Description
Grinding ball 20 mm hard metal tungsten carbide is a precision milling media component for laboratory ball mills used with hard and abrasive sample materials. The ball is manufactured from tungsten carbide WC-GC10, a dense hard-metal grade selected for very good abrasion resistance during intensive grinding. With a diameter of 20 mm it suits standard grinding bowls in planetary and similar mill systems. Recommended loadings are 25 balls in a 500 ml bowl (useful sample volume 80–225 ml), 15 balls in a 250 ml bowl (30–125 ml), and 5 balls in an 80 ml bowl (10–30 ml). These ratios help maintain efficient energy transfer while protecting bowl and media life. The component is offered as a single piece with a net weight of 0,07 kg and is intended for routine sample preparation of hard, abrasive solids. Supplied from manufacturer Fritsch, the ball integrates into established laboratory milling workflows where tungsten carbide media are preferred for wear performance and process consistency. Detail material guidance is available via the manufacturer’s reference analyses for the WC-GC10 grade.

Questions about grinding ball 20 mm hardmetal tungsten carbide
What is this article?
grinding ball 20 mm hardmetal tungsten carbide is the article on this page. Luminix Health distributes Fritsch for laboratory use. It sits in Mills, grinders & homogenisers, inside Test sieves & mills, in Lab instruments.
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 Lab instruments.
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.
