How is Conductive Carbon Black Powder Manufactured in Industrial Grinding Mills?

Conductive carbon black powder is a critical material used in batteries, coatings, plastics, and electronics due to its excellent electrical conductivity and reinforcing properties. The manufacturing process involves precise grinding of carbon black aggregates into ultrafine particles, a task that demands advanced industrial grinding mills. Here’s a breakdown of the process and the machinery that makes it possible.

The Grinding Process: From Raw Material to Fine Powder

Raw carbon black, typically sourced from petroleum or natural gas pyrolysis, arrives as coarse aggregates. To transform it into conductive powder, the material undergoes several stages:

  1. Pre-Crushing: Large carbon black chunks are reduced to smaller particles (0–20 mm) using jaw crushers or hammer mills.
  2. Grinding: The pre-crushed material is fed into industrial grinding mills, where rollers and rings pulverize it into fine powder.
  3. Classification: A built-in separator ensures particles meet the target fineness (e.g., 325–2500 meshes). Oversized particles are recycled for regrinding.
  4. Dust Collection: Advanced pulse dust collectors capture airborne particles, ensuring a clean production environment.

Key Equipment: MW Ultrafine Grinding Mill
