Description
Grinding ball 50 mm sintered corundum-1 is a ceramic milling medium based on sintered corundum (Al2O3) for laboratory grinding applications. Measuring 50 mm in diameter, it offers conditionally good abrasion resistance and is specified for medium-hard as well as fibrous sample materials processed in vibratory and high-speed mills. The dense oxide ceramic supports effective particle-size reduction while maintaining mechanical stability under typical laboratory milling conditions. Delivered as one piece with a net weight of 0,300 kg, the ball fits standard grinding assemblies used in analytical and materials-preparation laboratories. Further compositional guidance is available via the manufacturer’s reference analyses. This sintered-corundum grade from manufacturer Fritsch provides a practical option when medium-hard or fibrous matrices must be processed reproducibly. It belongs to the accessory range for vibratory mills and rapid mills, enabling consistent sample preparation for subsequent analytical steps without introducing unnecessary process complexity.
This article is part of Mills, grinders & homogenisers, in Test sieves & mills.

Questions about grinding ball 50 mm sintered corundum-1
What is this article?
grinding ball 50 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 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?
