Milling and grinding media are designed for ball milling and the grinding of bulk powder or granular materials into finer powder forms. Ceramic bead, hard metal shot, carbide balls, and other ball-shaped media are used. The hardness of the powder or bulk material to grind determines the selection of the media material. Ball milling processes can disperse or mix pigments or fillers into resins, paints, coatings, plastics, rubber or adhesives.Media grinding is also used to mechanically alloy metal powders, permitting the creation of substances that cannot be formed through other processes. Ball milling media consists of wet, batch units in which water or other liquids and additives aid the grinding process by reducing friction and providing cooling. Ball grinding media uses an abrasive bonded to a wheel, belt, or disc to remove material and improve surface finish. Media mills are also used to disperse powder into a liquid product such as pigment in a paint base.
There are many types of milling and grinding media. Examples include alumina grinding media and chrome grinding media. Alumina grinding media is high-density, and ultra-high fired. It is ideal for wet or dry milling. Chrome grinding media is a high density, very hard product suitable for grinding and milling. Alumina grinding media and chrome grinding media are non-conductive, non-magnetic, tough, hard, non-porous, chip resistant, and easy to clean. Alumina grinding media and chrome grinding media are unaffected by most acids or alkali. They have excellent resistance to mechanical and thermal shock. Ball milling and grinding media can also use hardened steel balls (shots, beads) which are available in different hardnesses in both high-carbon steel and chrome alloy steel. Linear ball mill grinding uses a linear model of balance and substitution for the real distribution for the time of grain processing inside the mill, which is a combination of ideal extrusion and ideal mixing.

The grinding ball is a material grinding media of ball mill and coal mill. Its' function is as an important component of ball mill under grinding and cutting effect brought by the friction between grinding balls and materials.Therefore,let's talk about the processes of matching the proper grinding balls for ball grinder.
1. With effective surface area of steel balls to measure the rationality of the steel ball ratio. A warehouse in effective surface area of steel balls should achieve every ton of steel balls 9.5-10.5 m2. For with the roller press of closed circuit ball mill, this value can be adjusted for 12 m2/t, and the liner plate is continuous ascension type. The balls in the specific surface area should be 35-38 m2/t, belt roller pressure unit for 38-40 m2/t. The ratio of specific various balls diameter still according to the maximum stacking density calculation.
2.Generally, the load rate is 25% -35% in the filling space of abrasion resistance steel balls, the lower loading rate of steel ball, the less of power consumption, and the productivity is getting low. Therefore, the primary prerequisite of the total count of adding grinding media is that the ball weight and the weight of the material in the mills is less than the allowable value and close to the ball mill motor power.
3. Conforming to the loading principle on grinding balls in the main warehouse. The size of feeding clinker particle in the first warehouse is not more than 30 mm, so it's main function is broken, and the diameter of Steel balls loaded should be in 50 between 90 mm. When into the second warehouse of ball grinding mill, the clinker are less than 2-3 mm, so it is the function of fine grinding, steel balls' range in this warehouse should be 15-50 mm.
4. Computing unit ball production to verify the rationality of the match ball.
5. Determining the maximum diameter of the grinding media.
