This article introduces a low-breakage pneumatic conveying project for resin pellets in Nagoya, Japan. The project was completed by Shandong Headpowder Engineering Co., Ltd., known as headpowder, a professional engineering company located in Shandong, China. Headpowder designed and supplied a complete conveying system to handle fragile resin pellets with minimal damage.

Resin pellets are widely used to make plastic films, injection-molded parts, packaging, and automotive components. During material handling, pellets can be broken by impacts and friction, leading to dust generation, quality defects, and production losses. Especially in a compact industrial plant in Nagoya, the conveying system must be gentle, reliable, and efficient. Therefore, low-breakage pneumatic conveying is an important technology.

In this Nagoya case, the main task was to transfer resin pellets from silos to several processing machines over a long distance. The pipeline included horizontal and vertical sections, so using ordinary dilute-phase conveying could easily damage the material. To solve this problem, headpowder adopted dense-phase pneumatic conveying technology. Dense-phase conveying uses high-pressure air and low velocity to move plugs of resin pellets through the pipeline. This method greatly reduces product breakage.

The engineered system consisted of a pressure vessel, rotary feeders, air control units, conveying pipes, and an automated PLC. The PLC monitored pressure, airflow, and material levels, adjusting the conveying cycle automatically. Pipelines were designed with large-radius bends and smooth inner surfaces to reduce friction, impact, and material buildup. These design details are critical for maintaining pellet quality.

Low-breakage performance was achieved through precise control. First, conveying velocity was kept below the critical point that causes pellet damage. Second, the ratio of pellets to air was optimized to form stable plugs and protect individual pellets. Third, pressure and pulse timing were controlled to create a smooth flow. Fourth, wear-resistant pipe materials reduced maintenance and prevented contamination. The final breakage rate was far below the customer's strict requirement.

This low-breakage pneumatic conveying case brought multiple benefits. The resin pellets maintained their original particle size, so final plastic products were consistent. The closed conveying system prevented dust leakage, improving workplace safety and reducing environmental pollution. Energy consumption was moderate, and maintenance was simple because the system had few moving parts. The compact layout also saved floor space in the busy Nagoya plant.

In addition, the system was designed for easy operation. The control interface displayed real-time data and alarms, allowing operators to adjust settings quickly. The equipment complied with local safety standards and required minimal supervision. This made the Nagoya project a practical and economical solution for the customer.

This East Asia pneumatic conveying project demonstrates the strong engineering capability of Shandong Headpowder Engineering Co., Ltd. The company delivered not only equipment, but also layout design, installation supervision, commissioning, and after-sales service. The project has become a reference case for low-breakage resin pellet handling. Similar solutions can be used by other manufacturers to reduce waste and improve production efficiency.
