PLA pneumatic conveying solution for pellets
In the rapidly developing degradable plastics industry, PLA (polylactic acid) pellets are widely used due to their environmental properties, but during transportation, they often face issues such as material moisture absorption and caking, pipeline blockages, dust emissions, and excessive energy consumption. Traditional conveying methods struggle to balance efficiency and material quality, resulting in poor production continuity and persistently high maintenance costs. Head Powder focuses on industry realities, offering customized pneumatic conveying solutions to help enterprises overcome these conveying challenges.
Analysis of material properties
PLA particles are heat-sensitive, moisture-absorbing powdery and granular materials with a wide particle size distribution (usually 1-4mm). The particle surface is usually adhesive, making them highly prone to adhesion in humid environments. At the same time, PLA pellets have average flowability and are prone to bridging and delamination during long-distance or bent pipe conveying. These characteristics place high demands on the sealing of the conveying system, temperature and humidity control, and pipeline design.
Product Introduction: Head Powder PLA Particle Pneumatic Conveying System
With years of experience in powder and granular conveying, Head Powder has developed a sealed pneumatic conveying system specifically for PLA pellets. The system uses positive pressure dilute phase or dense phase conveying methods, combined with special treatment processes for pipeline inner walls, effectively reducing material adhesion; Equipped with a dehumidifying and drying module to control moisture at the source; The intelligent control unit can adjust conveying pressure and speed in real time to accommodate changes in particle sizes and batches. The complete equipment includes feeders, conveying pipelines, separators, dust removal devices, and electrical control systems, achieving fully automated conveying from feeding to the end of the process.
Product Advantages: Directly addressing pain points and providing reliable solutions
1. Relatively accurate temperature and humidity control to prevent caking: The system integrates heating and dehumidification components, allowing for fully adjustable environmental parameters throughout the delivery process, keeping PLA pellets dry and eliminating caking and blockage caused by moisture absorption at the source.
2. Low breakage rate design supports material quality: Uses low-speed feeders and optimized bend curvature to reduce material impact and friction, achieving particle integrity of over 98%, reducing dust generation and improving finished product yield.
3. Sealed circulation with no leakage, improving the working environment: Fully sealed pipeline connections, equipped with high-efficiency dust removal and recovery devices, achieving zero material leakage and low dust emissions, improving workshop cleanliness, and meeting environmental protection and safety production requirements.
4. Intelligent control and low-energy operation:P LC automatic control system dynamically adjusts fan frequency and air replenishment volume based on real-time conveying status, saving about 20%-30% energy compared to traditional methods; It also features fault self-diagnosis and remote monitoring functions, reducing inspection and maintenance frequency.
