Overview

      Austenitic stainless steel balls, they can be provided in the annealed, cold worked, hardened, magnetic or not magnetic state. The stainless steel grinding balls are extensively applied to in the fields of Metallurgy, Electronics, Construction Material, Ceramics, Chemical Engineering, Light Industry, Medicine, Environmental Protection, Paint, Ink, Geology and so on.

Features

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

2. High specific gravity, high efficiency

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

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

5. 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.
