We focus on the R&D of Jiulongbi stone’s industrial applications, especially stone rollers, which are high-performance belt conveyor rollers for bulk material handling. As new type of conveyor rollers, we leverage Jiulongbi Stone’s inherent advantages, such as high hardness, corrosion and rust resistance, bending resistance, and strong load-bearing capacity to replace traditional metal components. With our patented double-layer sealing technology, the stone rollers effectively address the industry challenge of short service life faced by metal rollers in dusty and highly corrosive environments, providing a new and reliable solution for the belt conveyor industry. This development is recognized as the fifth major innovation in the roller sector.
