In 2021, Guangzhou’s total consumption of manufactured sand reached 8.3 million tons, a year-on-year increase of 320%. Manufactured sand accounted for 18.69% of all sand used, up 10.89 percentage points from the previous year. In state‑owned investment projects, the share of manufactured sand exceeded 20%, reflecting a robust upward trend in its adoption across construction works. Meanwhile, Shanghai’s growth in manufactured sand usage was even more remarkable: in 2021, the city’s total sand consumption for construction amounted to 52.752 million tons, a 32.7% year-on-year rise. Notably, natural sand consumption declined by 40.7% year on year, while manufactured sand usage surged by 1,329.2% over the same period.

In first-tier megacities such as Guangzhou and Shanghai, the use of manufactured sand has surged dramatically, clearly demonstrating strong market demand and setting a leading example nationwide. The prospects for the manufactured‑sand market are exceptionally promising. Two key factors determine the quality of manufactured sand: first, the characteristics of the parent rock—primarily its physicochemical properties—and second, the production equipment and processes employed. China boasts abundant and substantial rock resources; limestone, granite, pebbles, and other materials are widely distributed across the country, ensuring easy access to raw materials. Meanwhile, the choice of equipment and manufacturing techniques plays a decisive role in shaping the final quality of the manufactured sand.

Taking granite‑based manufactured sand production as an example, the process involves three stages of crushing—coarse crushing, intermediate‑fine crushing, and sand making—with the crushing stage primarily utilizing European‑style jaw crushers, single‑cylinder hydraulic cone crushers, and sand‑making machines.

The European‑style jaw crusher is the preferred equipment for coarse crushing, capable of breaking large‑size materials. It can handle most types of rock and offers robust reliability.

Single-cylinder hydraulic cone crushers can crush a wide range of rocks, from medium hardness to harder grades. They offer numerous performance advantages, including a high crushing ratio, high efficiency, low energy consumption, and uniform product particle size. The main types include single-cylinder hydraulic cone crushers and multi-cylinder hydraulic cone crushers.

At present, the most widely used sand-making machine is the vertical shaft impact crusher. It boasts high production efficiency, low energy consumption, excellent particle shape, and relatively low operating costs.

Equipment selection must take into account factors such as the characteristics of the parent rock, production capacity, and finished-product requirements. It also requires consideration of site operating conditions, relevant permitting processes, and compliance with environmental standards—altogether involving dozens of critical factors, making it a highly systematic undertaking. If any aspect is overlooked, it could jeopardize future operations; therefore, choosing the right equipment manufacturer is of paramount importance.
