Pneumatic conveying solution for resin particles

During the production and processing of resin pellets, many enterprises face issues such as low material conveying efficiency, severe dust pollution, high equipment maintenance costs, and insufficient automation. Traditional mechanical conveying methods easily cause pellet crushing, pipeline blockages, and are difficult to meet the demands of multi-variety, small-batch production. These pain points directly affect the stability of production lines and product quality, urgently requiring an efficient, clean, and flexible conveying solution.

Material Characteristic Analysis

Resin particles are usually cylindrical, spherical, or irregularly shaped, with particle sizes ranging from 1 to 10 mm, densities of about 0.9-1.5 g/cm³, good flowability, but prone to static electricity. Some resin particles are sensitive to temperature and must be avoided from adhesion or degradation caused by high temperatures. In addition, resin particles tend to generate fine dust during transportation, which places high demands on environmental protection and workshop cleanliness. Therefore, pneumatic conveying systems need to feature low flow rates, anti-static, good sealing, and relatively accurate temperature control.

Product Introduction

The pneumatic conveying system for resin particles provided by Head Powder is a customized solution specifically designed for the characteristics of resin particles. The system uses either positive or negative pressure pneumatic conveying principles, using airflow to transport resin particles from the storage silo to each usage point, operating in a fully enclosed manner. Core equipment includes rotary feeders, Roots blowers, cyclone separators, dust collectors, control valve groups, and PLC automation control systems. Based on customer site layout, capacity requirements, and material characteristics, we offer integrated system integration services ranging from single-point feeding, multi-point unloading to fully automated batching, weighing, and conveying.

Product advantages and solutions

To address customer pain points, the Head Powder Resin Particle Pneumatic Conveying System offers the following solutions:

• High efficiency and low loss: Uses low-speed airflow and special bend design to effectively reduce particle crushing rate, with conveying efficiency reaching over 95%.
• Clean and environmentally friendly: fully enclosed conveying, equipped with high-efficiency dust collectors, dust emission concentrations below industry standards, meeting environmental protection requirements.
• Intelligent control: PLC automatic control, supports remote monitoring and data collection, can integrate MES/ERP systems to achieve digital production management.
• Flexible customization: Adjust gas speed, material-air ratio, and pipe material for different resin types (such as PVC, PE, PP, PS, etc.) to suit various process scenarios.
• Low maintenance costs: Uses wear-resistant pipelines and easy-to-install seals, reducing downtime and maintenance time, and extending equipment lifespan.

Head Powder has been deeply involved in the pneumatic conveying field for many years, providing stable and reliable conveying systems for many resin manufacturers, continuously helping customers reduce costs and increase efficiency.
