Why is Sand and Aggregate Production Critical? Industry Drivers and Market Opportunities

According to statistics, the global annual consumption of sand and gravel aggregates exceeds 50 billion tons, supporting a $10 trillion + infrastructure market. It is expected to reach a scale of $15.5 trillion by 2030. Sand and gravel aggregates, as raw materials for infrastructure, are facing the predicament of depletion of natural sand resources – due to excessive mining and environmental protection restrictions, the demand for manufactured sand has soared by 40%.

Global sand and aggregate market

1. Basic Materials for Building Facilities

Sand and gravel aggregates are the “basic fuel” for infrastructure projects:

  • Construction: the world consumes about 3 billion tonnes of sand and gravel every year, which is used to produce concrete, mortar, and other materials;
  • Transportation network: a two-way 6-lane highway consumes about 30,000 tonnes of sand and gravel per kilometre;
  • New energy infrastructure: wind turbine tower foundations require high-strength gravel bedding to support the weight of very large turbines; photovoltaic mounting foundations also rely on well-graded sand and gravel aggregates.

2. Natural Sand Depletion Stimulate Mechanism Sand Market:

The formation of natural sand to tens of thousands of years geological process, and human exploitation speed far beyond the natural added. Data from the China Sand and Gravel Association shows that the national natural sand mining volume in 2023 decreased by 42% compared with 2015, but the output of machine-made sand (sand produced by crushing and screening rocks through crushers) soared to 20 billion tons, accounting for 65% of the total sand and gravel consumption. Emerging markets such as Southeast Asia and the Middle East are also facing shortages of natural sand, with the annual growth rate of manufactured sand production capacity exceeding 8%.

A Picture Shows You the Process of Sand and Aggregates Production

As you can see by this picture, producing sand and aggregate involves a series of stages that transform raw rock material into finished products suitable for construction and other applications. At present, the construction industry mostly uses stone crusher plants for sand and gravel aggregate production, and the crushing process is central to this production. Below is a detailed guide on how to produce sand and aggregate through the crushing process:

sand and aggregate production

  • Raw material extraction: Use an excavator, dredger, or blasting to extract raw materials. Transport the materials to the crusher plant.
  • Primary Crushing: A jaw crusher is used to break large rocks into smaller pieces. This step produces coarse aggregate.
  • Secondary crushing: Cone crushers and impact crushers are used to further reduce the size of the material to the required specification.
  • Screening and cleaning: A vibrating screen is used to separate the material by size. The material is then cleaned to remove impurities and improve quality.
  • Stacking and Storage: The processed material is stacked or stored in silos to prevent contamination and ensure easy transportation.

Key Equipment for Sand and Aggregate Production Line- Crusher Machine

Crushing is the “core link” of sand and gravel production. Through multi-stage crushing, the raw materials are gradually reduced from large pieces (particle size > 1 meter) to the target particle size (e.g., 5-20mm, 20-40mm). According to the process stage, there are coarse crushing, medium crushing, fine crushing/shaping equipment.

Jaw Crusher – Rough Crushing

  • Function: Crushing the mined raw ore from 1000mm grade to 100-300mm, reducing the load for subsequent medium and fine crushing.
  • Principle: Crushing between the moving jaw and the static jaw, compressive strength up to 320MPa, suitable for hard rock, high abrasive materials.
  • Selection points: the size of the feed opening should be > the largest particle size of raw materials; discharge opening adjustment (the hydraulic adjustment is more flexible, manual adjustment is low cost); wear parts material (high chrome cast iron liner life than ordinary steel 30% longer).
  • Scenario adaptation: the first choice for coarse crushing in almost all sandstone production lines, especially suitable for hard rock (basalt, granite).

Vertical Shaft Impact Crusher for Sale

VSI Impact Crusher – Fine Crushing/Shaping

  • Function: Crush the material after medium crushing to less than 5-20mm, and optimise the shape of the particles through “shaping” to meet the demand for high-grade sand (such as building sand, glass sand).
  • Principle: Forced shaping by “stone hitting stone” (materials colliding with each other) or “stone hitting iron” (materials hitting metal wear-resistant parts);
  • Advantage: rounded particles, reduce the water demand of concrete; adjustable discharge opening, production of different specifications of sand (such as 0-5mm, 5-10mm).
  • Applicable scenes: mechanism sand production, high standard concrete aggregate preparation.

Impact Crusher for medium crushing

Impact Crusher – Medium and Fine Crushing

  • Function: Suitable for medium-hard materials, with both crushing and shaping functions.
  • Principle: The high-speed rotating plate hammer impacts the material, which rebounds and is crushed by collision with the impact plate.
  • Advantage: good particle shape (less angular, smooth surface), fast processing speed, suitable for limestone, construction waste, etc;
  • Suggestions for selection: choose a multi-chamber impact crusher for medium and low hardness materials (compressive strength ≤ 300MPa), which can take into account the medium crushing and part of the fine crushing.
  • Applicable scenarios: construction waste recycling, small and medium-sized sand and gravel plants.

Cone Crusher – Medium Crushing

  • Function: Secondary crushing of roughly crushed materials to optimize the grain shape.
  • Principle: laminar crushing (simulating the natural crushing process of rocks), squeezing and grinding of materials by moving the cone and the fixed cone;
  • Advantage: high cubic rate of finished products (needle-like particles <15%), low over-crushing rate, suitable for high-grade concrete aggregate;
  • Suggestions for selection: choose a multi-cylinder cone breaker for high-hardness materials (granite, quartzite); the hydraulic system can automatically compensate for wear and prolong the life of the liner.
  • Applicable scenes: high-hardness ore crushing, high-quality aggregate production.

Facing Challenges – Providing Andamine Sand and Aggregate Production Solutions

In the production of sand and gravel aggregates, enterprises often face the challenges of complex raw materials, environmental pressure, site constraints, efficiency, and cost conflicts. These problems directly affect the stability of the production line, cost control, and long-term revenue. Next, I will combine the customer’s specific scenarios to introduce targeted solutions for you.

Challenge 1: Raw materials are complex and difficult to pre-treat?

3-in-1 Impact type mobile crusher plant working onsite

The raw materials for sand and gravel production may be natural ores (granite, basalt), construction waste (concrete blocks, bricks and tiles), recycled aggregates (containing steel bars, plastic impurities), etc. The hardness, humidity, and mud content of different raw materials vary greatly. For example, steel bars mixed in the construction waste will scratch the wear-resistant parts of the crusher.

Solution:

Andamine 3-in-1 mobile impact crusher can be directly equipped with an iron remover + vibrating screen, completing the removal of impurities and grading at the same time of crushing; avoiding the entanglement of rebar and prolonging the service life of the equipment.

Challenge 2: Dusty and polluted?

Andamine Environmetal Stationary Stone Crusher Plant Line

Dust (crushing and screening link), waste water (sand washing link), and noise (equipment operation) in sand and gravel production are the focus of environmental protection inspections. The dust concentration of the traditional production line is too high, which violates the environmental protection policy.

Solution:

Our crushing and screening equipment is equipped with a sealing cover to reduce dust spillage, and the inlet and outlet of the crusher are double sealed, which is less dusty and greener.

Challenge 3: Restricted sites and troublesome switching?

Andamine portable sand and gravel plants

Some sand and gravel plants are located in mountainous areas, suburbs of cities, or temporary mining areas, with small sites and complicated terrain; or they need to adjust their production capacity frequently due to fluctuations in orders. The traditional fixed station needs to be installed by piling, with a long civil construction period (2-3 months), and the transfer site needs to be dismantled and rebuilt, with a high cost (about 30% of the total investment).

Solution:

Andamine mobile crushing plant adopts wheeled or crawler chassis, which can be driven directly to the raw material site; integrates feeding, crushing, and screening in one unit, integrating the crushing process and reducing the operation cost; and it can be put into operation in 14 days from ordering to installation.

Challenge 4: Complex equipment maintenance and high downtime loss?

Sand and gravel production equipment runs at high load for a long time, which is prone to wear and tear of wear-resistant parts (jaws, liners), overheating of bearings, failure of transmission system, etc., which affects customers’ production and brings high losses.

Solution:

Our crushing plant adopts IOT remote monitoring system, which can monitor and control the equipment operation data (such as vibration value and temperature) in real time, and warn the failures in advance (such as abnormal heating of bearings); and it supports 2G/3G/4G network, WiFi, wired network, and so on.

How to Choose A Reliable Supplier of Sand and Aggregate Production Equipment?

When choosing a supplier, you can’t just focus on price; you need to focus on suitability, serviceability and long-term value:

Adaptability:Can the supplier provide customised solutions according to your raw materials (hardness, humidity) and finished product requirements (specifications, grading)? For example, to deal with basalt, you need to choose cone crusher; to deal with construction waste, you need to choose  impact crusher + iron remover.

Service:Does it provide on-site installation guidance, operation training, and 24-hour after-sales response? Andamine has 100+ service outlets around the world, and is available 24 hours online to answer your questions and solve your problems.

Long-term value:The energy consumption of the equipment (e.g. IE4 class motor saves 20% electricity compared with ordinary motor), the life of wear parts (the longer the replacement cycle of wear parts, the lower the cost).
