment has also become an indispensable configuration in the sand production line, such as dust collectors, noise suppressors, sewage treatment and other environmental protection equipment. The above is only the general problems that may be involved in the production line, specific to the equipment configuration, investment budget and other issues in the production line, which must be analyzed according to the specific problems such as the raw materials processed by each person, the capacity demand, the discharge requirements, and the application field of finished products.
All in all, although the current environmental protection inspection is strict, and the environmental impact assessment procedures are difficult to pass, there are countermeasures, so those who plan to invest in this area can learn more about it.

Alas, I'm still speechless.
How much does the venue cost per year? What about the labor cost of operations? What about the output? What is the maximum production capacity of the equipment in a day, and the current approximate market profit is 5-7 yuan (the operation is in a better state), and the actual gross profit of my friend is only more than 3 yuan!
I don't know anything, you just invest money, I am also convinced, for example, there is a friend who was killed by environmental protection last year (really unable to meet the standard), the annual gross profit is about more than 6 million. And what about customers? You tell me that there is no inventory, who believes, to what extent the inventory cost has reached, it is all related to doing this line, if the circulation speed is slow, the inventory cost will be higher.
So you can calculate it in three sentences? Brothers!
Generally, large companies are cheaper to take sand locally, you do this, you tell me if you don't have anything to do with it, you're just kidding... Sell it in bulk or wait for death.

There are many procedures for a regular sand field, first of all, the resource exploitation license (which can only be obtained after the bidding, auction and listing of the land and resources department at or above the county level), then the approval of the environmental protection department, and then the approval of the relevant departments of industry and commerce, taxation, safety supervision and other departments of the local government. Very troublesome. Now it's generally a shortcut to clean up the river and level the land.

The market demand for sand and gravel aggregates is self-evident, affected by environmental protection, river sand reserves are far from meeting market demand, and the good prospects of machine-made sand have also attracted many laymen who want to join in, so for laymen, the following procedures are required to open a sand field:
The procedures for opening a sand field: the industrial and commercial department applies for the name and reviews the land and resources bureau handles the mining license, the environmental supervision department conducts the evaluation link, the safety management department conducts the investigation of potential safety hazards, the industrial and commercial bureau issues the business license, and the tax department registers, declares and pays taxes.
If a layman wants to invest in a sand field, he should first understand the basic sand making production line: vibrating feeder jaw crusher vibrating screen cone crusher vibrating screen sand making machine vibrating screen sand washing machine machine-made sand finished products.
The above is a complete sand making production line, but not all sand making production lines need to use all the above equipment, for example, the particle size of the raw material of the machine-made sand is very small, and it can be directly put into the sand making machine-made sand, and the crushing equipment in front is not needed; Or the sand and gravel plant does not need to wash sand, so there is no need to use a sand washing machine.
In addition to understanding the basic sand making production line process, special attention should also be paid to the purchase of sand making equipment, and the function, quality, performance, after-sales service and other factors of sand making equipment should be considered. Before purchasing equipment, it is recommended to shop around, understand the basic information of sand making machine manufacturers, and then determine, it is best to be able to conduct on-site inspections to understand the quality and production process of sand making machine equipment, and secondly, pay attention to whether sand making machine manufacturers can provide perfect after-sales service and spare parts**.

You can do it privately, and it's a lot better.
Guns are generally small-caliber pistol rifles.
The site depends on how big you want to build, it is recommended to go to the already built or the manufacturer to inspect the procedures, you need to prepare materials to the provincial public security department at all levels of management departments to handle, it is very difficult to build a general one or two million.
If you want to know more, you can send me a private message.

It is very difficult to run such a place, and just saying that one of the requirements is approved by the public security department at or above the provincial level, which basically stuckthe vast majority of applicants. It's not that it's not out of nowhere, but in addition to having strength, it also has great personal interest. As far as payment is concerned, it is no longer profitable to run a shooting range with this condition.

First, all firearms must be reviewed at the urban public security bureau for gun qualification certificates and number grabbing, and then the municipal public security bureau reports to the provincial public security department for approval. After the incident, the security forces will inspect all the facilities at your range, paying special attention to the management of guns and bullets, and when things are fine, the guns and bullets must be separated.
Legal analysis. If the flow rate is much lower than the minimum flow rate to ensure accuracy, it will result in no output (e.g., vortex flowmeter) or the output signal will be cut off as a small signal (e.g., differential pressure flowmeter), which is unfavorable and unfair to the supplier. In order to prevent the loss of benefits, for a specific set of thermal energy metering equipment, the supply and demand parties often agree that a certain flow value is "agreed lower limit flow" according to the flow measurement range and the range that can be achieved, and if the actual flow rate is less than the agreed value, the lower limit of the charging flow will be charged. The people's metrology administrative departments at or above the county level may set up metrological verification institutions as needed, or authorize other units of metrological verification institutions to carry out compulsory verification and other verification and testing tasks.
Personnel who perform the verification and testing tasks provided for in the preceding paragraph must pass the assessment. This function is usually implemented in flow meters. According to the needs of the region, the local people's measurement administrative department at or above the county level shall establish social public measurement standard instruments, which shall be used after passing the examination by the people's measurement administrative department at a higher level.
Enterprises and institutions may establish the measurement standard instruments used by the unit according to their needs, and the highest measurement standard instruments shall be used after passing the examination presided over by the relevant people's measurement administrative department. Metrological verification work should be carried out in accordance with the principle of economic reasonableness and in the nearest place. Metrological verification must be carried out in accordance with the national metrological verification system table.
The national metrology verification system table shall be formulated by the administrative department of metrology.
Legal basis. Law of the People's Republic of China on the Administration of Firearms》 Article 6 The following units may be equipped with civilian firearms: (1) Units specializing in shooting competitive sports approved by the provincial-level people's sports administrative departments and for-profit shooting ranges approved by the provincial-level people's public security organs may be equipped with shooting sports firearms; (B) by the provincial level or above the people's forestry administrative departments approved hunting grounds, can be equipped with hunting rifles; (3) Wildlife protection, breeding, and scientific research units may deploy hunting rifles and anesthetic injection guns as needed for their operations. Hunters in hunting areas and herders in pastoral areas can apply for the configuration of hunting rifles.
The areas of hunting and pastoral areas are demarcated by the provincial people**. The specific measures for the allocation of civilian firearms shall be formulated by the public security department in accordance with the principle of strict control, and shall be implemented after being submitted for approval.
