Saudi Arabia has booming infrastructure construction, and has strict requirements for aggregate quality and environmental protection. A 450TPH tower type aggregate production line in Saudi Arabia has been put into operation, realizing closed, intelligent and green production, providing high-quality aggregate for local high-rise building and highway construction.
### Project Overview
Project Location: Riyadh, Saudi Arabia
Processing Material: Limestone (CaO content ≥53%, low SiO2 content, easy to crush)
Production Capacity: 450TPH (annual output 2.7 million tons)
Finished Products: 5-10mm, 10-20mm, 20-31.5mm aggregate (for high-rise building and highway construction), 0-5mm machine-made sand
Process Flow: Primary crushing → secondary shaping → tertiary screening → aggregate optimization

### Equipment Configuration & Process Advantages
The production line adopts a tower-type integrated design, integrating crushing, shaping, screening, dust removal and intelligent monitoring into one, saving 60% of floor space. Primary crushing uses a large jaw crusher with a maximum feeding size of 500mm, which can efficiently crush large limestone blocks. Secondary shaping uses an impact sand making machine, which adopts the rock-on-rock crushing principle to make the finished product particle shape cubic and uniform.
The screening stage uses 4 sets of 3-layer high-efficiency vibrating screens to separate four specifications of finished products. The aggregate optimization system adjusts the particle size distribution of finished products, improving the quality of aggregate and machine-made sand. The whole line is equipped with a fully enclosed workshop and 30 sets of pulse dust collectors, ensuring that the dust emission concentration is ≤8mg/m³, meeting the strict environmental protection standards of Saudi Arabia.
The intelligent control system realizes one-key start and stop, real-time monitoring of 200+ operation parameters, and automatic generation of maintenance plans, reducing the shutdown rate by 40% and labor cost by 70%.
### Operation Effect
The production line has operated stably for more than 1 year, with an average daily operation time of 22 hours and a failure rate of ≤1%. The finished aggregate and machine-made sand have stable quality, the needle flake content is ≤3%, and the particle size uniformity is ≥95%, which fully meets the Saudi Arabian high-grade aggregate standard. The project has an annual output value of about 3 million US dollars, and the investment return cycle is 1.8 years.
