River pebbles are hard, wear-resistant and have good particle shape, which is an ideal raw material for high-quality machine-made sand. In Thailand, where natural sand resources are scarce, a 150TPH river pebble sand making line has been put into operation, providing high-quality machine-made sand for local construction projects and solving the problem of raw material shortage.
### Project Basic Information
Project Location: Bangkok, Thailand
Processing Material: River pebbles (Mohs hardness 6-7, low mud content, no impurities)
Production Capacity: 150TPH (daily output 3,600 tons)
Finished Products: 0-5mm machine-made sand (for commercial concrete and high-rise building construction)
Process Flow: Primary crushing → shaping → screening → washing
### Equipment Configuration & Process Advantages
The production line adopts a "primary crushing + shaping + screening + washing" process to ensure the quality of machine-made sand. Primary crushing uses a small jaw crusher to crush large river pebbles (≤400mm) into ≤50mm particles. 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, with a fineness modulus of 2.6-3.0.
The screening stage uses a 2-layer vibrating screen to separate machine-made sand and unqualified materials (return to shaping for reprocessing). The washing stage uses a sand washing machine to remove impurities such as dust and fine mud in machine-made sand, ensuring that the mud content of finished sand is ≤1%, which meets the Thai commercial concrete standard.
### Operation Effect
Since its commissioning, the production line has operated stably with a failure rate of ≤1.5%. The machine-made sand has good particle shape, high strength and stable quality, which is widely used in local high-rise building construction and bridge projects. The project has an annual output value of about 1.2 million US dollars, and the investment can be recovered within 1.5 years.
