The sand and aggregates industry is an industry that involves the extraction, processing, and sale of sand and stone, which are the basic building materials used in various projects such as building, road construction, and bridge construction. The industry is a fundamental and important part of the global landscape, playing a key role in driving economic development and meeting the infrastructure needs of society.
Fine sand: grain size is about 5mm.
Crushed stone has a wider range of particle sizes, which can vary from a few millimeters to tens of centimeters, depending mainly on the purpose of use. Such as, when it is used to be keyston, the size is about 30-50mm.
The size of concrete aggregate is about 10-20mm or 10-30mm.
The size of asphalt aggregate is about 5-10mm.
In concrete, sand and gravel aggregates occupy most of the volume and are used to provide strength and structural stability to the concrete. Both fine aggregates (e.g. sand) and coarse aggregates (e.g. gravel) are indispensable components in the production of concrete.
Sand and gravel aggregates are used as paving materials in road construction, including the base and surface layers of roads. They are able to withstand heavy pressure and wear and tear from vehicle traffic.
In construction, sand and gravel aggregates are used in the manufacture of building materials such as blocks, prefabricated elements, bricks, and as part of the foundation, walls and roof of a building.
Such as bridge construction and tunnel construction also require large quantities of sand and gravel aggregates as building materials.
Sand and gravel aggregates are often used for the bedding underneath railroad tracks, which helps to spread out the loads borne by the railroad tracks while providing stable support.
In the construction of dams, embankments, harbors and ports, sand and gravel aggregates are used as an important ingredient in concrete or for filling to increase the stability and durability of the structure.
Selected sand and gravel aggregates are widely used in outdoor landscaping, such as the decoration of sidewalks, courtyards, and flower beds, due to their natural color and texture.
Gravel aggregates are also used in certain environmental projects, such as as filtering materials in rainwater collection and filtration systems to help remove pollutants.
Specific types of aggregates, such as colored gravel, can be used for indoor and outdoor decoration to provide a beautiful visual effect.
A high quality raw material for construction aggregates due to its high hardness and wear resistance.
The material of choice in some regions for manufacturing cement and producing fine aggregates.
With good abrasion and compression resistance, it is suitable for use as aggregate for pavement and construction.
After being processed in a crusher, they can be used as a high quality concrete aggregate.
Certain types of shale can be used for specific types of construction projects after crushing and screening.
Moderately hard sandstone can be used as construction aggregate.
Used to transport concrete from the mixing plant to the construction site to maintain the uniformity and fluidity of concrete.
Self-loading Concrete Mixer Truck is used for mixing concrete raw materials (cement, sand, stone, etc.) and water to form concrete, and transporting the concrete to the construction site through the self-unloading function of the vehicle, which is suitable for small-scale building construction, municipal engineering and other occasions.

In fact, if we do all the above steps, we will surely be able to help our customers to successfully increase the return on investment, but this is far from being our pursuit, we will also carry out continuous improvement and technological upgrading for crushing equipment to enhance our mutual competitiveness.
Sand and gravel aggregates are the basic materials for construction projects, and their sufficient supply and good quality directly promote the development of infrastructure, including the construction of roads, bridges, houses
Sand and gravel aggregates are a natural resource, especially in many areas where these resources are relatively abundant and renewable. Sustainable utilization of the resource can be ensured through proper mining and management.
Sand and gravel aggregates are available in a wide range of sizes and uses and can be customized to meet the needs of construction projects. From foundation filling to concrete production to paving, sand and gravel aggregates play an role.
The gradual recovery and growth of the global economy will lead to the development of the construction industry, which will increase the demand for sand and gravel aggregates. Economic growth also means more money for infrastructure
Many governments have adopted policies to support infrastructure development and sustainable development, which provides policy support and legal safeguards for the development of the sand and gravel aggregate industry.
A strong infrastructure network can promote the development of transportation, logistics, tourism, commerce and other related industries, forming a virtuous economic cycle.
