The percentage of the ratio of the volume filled by the grinding body of the ball mill grinding media to the effective volume of the mill is referred to to a certain extent as the filling rate of the grinding body, and the filling rate of the grinding body has a great influence on the grinding efficiency of the mill. If the filling rate of the grinding body is too high or too low, the grinding efficiency of the mill will be reduced. For grinding machines with a grinding body filling rate greater than 32%, the following empirical formula can be used to directly calculate the filling rate.

When the grinding media of a ball mill is operated, there are many factors that affect its grinding body to a certain extent. Therefore, during the production process, the optimum filling rate is mainly determined through its experiments, and it is based on a certain degree. The degree of change of the influencing factors is adjusted appropriately, and the filling rate of the grinding body of the secondary closed-circuit ball mill and the multi-bin mill should be appropriately adjusted according to the equilibrium state of the grinding action of each level or bin. When the production needs to change the product variety or quality requirements, it should also consider properly adjusting the filling rate of the grinding body.

During the operation of the grinding media of the ball mill, the mass of the grinding body loaded into the grinding wheel is referred to as the grinding body loading to a certain extent. When it is used, it depends mainly on the filling rate of the grinding machine. The loading G of the grinding body can be calculated as follows, where G is the loading volume (t) of the grinding body, V is the effective volume of the mill (m3), Di is the effective diameter of the mill (m), and L is the grinding capacity. The machine effective length (m), φ is the filling rate (%) of the grinding body in the mill, and ρ is the grinding body bulk density (tm3). The ball volume density is generally 4.56~4.85tm3.

Ball mill liners are best made of ceramic lining bricks

The appearance of the grinding media of the ball mill will appear delicate white to a certain extent. During the operation, the two lining bricks are connected with the sub-mothers, so that the connection strength can be ensured to a certain extent, and the main component thereof is high-quality oxidation. Aluminum, high whiteness, does not have any adverse effect on the quality of the material being ground.

The ball mill grinding media will to some extent be due to its excellent wear resistance, to a certain extent

Manganese steel 266 times, mainly as a wear-resistant inner lining of the ball mill, and with high aluminum balls, grinding the slurry delicate. It does not have any adverse effect on the quality of the material to be ground; the rolling and isostatic pressing technology has high density and large specific gravity, which can greatly increase the grinding efficiency, and at the same time increase the effective capacity of the ball mill, thereby increasing the amount of grinding material added; , Acid resistance, alkali resistance, corrosion resistance of the excellent characteristics; is a kind of ultra-low wear ceramic ball, self-wearing only one ten-thousandth of five points, greatly extended the grinding ball life, thereby reducing customer costs.
