What are the advantages of investing in manufactured sand?

The biggest advantage of investing in machine-made sand is the high profit of machine-made sand, the large demand for sand and gravel resources and the large number of raw materials of machine-made sand.

The amount of river sand is limited, but the development of the city is inseparable from the support of sand and gravel aggregates, so machine-made sand has become the main sand and gravel aggregate in the market. Machine-made sand is made of sand produced by stone crushing, screening and sand processing by sand making equipment, and many entrepreneurs obtain high profits by investing in machine-made sand.

The raw material of machine-made sand is a variety of stones, the first stone is usually about 50 yuan tons, and the price of machine-made sand is not less than 100 yuan tons, a small and medium-sized sand and gravel plant can produce 2,000 tons of machine-made sand a day, and the income of a day can reach 200,000, and then remove labor costs, water and electricity costs, site fees and other costs, a day's profit is at least tens of thousands of yuan, and the investment in a good sand and gravel plant can be returned in 3 months.

According to data estimates, the global demand for sand and gravel is growing, and the three major factors of urbanization, population growth and economic development are promoting the growth of sand and gravel aggregates. China's sand and gravel has been in short supply, and the emergence of machine-made sand has solved this problem.

At present, there are many types of stones that can be used to make sand in the sand and gravel industry, and there are about more than 200 kinds of ore materials, such as pebbles, granite, basalt, limestone, dolomite, calcite, tailings, construction waste, etc., which can be used to make machine-made sand, and the quality of machine-made sand produced by different stones is uneven, such as pebbles, river pebbles, basalt, granite and other stones with higher hardness, and the quality of machine-made sand produced is relatively better, which is more in line with the requirements of national building materials.

Investing in machine-made sand has the following advantages: 1The investment is only 1 3-1 5 of the conventional production line with the same processing capacity.

2.The production cost per ton of sand and gravel is only 1 3-1 4 of the conventional production line.

3..The degree of production automation is high, and the production staff per shift is less than 3 people.

4.The investment period is short, and the investment can be recovered in 3 months.

Machine-made sand is after soil removal treatment, crushing and screening of sand making equipment to form rock particles with the following particle size, at present, many areas of the country have begun to produce and use machine-made sand, industrial waste residue, tailings, construction waste and other waste rock can also be used to process into machine-made sand, in recent years, machine-made sand has become a new entrepreneurial field.

1. Advantages of machine-made sand 1. The raw materials for the production of machine-made sand are artificially selected and the materials are systematic.

First, the composition is pure, its chemical composition and mineral composition are basically the same, and the composition is not as complex as natural sand.

2. Fineness modulusGenerally, there is only one fineness modulus of natural sand, and the fineness modulus of machine-made sand can be artificially controlled, which can be adjusted according to their own production needs, which cannot be achieved by natural sand.

3. Adhesion and compressive capacityThe particle matter of machine-made sand is usually arc-shaped, and when it is bonded with concrete structure, it has stronger adhesion and stronger compressive strength.

4. The content of stone powder, machine-made sand and natural river sand is still an important feature, that is, the stone powder content of machine-made sand, and the content of machine-made sand and gravel powder does not exceed 20%, which has no unreasonable effect on the coagulation and strength of concrete.

2. How to choose the equipment of the machine-made sand production line? The equipment of the machine-made sand production line mainly includes: vibrating feeder, jaw crusher, cone crusher, impact sand making machine, vibrating screen, three-in-one sand washing machine, belt conveyor and other equipment, and the mobile sand making machine has also received more and more attention as the older it gets.

When purchasing machine-made sand production line equipment, it is necessary to consider factors such as machine-made sand raw materials, production sites, finished sand specifications and investment funds, and purchase suitable sand making equipment.

Due to the shortage of natural sand resources and environmental reasons, the cost of natural river sand and sea sand is getting higher and higher, and it is currently unable to meet the growing demand of the market. In summary, it is feasible to use high-quality machine-made sand to meet the demand for construction sand in areas where natural sand resources are scarce, and it also has considerable comprehensive benefits.

Machine-made sand is made by crushing and screening after soil removal treatment, and the particle size is smaller than that of rock, mine tailings or industrial waste residue particles.

Machine-made sand refers to the sand processed by machine-made sand and other equipment, which can make the desired size of sand according to their own requirements and meet different process requirements.

Manufactured sand is the sand that people make through sand making machines and those electronic devices. Sand making machines make different sand according to the different uses of sand, which has played a certain role in the current construction industry.

Machine-made sand refers to rock particles with a particle size smaller than those made by mechanical crushing and screening after soil removal treatment. It is mainly to crush and screen the ore (pebbles, granite, basalt, bluestone, limestone, etc.), and artificially process it into sand and gravel particles that meet the particle size requirements. There are many kinds of raw materials used in the production of manufactured sand, in addition to the commonly used pebbles, there are also industrial waste residues, construction waste, and waste rock.

River sand is a natural sand, which is mainly formed by the impact of natural forces.

Machine-made sand is made of mechanical crushing and screening of rock particles smaller than the grain warp, which can be comparable to natural sand in terms of physical and chemical properties. So what are the advantages of manufactured sand?

1. The machine-made sand has excellent particle shape, less needle flakes, and is mostly cube, which increases the contact surface with the cement slurry, has good bonding ability, good workability, and makes the concrete more compact;

2. The gradation of machine-made sand production is adjustable, and the finished sand grade is reasonable;

3. The mud content is small, the mud block content is small, and the admixture of solid concrete is small;

4. The initial slump performance of the concrete of high-quality machine-made sand is better, the expansion degree is larger, the loss over time is smaller, and the concrete performance is more superior.

In addition, the advantages and use of manufactured sand are also reflected in the following aspects:

1. Machine-made sand is wide and rich in resources.

River sand resources are in short supply, and the state has increasingly monitored river sand mining, and many places have banned mining. Machine-made sand can be directly processed from a variety of ores, which is relatively rich in resources.

2. Machine-made sand and materials are easy to integrate.

River sand is usually washed by water flow and has a relatively smooth surface, while machine-made sand has many cross-sections and rough surfaces, and machine-made sand particles can be better combined with cementitious materials such as cement.

3. Machine-made sand can achieve environmental protection.

The raw materials of machine-made sand can be used for some solid waste, and at the same time, a large amount of construction waste can be crushed through mobile crushers in urban planning and construction, which is used to produce and process recycled aggregates, which not only solves the problem of environmental pollution, but also improves the utilization rate of natural resources.

4. Machine-made sand is cheap.

River sand resources are tight, so the first is getting higher and higher, and the machine-made sand is not the same in various places, but it is basically much cheaper than the river sand, and compared with the river sand, the machine-made sand is about 20-30 yuan cheaper per ton. It can reduce the production cost of the enterprise.

In short, the application technology of high-quality machine-made sand in building aggregates has matured, comparable to natural sand, which can not only protect natural sand resources, maintain ecological balance, but also meet the demand for construction sand and improve the quality of sand and gravel aggregates, killing two birds with one stone.

As an indispensable raw material for infrastructure construction projects such as roads, bridges, water conservancy and hydropower, highways, and railways, aggregates are increasing in demand for sand and gravel aggregates worldwide, and manufactured sand is being promoted.

It has become the general trend, so how should China promote machine-made sand?

Global sand and gravel market demand: continues to grow.

It is estimated that the global production of sand and gravel is about 40 billion tons. It is expected that the global sand and gravel industry will remain positive in 2030. Population growth, economic development, and global urbanization are driving the growth of the sand and gravel industry, and global sand and gravel production is expected to reach 60 billion tons by 2050.

The total production capacity of the world's top 20 sand and gravel producers accounts for less than 5% of the global total, and the remaining 95% of the sand and gravel production capacity is extremely scattered, which makes it challenging to grasp accurate data.

At present, China has introduced a series of policies to support the development of manufactured sand and domestic manufactured sand production technology.

A breakthrough has been made to replace natural river sand with manufactured sand.

It is the trend of the times and the imperative.

Manufactured sand promotion policy.

It is necessary to adhere to the planning first, adapt measures to local conditions, scientifically select sites, and pay attention to scale;
