About SGI

Global Supply Solutions

Sino Grinding International (SGI) is a global company specializing in the design, manufacturing and distribution of grinding media. Our regional marketing offices offer regular on-site technical and logistical support. Our customers benefit from SGI’s proactive product development and site-specific adjustments to meet their milling requirements, and gain the advantage of a supplier who wants to work side-by-side to improve grinding circuit performance. Our metallurgical expertise and grinding media designs are second to none.
Each processing site is unique and requires a custom solution. All of our ball grades are adjustable to meet milling targets. In many cases SGI will work out a transitional strategy with the client to purge existing media and replace it with one of SGI’s premium grades.
