Generally, filling the mill by balls must not exceed 30%–35% of its volume. The productivity of ball mills depends on the drum diameter and the relation of ∫ drum
The high impact of conventional ball mills is not needed in vibro mils. Instead a large number of low energy impacts are necessary using small grinding media with high vibration or rotation rate. Recommended grinding media : Cylinders of 6.0 mm to 20.0 mm. Recommended media charge : 60 - 70% of mill’s useful vol. Calculation of media load
Rate of ceramic body grinding in a ball mill 191 product applicability. This is related to the use of ground product in the production of ceramic materials that should satisfy strictly specified users’ demands. In production technology of ceramic floor tiles an increased contribution of
Advantages and features of the ceramic ball mill. The grinding fineness depends on the milling time. The motor of the ceramic ball mill is started by the coupling reduce voltage which lowers the starting electricity and the ball mill’s structure is divided into integral type and freestanding type; advantages of the ceramic ball mill are lower investment, energy saving, structure novelty
