During the processing and transportation of PLA (polylactic acid) pellets, many companies face challenges such as material adhesion, pipeline blockages, degradation and deterioration, and dust pollution in the production environment. Traditional mechanical conveying methods easily cause particle breakage, while conventional pneumatic conveying systems lack targeted design, often resulting in low conveying efficiency and high energy consumption, and even frequent equipment shutdowns for cleaning, seriously affecting production continuity and product quality stability.

Material characteristics

PLA granules are heat-sensitive polymer materials with low melting points and glass transition temperatures, and are prone to adhesion or degradation due to frictional heating during transportation. At the same time, PLA pellets have significant surface static effects and strong hygroscopicity. If humidity control in the conveying environment is not properly controlled, particles can easily clump together, further increasing the risk of clogging. Additionally, the particle shape is irregular and the particle size distribution is wide, making it highly sensitive to wear and blockage in the pipeline.

Product Introduction

The PLA pneumatic conveying system launched by Head Powder is a sealed pneumatic conveying solution customized for the characteristics of PLA materials. The system uses positive or negative pressure dilute phase conveying methods, combined with dedicated feeders, wear-resistant elbows, filtration and separation devices, and intelligent control systems to achieve clean, efficient, and continuous delivery of PLA pellets from the storage silo to the terminal equipment. The main body of the equipment is made of stainless steel, with the inner wall polished to a mirror finish to reduce material residue; Key components feature anti-static and temperature control functions to prevent material performance degradation caused by local overheating or static accumulation.

Product advantages

To address customer pain points, the system offers the following comprehensive solutions:
1. Anti-clogging design: Equipped with an adaptive feed control valve and pulse backflow device, effectively preventing PLA particles from accumulating at corners and outlets, reducing downtime and cleaning frequency.
2. Temperature Control and Protection: Equipped with a temperature monitoring module in the pipeline, it automatically slows down or stops when the conveyed airflow or material temperature exceeds the threshold, avoiding the risk of thermal degradation.
3. Sealed and clean: Fully enclosed pipelines paired with high-efficiency dust collectors prevent dust leakage, meeting GMP and food-grade hygiene requirements.
4. Customized energy savings: Based on actual conveying distance, lifting height, and capacity requirements, it accurately matches fan power and pipe diameter, reducing energy consumption by more than 15% compared to traditional systems.
