Alumina Ceramic Grinding Media
Product Description
This Alumina Ceramic Grinding Media is suitable for wet and dry
ultra-fine grinding of alumina, zirconia silicate, feldspar,
quartz, kaolin, glaze, ink, ceramics and so on in stirring and ball
mill. It comes in different forms such as alumina oxide balls,
ceramic cylinders, or soda lime glass. The grinding media is made
of selected first-class raw materials with static pressure forming
technology by high temperature firing. Alumina Ceramic Grinding
Media can greatly improve grinding efficiency, reduce grinding
time, and effectively increase the volume of the ball mill, thus
increasing the amount of grinding materials.
Advantages
This Alumina Ceramic Grinding Media is used for grinding or
separation of non-metallic mineral powder and coating materials, as
well as polishing metal parts. It is suitable for all kinds of
grinding and polishing machines. It increase the wear coefficient
when added to rubber. This alumina grinding media possesses
excellent thermal properties. So you can grind down to the particle
size you need to achieve. If you are interested, please feel free

Test method of alumina ball
This method means that alumina ball is impacted in specified
condition in polyurethane jar to test shock resistance, wear loss
in unit time.
Grinding jar
The grinding jar in made of polyurethane with inner diameter of
200mm, length of 220mm
Test preparation
Put 4kgs alumina ball with qualified appearance in to the jar with
4L water, then set on the anti-wearing machine at 80rpm for 2
hours, then take out, clean and dried for preparation.
Testing step
· Weight the sample after treatment with balance (M1)
· Put the sample and water with same weight into jar, and set on
the anti-wearing machine at 80rpm for 24 hours.
· Take out the samples, clean, dry and get the new weight(M2)
· Wear loss= (M1-M2)x1000/M1
