EVA pneumatic conveying solution for pellets

In EVA pellet production, storage, and downstream applications, traditional conveying methods often face issues such as pellet damage, dust pollution, equipment blockages, and low efficiency. Customers needed a solution that could maintain particle integrity while enabling sealed, automated, and continuous conveying to reduce material loss, improve the working environment, and increase production cycles.

Material characteristics

EVA (ethylene-vinyl acetate copolymer) particles are characterized by their soft texture, high surface friction coefficient, easy static electricity generation, and sensitivity to temperature. The particles have average flowability, and if they are squeezed or sheared by external forces during transportation, they are prone to deformation, adhesion, or even clumping. Therefore, the material conveying system must operate at low speed, low crushing rate, and no temperature rise.

Product Introduction

The EVA pneumatic conveying system provided by Head Powder is a complete set of equipment specially designed for the properties of EVA materials. The system uses the principle of positive pressure dilute phase or dense phase conveying, using compressed air in a sealed pipeline to transport EVA particles from the source to the workstation. The complete unit includes core components such as feeders, conveying pipelines, cyclone separators, dust collectors, and automatic control systems. Customized designs can be made based on customer site layout, conveying distance, output requirements, and other parameters to achieve fully automated conveying from the storage silo to the processing equipment.

Product advantages

To address customer pain points, Head Powder focuses on optimizing the following aspects in system design:
- Low crushing and conveying: Uses a specially structured feeder and low-speed fluidization technology to effectively prevent pellet impact and compression during feeding and conveying, maintaining the original state of the pellets.
- Fully sealed with no leakage: System pipelines and interfaces are equipped with sealing components, paired with high-efficiency dust collectors to achieve no dust overflow and support workshop cleanliness.
- Anti-static and temperature control: The inner walls of pipes are treated for anti-static electricity and use air cooling measures to prevent material adhesion caused by frictional heat.
- Intelligent control adjustment: The programmable logic controller (PLC) automatically monitors conveying pressure, material flow, and gas-solid ratio, adjusting feeding speed in real time to help maintain stable conveying while reducing energy consumption.

Head Powder provides comprehensive services from solution evaluation, equipment selection to installation and commissioning, helping the EVA particle pneumatic conveying system operate continuously and helping customers improve production efficiency and product quality.
