The main feed barrel serves as the primary material entry point, operating under starved feeding conditions to establish stable and continuous material intake.

Its large-volume inlet geometry is optimized based on bulk density and material flow characteristics, ensuring efficient feeding of pellets, powders and additives without bridging or accumulation.

Integrated cooling channels prevent premature softening or sticking of materials at the feeding interface, maintaining a dry and free-flowing intake environment. Wear-resistant bimetallic liners ensure durability under high-throughput abrasive conditions, forming the foundation for stable downstream melting and conveying.

Key Features

Optimized feed port geometry

Supports pellet and powder feeding

Ensures consistent fill level

Design & Technical Insights

Feed barrels operate under starved feeding conditions, requiring precise inlet geometry to maintain stable and consistent material flow.

Improper matching between feed design and material behavior can result in bridging, feed fluctuation or unstable throughput, directly impacting downstream melting and pressure stability.

Improper design can lead to bridging or inconsistent throughput.
