Beschreibung
Grinding ball 20 mm hardened stainless steel is laboratory milling media designed for hard, medium-hard and brittle sample materials in ball-mill workflows. The hardened stainless-steel construction provides good abrasion resistance for everyday grinding tasks where extreme hard-metal media are not required. At 20 mm diameter the ball matches common bowl geometries used in planetary and related laboratory mills. Recommended fillings are 25 balls for a 500 ml grinding bowl (useful sample volume 80–225 ml), 15 balls for a 250 ml bowl (30–125 ml), and 5 balls for an 80 ml bowl (10–30 ml), supporting balanced milling efficiency and controlled wear. Supplied as a single piece with a net weight of 0,03 kg, the media piece is suitable for routine sample comminution and homogenisation in analytical and materials laboratories. The product comes from manufacturer Fritsch and aligns with standard accessory sets for grinding bowls of the stated volumes. Material reference data from the manufacturer support selection against sample hardness and process requirements.
This article is part of Mills, grinders & homogenisers, in Test sieves & mills.

Questions about grinding ball 20 mm hardened, stainless steel
What is this article?
grinding ball 20 mm hardened, stainless steel is the article on this page. Luminix Health distributes Fritsch for laboratory use. It sits in Mills, grinders & homogenisers, inside Test sieves & mills, in Präzisionsinstrumente.
A mill, grinder or homogeniser reduces particle size or breaks a tissue before an extraction. The rotor and the sieve insert decide the result. A knife mill and a bead mill are different machines. The sample has to tolerate the heat the motor puts into it.
A test sieve sorts particles by whether they pass an opening. Wire mesh and perforated plate are two ways of making that opening, and the nominal size is not a suggestion. A sieve shaker repeats the motion so the result does not depend on how hard someone shook by hand. A mill or grinder makes the particles smaller before they are sieved. The certificate of the sieve, and the opening size, are what an audit asks for. Measurement practice around mass and dimension sits with the BIPM, EURAMET and BELAC.
Which category should I open next?
The category is Test sieves & mills. The sub-category is Mills, grinders & homogenisers. The catalogue is Präzisionsinstrumente.
