Compared to the other normal ceramic grinding media, the main improvement of UG2 Ceramic Grinding Media is the double-performance of wear-resistance. Based on special formula design, UG2 also has much better impact resistance. With UG2 ceramic beads, the contamination from the grinding media into final product can be much reduced. UG2 is the best choice for Nano- size materials milling application. It saves the milling process cost and improve the materials purity at same time.
