In carbon black production enterprises, dust control and efficiency improvement in material delivery have always been a focal point of industry attention. Head Powder undertook the centralized negative pressure pneumatic conveying project for carbon black concentrated feeding in Jining, Shandong. Through systematic design, it achieved sealed and efficient delivery of carbon black powder, effectively improving the production environment and enhancing operational efficiency.

Case Summary

The project targets a large carbon black production enterprise, whose production process involves centralized feeding operations for multiple carbon black silos. The original process combined manual handling with mechanical lifting, which led to issues such as dust leakage, high labor intensity, and unstable feeding efficiency. Head Powder has customized a negative pressure pneumatic conveying system for them, enabling automated and sealed conveying of carbon black from the discharge point to each silo.

Customer pain points

During the preliminary research of the project, the prominent pain points faced by the client included:
1. Severe dust pollution: Carbon black particles are fine, and during manual feeding and transportation, large amounts of dust are generated, which not only affects the workshop environment but also poses health risks to operators.
2. Limited production efficiency: Traditional feeding methods rely on manual labor, resulting in small and slow feeding volumes per pass, making it difficult to meet the demands of continuous production line operation and prone to measurement deviations.
3. High maintenance costs: Mechanical lifting equipment has a high failure rate due to carbon black wear and dust clogging, and frequent shutdowns for maintenance disrupt overall production rhythm.
4. Insufficient space utilization: Existing equipment occupies a large amount of ground space, which is unfavorable for optimizing the factory layout.

Product advantages

To address these pain points, Head Powder's negative pressure pneumatic conveying solution has the following main features:
1. Fully sealed conveying: The system uses pipeline negative pressure suction, delivering carbon black directly from the source to the target silo under a fully sealed state, effectively preventing dust leakage and fundamentally improving the workshop environment.
2. Relatively accurate measurement and automatic control: Paired with weighing sensors and PLC control systems, feeding tasks can be automatically completed according to the set program. The feeding accuracy and consistency are significantly superior to manual operation, reducing human error.
3. Low energy consumption and reliable performance: The optimized aerodynamic design keeps system energy consumption at industry-appropriate levels. Key components use wear-resistant materials and are equipped with anti-clogging devices, effectively extending equipment lifespan and reducing maintenance frequency.
4. Flexible layout and expansion capability: Conveyor pipelines can be laid along the factory ceiling or walls without occupying ground aisles, and the system reserves expansion interfaces for future addition of silos or production line adjustments.
