Powder processing often involves bulk powders, additives, or ingredients being milled for particle size reduction. A mill or grinder uses a mechanical action to break the material and reduce it to the required size. This may encompass a whole range of requirements from de-agglomeration and coarse grinding through to fine grinding and classifying.

Re-grinding can produce uneven particle sizes, leading to inconsistent extraction and poor flavor. Plus, it can overheat the coffee, affecting its taste. ...

 — A comprehensive analysis reveals that the post-grinding coffee particles primarily fall within the [20 μm, 1500 μm] range. Moreover, as the blade setting escalates, the cumulative particle size distribution curve for sizes above 100 μm demonstrates a shift towards larger particle sizes. ... analysis. In Fig. 16, each scatter point represents ...

 — Because the grinder has big and aggressive 48 mm steel burrs, it's also an incredibly speedy grinder. It's much faster than typical manual grinders with ceramic burrs that you might be familiar with. ... it's …

When fines are attached to bigger particles, they act as part of the large particle in the extraction and do not over-extract as when they are separate where fines only stick to other fines. ... Independently we found that grind from a bulk grinder (big burrs and high speed; grams per minute) tasted better after reducing visible fines. Less ...

These general purpose three-phase 200 to 480V sewage grinder pumps have three-phase motors that are more efficient than one phase, and they use a higher voltage that allows for larger motors that require less current than lower-voltage motors. Pumps shred large particles into small fragments so the waste can be pumped into a sewage system.
