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.
Must-have Equipment For The Sand And Gravel Aggregate Industry
The sand and gravel aggregate industry requires the use of a variety of equipment for mining, processing, production and transportation. Below are some of the common equipment suitable for the sand and gravel aggregate industry, as well as their functions and roles:
Mining
- Excavator: Mainly used for mining raw ore or ores on the surface or underground, and digging them out for subsequent processing or transportation.
- Loader: Used to load the excavated raw ore or ores onto transportation vehicles or conveyor belts for transportation or processing.
- Down-the-Hole (DTH) Drilling:The rigs use a hammer and drill bit to penetrate the earth. It is crucial for tasks such as blast hole drilling and exploratory drilling in mining.
Processing
- Crusher: Crushes large pieces of raw ore into smaller particles by crushing, impacting, etc. for subsequent screening and processing.
- Screening Machine: Screening and sorting the crushed material according to particle size to obtain products and by-products that meet the requirements.

Application Areas of Sand and Gravel Aggregates
Concrete preparation
Road construction
Building construction
Infrastructure construction
Railway engineering
Water engineering
Landscaping
Environmental Projects
Decorative Use
Concrete preparation
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.
Road construction
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.
Building construction
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.
Infrastructure construction
Such as bridge construction and tunnel construction also require large quantities of sand and gravel aggregates as building materials.
Railway engineering
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.
Water engineering
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.
Landscaping
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.
Environmental Projects
Gravel aggregates are also used in certain environmental projects, such as as filtering materials in rainwater collection and filtration systems to help remove pollutants.
Decorative Use
Specific types of aggregates, such as colored gravel, can be used for indoor and outdoor decoration to provide a beautiful visual effect.
Raw materials for producing sand and gravel aggregates
Granite
A high quality raw material for construction aggregates due to its high hardness and wear resistance.
Limestone
The material of choice in some regions for manufacturing cement and producing fine aggregates.
Basalt
With good abrasion and compression resistance, it is suitable for use as aggregate for pavement and construction.
River pebbles
After being processed in a crusher, they can be used as a high quality concrete aggregate.
Shale
Certain types of shale can be used for specific types of construction projects after crushing and screening.
Quartz sand
Moderately hard sandstone can be used as construction aggregate.
