What is Carbon Black Powder? Carbon Black Powder is a material that is a by product of the combustion of heavy petroleum powders. Carbon Black Powder is sometimes used in the batteries to replace the use of Graphite as the battery anode material in the product. Carbon Black for battery applications needs to be sized to a very tight range in order to function at its full potential. Sieving Carbon Black is a difficult process due to the low density of the product and lack of flow-ability. To sieve Carbon Black efficiently, high acceleration energy on the screen surface is needed to keep the material from blinding the screen and overwhelming the screen mesh.
Contract Manufacturing Experience
Elcan has sieved carbon black powder at sizes as fine as 32 microns. Using a double deck screener, Elcan often helps companies meet both the top and bottom size specifications of their carbon black powders. Regardless of how tight the spec is, Elcan has consistently achieved success classifying carbon black with precision. The high energy on the screen surface keeps particles elevated and prevents blinding—one of the most critical factors in maintaining a consistent size distribution output.
In addition to sieving, Elcan also offers electromagnetic separation of carbon black powders to remove fine metallic contamination. Using our UL-rated, high-intensity electromagnetic separator, we can extract embedded iron and steel particles that often go undetected by traditional magnetic systems—ensuring a cleaner final product for high-purity applications.
