• Ultra-Fine Grinding & Particle Size Reduction Services (0

    Capable of ultra-fine grinding dry powders to 0.5-45-micron averages, our Micro-Jet horizontally oriented jet mill generates a maximum amount of “fines,” for customers who require high surface areas for their fine powder applications.How do you melt silver plated items and get solid silver,May 01, 2013· That's not quite true. Actually what you would find is a base metal, probably steel, plated with a 6 mill (0.006 inch) thickness of Nickel. Silver won't stick to steel but it will stick to Nickel. Then over that is probably 25 to 50 microns of Silver. One micron is One Millionth of an inch, or 0.000001 inch.
