Yttrium Stabilized Zirconium Oxide Ceramic Grinding Media Balls

Overview

      Highly polished Yttrium stabilized zirconium oxide balls, 60 times the hardness of regular steel, highly wear-resistant and resistant to acid and solvents. Different sizes of zirconium oxide grinding balls available: 3mm, 5mm, 10mm, 15mm, 20mm etc. The grinding media balls are extensively applied to in the fields of Paint, Ink, Geology, Metallurgy, Electronics, Construction Material, Ceramics, Chemical Engineering, Light Industry, Medicine, Environmental Protection and so on.

Features

1. High cost-effective, low wear and long lifetime

2. High specific gravity, high efficiency

3. Highly wear resistant to acid and solvents

4. Highly polished, smooth, easy to clean, low abrasion to the equipment

5. High mechanical strength, good toughness, impact resistance, no broken beads

6. Mainly used for lab planetary ball mill machine

Number and Size of the Balls

1. Pregrinding the coarse, hard material with large balls

2. Use of many small balls will increase the fine fraction if the running time is increased

3. A higher mass (spec. weight) of the grinding balls will accelerate the grinding

4. Size of the Grinding Balls

Type of feed material

Ball diameter

Hard samples feed particle size <10 mm

30 mm or 40 mm

Medium piece size (<5 mm)

20 mm

Fine material (0.5 mm)

10 mm or 5 mm

Homogenisation of dry or liquid samples

10 mm

Homogenisation of viscous samples

20 mm

These are just clues: the size of grinding jars and grinding balls should be determined experimentally if necessary.
