Carbon Black Pellets and Powder
Amorphous Carbon (C) · Furnace Black · Channel Black · Thermal Black · Acetylene Black
Carbon black is a fine, black powder or pelletized material composed primarily of elemental carbon. It is produced by the incomplete combustion or thermal decomposition of hydrocarbons. In powder form, it is extremely lightweight, cohesive, and dusty, posing explosion and health hazards. Pelletized carbon black reduces dusting but can still generate fines during handling. KWS designs conveying systems that provide dust containment, explosion protection, and gentle handling to prevent degradation.

Material Characteristics
| Property | Value / Description |
|---|---|
| Common Forms | Powder, Pelletized Solid |
| Bulk Density | 20–40 lb/ft³ for pellets; 10–15 lb/ft³ for powder |
| Flow Behavior | Cohesive and aeratable; prone to flooding or flushing |
| Abrasiveness | Low minimal wear on equipment surfaces |
| Corrosiveness | Not Corrosive but stains and contaminates surfaces |
| Dust Potential | High fine carbon particles are combustible and must be contained |
Handling Challenges
- Severe dusting and explosion risk in powder form
- Caking, bridging, and buildup in conveying equipment
- Airborne dust causing staining and environmental concerns
- Pellet degradation producing fines and dust carryover
- Need for inert gas or explosion suppression in certain systems
Summary
Carbon black pellets and powder require conveying systems designed for dust control, explosion protection, and gentle material handling. KWS Manufacturing provides engineered solutions—including enclosed screw conveyors, tubular drag conveyors, and feeders—that prevent dust emissions and material degradation.
With extensive experience handling fine, light, and hazardous materials, KWS ensures safe, efficient, and reliable operation in carbon black processing and handling applications.
