PC pellets (polycarbonate pellets) are often broken and dusted due to traditional mechanical conveying methods, which easily absorb static electricity and pollute the workshop environment, leading to increased raw material loss, frequent equipment maintenance, and reduced production continuity. Head Powder offers customized pneumatic conveying systems tailored to the characteristics of PC pellet materials, achieving sealed, low-loss, and stable conveying.

Customer pain points

Traditional hoists or screw conveyors face the following issues when handling PC pellets:

• Material collisions and friction cause particle breakage, increasing the scrap rate;
• Open conveying generates dust, polluting workshop air and affecting employee health;
• PC particles easily generate static adsorption, blocking pipelines or silos;
• Manual handling or simple mechanical conveying is inefficient and cannot meet the demands of continuous production.

Material characteristics

PC particles are thermoplastic engineering plastic pellets, typically 2~5mm in diameter, with a bulk density of about 0.5~0.7 g/cm³. They have a smooth surface, are easily broken, sensitive to temperature, and prone to static electricity generated by friction. During transportation, such materials must avoid high-speed collisions, sharp turns, and metal friction, and pipeline grounding must be explosion-proof.

Product Introduction

The Head Powder PC Pellet Pneumatic Conveying System uses positive pressure dilute phase or dense phase conveying methods, delivering PC particles through compressed air (nitrogen optional) through sealed pipelines to the silo or usage point. The system consists of a feeding device, delivery pipelines, rotary valve or sending tank, dust filter separator, electrical control system, and more. Non-standard customization can be made according to customer factory layout, conveying distance, and capacity requirements, supporting multi-channel sorting, automatic metering, and centralized control.

Product advantages

To address the pain points of fragile PC particles, concerns about static electricity, and dust exposure, Head Powder focuses on the following measures in its plan:

• Low shear force design:Venturi feeding or low-pressure sending tanks are used to reduce the impact of the material acceleration section, with the particle crushing rate controlled within 0.5%;
• Fully sealed and dustproof:Food-grade seals are used at pipeline and equipment connections, preventing dust overflow and meeting environmental protection and clean production requirements;
• Static Discharge and Explosion Protection:Ensure reliable grounding of all pipelines and equipment, and install static elimination devices at key locations to prevent static buildup;
• Intelligent Control:PLC + HMI control enables real-time monitoring of conveying pressure, material level, and flow, supports remote operation and maintenance, and reduces manual intervention.
