Graphite is used for numerous applications including batteries, refractories, and numerous other high end electronic applications. Graphite powder is extremely light weight and this can make screening it very difficult. Furthermore, graphite particles are often mis shaped and angular which can cause the appearance of oversized material in the product stream when testing with a laser.

Elcan's Experience

Elcan Industries has done extensive work with graphite powder using both our Minox and Hi-Sifter systems. For graphite that has needle shaped particles, we have developed a system using the Minox System with balls to prevent these needles from ending up in the product. On the Hi-Sifter, Elcan has proven capable of screening graphite powder down to 20 microns with a 98% efficiency.
