Market Analysis: Numerous factors contributing to the rise of machine-made sand

 

Machined sand refers to the sand processed by sand making equipment such as MR-0922 rotor centrifugal sand making machine equipment, the finished product grade is good, the grade is reasonable, and it can be processed into different grades of sand according to different use requirements, which can better meet daily needs. The rise of machine-made sand is influenced by internal and external factors.

External factors: 1. Environmental factors:
the cost of natural sand mining is getting higher and higher After years of continuous mining, natural sand resources are rapidly decreasing, natural sand in many areas has been depleted or close to depletion, and natural sand and gravel are non-renewable resources, some areas and rivers, in order to maintain natural landscapes, protect river embankments and dams, protect ecological balance, regulations strictly prohibit mining.
2. Market factors: With the strengthening of national infrastructure construction, the demand for mechanism sand will continue to increase. The market demand for mechanism sand has expanded from the construction industry to highways, railways, hydropower, metallurgy and other systems, from blocking projects to bridges, tunnels and hydraulic engineering, from masonry mortar to ordinary concrete, reinforced concrete, prestressed concrete, pumped concrete, airtight concrete and spray anchor support and other projects, the market demand is large, it is estimated that the annual output and sales of sand and gravel is more than 100 billion tons, of which the total output of mechanical sand and gravel is nearly 60 billion tons, accounting for more than half of China's sand and gravel production.
3. National policy factors: Since the National Construction Commission formulated the "Technical Regulations for Mechanism Sand Concrete" in 1973, the application of mechanism sand has been widely promoted. In 214, Fujian Province issued the Notice on the Promotion and Application of Mechanism Sand in the Province, in addition, the national macro policy and industrialization, the "Belt and Road" and urbanization process, and the speed of ecological governance have an important impact on the development of mechanism sand.

Internal factors:
The current mechanism sand needs to meet the requirements of the national GB/T 14684-2011 "Construction Sand" standard name changed to "Construction Sand", compared with natural sand, machine sand has the advantages of richer resources and better quality, and can better meet the high strength and high performance requirements
of the modern construction industry1. Raw material advantages: the raw materials of machine-made sand are sufficient, "as long as there is stone, machine-made sand can be produced", urban construction waste and mine tailings can also be developed into machine-made sand raw materials. This not only solves the problem of high price of natural sand and gravel raw materials, but also turns waste into treasure and realizes the recycling of resources.
2. Performance advantages: compared with natural sand, machined sand has higher surface area and hydrophilicity; There is a complete grading; A variety of mineral compositions are available; Stable and adjustable particle grading; The particle shape can be improved, and concrete formulated with machined sand has higher strength and more stable performance.
3. Profit advantage: It is understood from the sand and gravel market that the price of mechanism sand varies from place to place, but it is much cheaper than river sand, so the profit of investing in mechanism sand is considerable. For enterprises using machined sand, the use of machined sand as the raw material for concrete reduces the amount of cement used by more than 35 kg per square of concrete, calculated at 400 yuan / ton, saving 14 yuan per square of concrete, greatly reducing the cost of concrete production.
4. Environmental advantages: the application of machine-made sand in concrete has improved and alleviated a series of environmental problems caused by land destruction and sand dredging.
The influence of internal and external factors makes the mechanism sand become a fairly rapid development of the construction industry investment boom, and with the deepening of the concept of environmental protection, as a domestic mechanism sand equipment and overall solution provider, Maxim has launched green sand making related equipment, the specific equipment and solutions can consult Metto R & D engineers.
