Grinding Media Balls

We are manufacturer of hyper steel and high-chrome steel grinding media in various alloy compositions and sizes. Grinding media are used in ball mills to grind the material to required fineness. Grinding media is available in various hardness ranges for different application, in both high carbon steel and chrome alloy steel. Grinding media are always consumed in a large quantity, cost and wear rate become the most important aspect to choose the size and quality. We are manufacturing cost effective grinding media for many years and are now able to provide grinding media with very low wear rate in the market. We manufacture grinding media in various sizes and shapes to suit different needs. Our time tested heat treating processes gives a much better durability. We also develop custom made grinding media as per the needs of customer.
