Description
Grinding ball 15 mm sintered corundum-1 is a ceramic grinding medium intended for laboratory ball mills and related milling systems. Manufactured from sintered corundum-1 based on Al2O3, each ball measures 15 mm in diameter and has a net weight of 0,0070 kg. Abrasion resistance is described as conditionally good, making the media suitable for medium-hard and fibrous sample types where aluminium oxide contact is acceptable. Available as single pieces from manufacturer Fritsch, the balls are matched to common grinding-bowl volumes: recommended loadings are about 70 balls for a 500 ml bowl (useful content 80–225 ml), 45 for 250 ml (30–125 ml), 10 for 80 ml (1–30 ml) and 7 for 45 ml (3–20 ml). Sintered corundum media support efficient size reduction of plant fibres, polymers and other mid-hardness materials prior to further analytical or processing steps. They fit planetary mill workflows that specify 15 mm grinding balls and Al2O3-compatible bowl sets in research and industrial laboratories.

Questions about grinding ball 15 mm sintered corundum-1
What is this article?
grinding ball 15 mm sintered corundum-1 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.
