Fine Mesh Powder Screening Solutions In Motion

On Size Sieving is a problem that occurs when the actual particle that should pass through your sieve or screen is just a hair too big or too small for the screen you’re using. For example, the lab is indicating that your sieve analysis shows 70% of your powder is passing through a 53 micron sieve (270 mesh) but you can only achieve 45% passing through the 270 mesh in production.

Powder Metallurgy For Manufacturing

A powder sample is poured on the top screen. A machine vibrates the stack. Powder particles will fall through the screen openings until they encounter a screen size too small to fit through. Thus, each screen will collect metal powder particles of a certain size range. The sizes and distribution of sizes can then be measured.

Shotting: Fine stream of molten metal is poured through a vibratory screen into air or protective gas medium. When the molten metals falls through screen, it disintegrates and solidifies as spherical particles. These particles get oxidized. The particles thus obtained depends on pore size of screen, temperature, gas used, frequency of vibration.
