If you’re in need of grinding media, look to Norstone Inc. for comprehensive solutions for grinding, deburring, polishing, or otherwise manipulating materials for industrial and enterprise purposes. The key is to think about the specific functionality of different types of grinding media to get the products you need for specific processes, and to make sure that what you buy will help you to get results over a long period of time.
Ceramic grinding media is another type of item that can help with particle size reduction or provide smooth surfaces and finished, polished results. Ceramics such as alumina, steatite, mullite, zirconia, tungsten carbide and silicon nitride can also be rather durable and less expensive to produce than some other types of grinding media. Zirconias are more expensive but last the longest and are stabilized with magnesium, Yttria or ceria. Many are available in various shapes such as balls, satellites, cylinders, rods and naturals.
Nylon, Polyurethane, and Synthetic Grinding Media
One way to accomplish different processing goals is to go with certain types of synthetic materials. Look at density and size for polystyrene, polyurethane, polycarbonate, or nylon balls or cylinders. These synthetics make a good grinding media because they do not wear the equipment. As a polishing media It may also be helpful to look at how well some of these synthetics will stand up to pressure and still remain gentle.
Different types of silicates are also another choice for grinding media. A variety of bead sizes and formulations provides versatility. Natural silicates such as sand are available as well as various forms of glass and zirconia silicates.
