A metallic powder needs to have a mixed particle size range

A metallic powder needs to have a mixed particle size range between 0.0018\" and 0.0015\". If the thickness of the wire is 0.0008\", what would the mesh count on the screens need to be to provide the proper sizes for the mix?

Solution

Mesh Count is the number of openings per unit inch length

Maximum particle size of metallic powder is .0018\"

Hence the opening on mesh is X=.0018\"

The thickness of mesh is T=.0008\"

Mesh count M=1/(thickness+opening)

M=1/(.0008+.0018)

M=384.6

M=385 should be the mesh count on the screen to provide the proper mix
