Ball mill alumina grinding media

Short Description:

Alumina grinding balls are widely used in ball mills as abrasive media for ceramic raw materials and glaze materials. Ceramic, cement and enamel factories as well as glasswork plants use them because of their excellence of high density, their high hardness, and their high wear resistance. During the abrasive/grinding processing, ceramic balls will rarely be broken and the contamination factor is minimal.

This alumina grinding media possesses excellent thermal properties. So you can grind down to the particle size you need to achieve.
Better for some applications than porcelain, flint pebbles, or natural stones, Yiho Alumina grinding balls are precisely engineered, down to the nanometer.
Because when it comes to your ball milling process, every nanometer counts.

Advantages of Alumina (Al2O3) Grinding Balls

High performance wear resistant alumina ceramic balls are used in grinding and milling various materials.

Different sizes of alumina grinding balls are available: <1mm, 1.5mm, 2mm, 2.5mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 13mm, 15mm, 20mm, 30mm, 40mm, 50mm. 60mm

The alumina grinding / milling media balls are extensively used in the fields of Paints, Inks, Geology, Metallurgy, Electronics, Ceramics, Glass, Refractory, Chemical Engineering, etc

Additional Information on Alumina Milling Media Balls

Pre-grinding the coarse, hard materials with large balls
The use of many small balls will increase the fine portion of the materials when the grinding time is increased
A higher percentage of the grinding balls will accelerate the grinding process

Choice of Grinding Jars & Grinding Balls
In order to prevent excessive wear abrasion, the hardness of the grinding jars and the grinding balls must be higher than that of the material used for grinding. Normally, grinding jars and grinding balls of the same material should be chosen.
These are general recommendations: the size of grinding jars and grinding balls should be determined experimentally if necessary.
