What are the advantages of manufactured sand and how to use it?

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 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 become more and more monitoring of 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.

The surface of river sand is usually smoother after water flow, while the machine-made sand has many cross-sections and rough surfaces, and the 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 by 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.

The difference between manufactured sand and river sand is mainly reflected in four aspects: material, longevity, environmental protection, and cost.

1. Material

Machine-made sand is made by sand making equipment such as sand making machine, although the technology of sand making equipment has made great progress to meet production needs and construction requirements, but natural sand is formed by long-term seawater impact, and natural sand is more suitable for construction sand needs in terms of material alone.

2. Permanence

There are many types of sand and gravel raw materials for machine-made sand, and there are abundant resources, so there is no need to worry about the shortage of materials in the process of use, and natural sand is a natural resource, which needs to be formed after long-term seawater impact, and river sand resources are in short supply, and it has been strictly supervised and prohibited from mining, so it is not long-lasting. In terms of longevity, manufactured sand is better than natural sand.

3. Environmental protection

The particle size of machine-made sand can be adjusted to meet the production needs of different users by adjusting the sand making equipment, and many sand making equipment has environmental protection functions and can be used for tailings treatment; The mining of natural sand is generally carried out in the river, and the mining of natural sand in large quantities will cause certain damage to the ecological environment such as rivers and beaches. Therefore, from the perspective of environmental protection alone, machine-made sand is more environmentally friendly than natural sand.

4. Cost

River sand is a scarce resource and is becoming more and more expensive. Machine-made sand is different in various places, but it is basically much cheaper than river sand.

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.

River sand has soared, and it has become an inevitable trend for machine-made sand to replace river sand, as one of the concrete materials, can machine-made sand completely replace it and apply it to concrete? What are the advantages? How is it different from river sand?

River sand is mainly distributed in the vicinity of rivers, and with the continuous expansion of infrastructure construction in the country, the amount of river sand is gradually increasing, and the amount of river sand mining is bound to be controlled for the protection of the environment. At present, manufactured sand, which is used as a substitute for river sand, has been widely used in the construction field. Machine-made sand used to replace river sand usually refers to sand less than 5 mm, and the raw stone is processed by professional sand making equipment.

1.Machine-made sand is different from river sand.

1) The content of machine-made sand and gravel powder is relatively high, but some professional equipment can control the content of machine-made sand and gravel powder, so that it is used to configure concrete and natural sand. Machine-made sand mainly detects the content of stone powder, river sand detects the mud content, and other detection indicators are basically the same.

2) In addition, the machine-made sand particles are relatively irregular, but this tends to make them have a better degree of adhesion.

3) Secondly, the raw materials of machine-made sand are very sufficient, which can meet the demand for sand and gravel aggregates.

4) Thirdly, although the solidity of machine-made sand is slightly worse than that of river sand, according to research, it can still reach the index of excellent products, and can completely replace the use of river sand in concrete.

The above benefits of machine-made sand compared with river sand are all for high-quality machine-made sand, but some sand making equipment is poor, and it is possible that the machine-made sand produced does not meet the requirements of concrete configuration. Therefore, it is necessary to be familiar with the process and equipment selection of manufactured sand.

2.Manufactured sand processing process.

In the selection of sand making equipment, vertical shaft impact sand making machine is widely used. However, suitable for most people does not mean that it is suitable for themselves, or according to their own raw materials, production capacity, applicable areas and other needs, contact manufacturers to configure appropriate equipment models and processing lines, if necessary, you can also go to their customer sites and processing plants for inspection and testing.
