Get PriceFeb 18, 2020 Ball-Nose End Mills. Ball-nose end mills have a dome-shaped tip. These excel at high-detail contours like relief artwork or mold and die making, but have what is known as “scalloping.” Since the tip of the end mill is round, having a perfectly flat surface is a challenging feat and will take many more passes than a simple fishtail to smooth
Get PriceBall mills, as the name implies, utilize a larger charge of steel balls (30%) of differing sizes to grind the ore. These mills are smaller in diameter and generally have a length 1.5 to 2.5 times their diameter. Rod mills are used, which are less commonly employed, use carbon steel rods as the grinding media
Get PriceThe ball mill is the fine grinding machine connect the SAG or AG mill and flotation machine. Ball mills produce fine particles with a uniform size for flotation, its grinding medias commonly are steel ball. The ball mill rolls grinding media together with the ore, as the ore grinds, these balls initially 5-10 cm in diameter but gradually wear out
