Mills, grinders & homogenisers

A jaw crusher pre-crushes coarse, hard material. A rotor mill grinds soft to medium-hard samples quickly. A cutting mill handles fibrous, soft or moist material, such as plants and food. A ball mill or planetary mill grinds finest, down to the micrometre range. Several mills in sequence can give a better result for hard, coarse samples. Check the result with a test sieve; see test sieves and sieve shakers. Unsure which one fits? Ask sales@luminixhealth.com.

Choose a material that is harder than your sample and contains no elements that would interfere with your analysis. Options include agate, zirconium oxide, tungsten carbide for very hard samples, hardened or stainless steel, and sintered corundum. For metal-free analysis, avoid steel, because abrasion would contaminate the sample. Clean the jar thoroughly between samples. Check the materials on the product page in mills, grinders and homogenisers. Need advice for your set-up? Mail sales@luminixhealth.com.

Use larger balls for coarser feed material and smaller balls for a finer end result. The filling recommendation, meaning the number of balls per jar volume, is given in the manual of your mill or on the product page. Preferably choose balls and jar in the same material, so wear does not add a second contaminant. Do not overfill the jar. Balls and jars are in mills, grinders and homogenisers.

A rotor-stator homogeniser works in liquid: it suits soft tissue, suspensions and emulsions, which it breaks up and disperses. A mill is for dry, solid materials that need to be reduced to powder. Some samples need both, first grinding and then dispersing in a solvent. For fine manual work, a mortar and pestle can be enough. Cool heat-sensitive samples during processing. See homogenisers and dispersers. Questions about a specific product? Contact sales@luminixhealth.com.

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.
