Properties of Alumina Milling Balls

 

High purity aluminum grinding balls and grinding columns can be used as grinding media for various grinding equipment, especially fine grinding equipment, including ball grinder, pot grinder, vibration grinder, etc. thanks to its features as follow:

⩟ With characteristics of high hardness, high strength and low wear, therefore they have no effect on the quality of grinding materials, and the problem of polluting raw materials by grinding media is solved.

Compared with normal alumina grinding medias, high purity alumina grinding ball and cylinder has large density, which can greatly improve the grinding efficiency, reduce the grinding time:

The wear resistance is good, so can greatly extend the service life of the grinding media.

The density is less than half of the steel ball, which can reduce the noise and power consumption of the grinding equipment, and reduce over-grinding under fine grinding conditions, saving grinding time and power consumption.

With high temperature resistance, corrosion resistance, they are suitable for all kinds of grinding materials.
