Pneumatic conveying solution for expanded pellets
During transportation, expanded pellets are prone to breaking, moisture absorption, and clumping. Traditional mechanical conveying methods not only wear equipment but also frequently cause production line shutdowns due to frequent blockages. At the same time, irregular particle shapes and light bulk capacity make manual handling and traditional belt conveying inefficient, and dust emissions affect the workshop environment and operator health.
Material characteristics

Expanded granules are lightweight, porous, have rough surfaces, and poor flowability. Particle sizes typically range from 1 to 10 mm, with low bulk density (about 0.1 to 0.5 g/cm³), making them sensitive to collisions and compression during conveying. Some materials also contain common grease or moisture, which can easily cause pipe adhesion.
Product Introduction

The pneumatic conveying system for expanded particles provided by Head Powder uses sealed pipeline negative or positive pressure conveying technology, customizing core components such as sending tanks, rotary feeders, and dust separators according to material characteristics. The system is powered by compressed air, achieving fully automated, dust-free transfer from the feeding port to the packaging line or storage bin, reducing manual intervention and lowering the damage rate.
Product advantages

To address the pain points of crushing and blockage, the system is equipped with a low-speed, low-shear feeding device, combined with a bend wear compensation design and anti-adhesion coating, effectively controlling the particle damage rate to below 2%. Intelligent differential pressure monitoring and automatic purging function are used to prevent pipeline buildup. The equipment has excellent sealing and, together with filters, achieves dust emissions below 10mg/m³, solving the dust problem in workshops. The modular design supports flexible expansion according to capacity and offers customized solutions to meet the conveying needs of different puffed pellets (such as puffed corn, soybeans, starch, etc.).
