Grinding balls / Polishing balls
Grinding balls can be manufactured from various materials, including steel, aluminum, ceramic, glass, etc. A wide variety of manufacturing materials can meet different tasks and needs. For example, ceramic grinding balls are often used in food processing, while steel balls are often used in heavy industrial situations.
Grinding balls are often mass-produced and sold in kilograms. There is no precise requirement for their accuracy. Still, they must be reliable and wear-resistant to suit different industrial needs, such as hardness, surface, cleanliness, etc. Grinding balls can be customized for any task that requires grinding.

Applications: Grinding different mixtures (concrete, food, etc.), ball mills, roll, and vibration finishing, polishing, shot peening, and filtration systems. They are often used as packing or cover elements in electrical, hydraulic, or thermal applications. Examples include processing grain in food production systems, working concrete to the desired consistency, or in shot peening equipment for strengthening automobile crankshafts.
Choosing the right media for grinding and milling operations is crucial. Grinding media are used to grind or crush the material to reduce particle size and refine the material. Grinding media come in a wide variety of materials, shapes, and sizes. Which media is appropriate depends on the context of the intended application. The properties affect how the material is processed and the duration of the medium.
