Description
Grinding ball 40 mm silicon nitride is a ceramic milling medium for laboratory ball mills and planetary mills. With a diameter of 40 mm and silicon nitride (Si3N4) construction, it offers extremely good abrasion resistance and is intended for abrasive sample materials as well as iron-free grinding where metallic contamination must be avoided. For a 500 ml grinding bowl with a useful grinding-stock volume of 80–225 ml, four balls of 40 mm diameter are recommended to support efficient energy transfer and homogeneous particle size reduction. The single-piece unit has a net weight of 0,1 kg and integrates into standard mill accessory sets used in analytical sample preparation. Hard, wear-stable ceramic surfaces help maintain clean processing conditions when hard or abrasive matrices are comminuted. Material guidance is provided via the manufacturer’s reference analyses; this grinding ball from Fritsch suits research and quality-control laboratories that need reproducible milling without introducing iron into the sample stream.
This article is part of Mills, grinders & homogenisers, in Test sieves & mills.

Questions about grinding ball 40 mm silicon nitride
What is this article?
grinding ball 40 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 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.
