Description
Grinding ball 15 mm silicon nitride is a durable milling medium made from silicon nitride (Si3N4) for laboratory ball mills. The material offers extremely good abrasion resistance and is intended for abrasive samples as well as iron-free grinding, helping to limit metallic contamination of the sample. With a diameter of 15 mm, the ball suits common grinding bowl volumes used in planetary and similar mill systems. Manufacturer guidance indicates typical loadings of about 70 balls in a 500 ml bowl, 45 in 250 ml, 10 in 80 ml and 7 in 45 ml bowls, aligned with useful sample fills in those vessels. Detail material data are referenced via the supplier’s guide analyses. Supplied as a single piece with a net weight of 0,0050 kg, this grinding ball from manufacturer Fritsch supports reproducible sample preparation where hard, wear-resistant media and iron-free processing are required in analytical and materials laboratories.
This article is part of Mills, grinders & homogenisers, in Test sieves & mills.

Questions about grinding ball 15 mm silicon nitride
What is this article?
grinding ball 15 mm silicon nitride is the article on this page. Luminix Health distributes Fritsch for laboratory use. It sits in Mills, grinders & homogenisers, inside Test sieves & mills, in Instruments de laboratoire.
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 Instruments de laboratoire.
Shelves beside this one are Test sieves (wire mesh), Test sieves (perforated plate), Sieve shakers and Sieve accessories (lids, pans, rings).
What should I check before I order?
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
