Alumina grinding balls are made of alumina powder as raw material through batching, grinding, powdering (pulping, mud making), molding, drying, firing and other processes. The alumina content of high-aluminum grinding balls is above 92%, and the appearance is white spherical with a diameter of 1-100mm. They are widely used as grinding media.
The grinding media are simply filled from above into the process chamber. In the operating position, we guarantee a homogeneous distribution of grinding media in the grinding container. At the right angle of inclination, the service position allows the uncomplicated and residue-free discharge of …
During comminution in stirred media mills, particles are captured and broken between grinding media or between grinding media and the grinding chamber wall or rotor. The number of grinding media collisions is, therefore, one of the key indicators of the grinding progress [ 32 ].

· Cast iron grinding media – for the production this type of the grinding media used cast iron as "gray" and "white." The ceramic grinding media – this type of the grinding media, as the name suggests, is made of ceramic and used mainly in small-sized mills (about 50 …
· Grinding media diameters with the number of beads per liter at 87% filling load are listed in Table 1. The exponential increase in beads or contacting points as the diameter is reduced gives evidence to higher milling efficiencies. Figure 3 depicts the effects of media size on grinding times.
Material is introduced into a milling chamber in which grinding (milling) media are contained. Milling occurs when the media is made to move either by stirring (using a rotor) or by shaking/vibrating the chamber and contacts the bulk material thus imparting, depending on the milling parameters, either impact or shear forces on it.
