Company Profile

SY (SanYuan) company embarked on an ambitious journey into the world of microsilica back in 2001, laying the groundwork for cutting-edge research and promotion of this remarkable material. Beyond the original Yinchuan factory, Gansu Sanyuan proudly unveiled the state-of-the-art 'Lanzhou factory'. It has also
transformed the Yinchuan facility into an exemplar of modern engineering—safer, more technologically advanced, highly efficient, and eco-friendly—thanks to the addition of comprehensive environmental protection systems. Moreover, the upgrade introduced sophisticated screening and classification capabilities. With the strategic addition of the Tianjin Distribution Center, complementing our existing trio of storages in Gansu, Ningxia, and Inner Mongolia, we have realized unparalleled efficiency in quality control and rapid logistics.
For nearly two decades, we have been at the forefront of producing and distributing top-tier microsilica, honing our expertise and gaining invaluable experience in this specialized field. Our impressive annual production capacity exceeds 100,000 tons, firmly establishing Sanyuan as a frontrunner in the microsilica industry.
In China, Sanyuan has been a trailblazer, steering the industry for decades. Our esteemed participation in crafting the national standards for microsilica underscores our commitment to excellence and innovation.
