Powder Fineness (Types of Powder) : Pharmaceutical Guidelines

Superfine powder A powder of which not less than 90 percent by the number of the particles are less than 10 micron size. When the fineness of the powder is described by means of a number, it is intended that all the particles of the powder shall pass through a sieve of which the nominal mesh aperture, in /lill, is equal to that number.

Powder Milling an overview ScienceDirect Topics

Powder metallurgical processing of MMC (see Chapter 3.25 this volume) sharply reduces the danger of interfacial reaction occurring. Any MMC scrap (discontinuously or continuously reinforced, and irrespective of reinforcement content) can be milled to powder (or machined to chips). This may serve as raw material for secondary MMC-powder

After passing the sieve ring the milled powder has to be separated from the accompanying air. The degree of fineness achieved will depend on the nature of product, type rotor and the sieve ring fitted. It is also influenced by rate of feed, the quantity of air sucked into the mill with the feed and the peripheral speed of the rotor.

What are the Differences Between Dry and Wet Type Ball

Mar 10, 2021 The dry milling process may be used when the particle size of the powder is not required to be very fine or when the ball milled product is to be stored or sold in powder form. For example, in the production of cement, it is necessary to choose dry grinding instead of wet grinding, otherwise, it will be difficult to meet our needs. 2.
