Project Title: PneumaticConveyingofUltrafineTCMPowderinRohtak,India. This article presents a comprehensive case study of a positive pressure pneumatic conveying system for ultrafine Traditional Chinese Medicine (TCM) powder in Rohtak, India. The project, originally titled "Indian Rohtak TCM Ultrafine Powder Pneumatic Conveying Project," was successfully engineered, manufactured, and delivered by Shandong Headpowder Engineering Co., Ltd. (headpowder), headquartered in Shandong, China. It serves as a notable example of pneumatic conveying in South Asia.

Keywords: pneumatic conveying case, South Asia pneumatic conveying, TCM ultrafine powder pneumatic conveying, positive pressure pneumatic conveying.

The client in Rohtak required a robust material handling solution for their traditional Chinese medicine production line. The ultrafine powder, with micron-level particle sizes, presents major difficulties for conventional mechanical conveyors, including material degradation, dust emission, cross-contamination, and pipe clogging. To overcome these issues, headpowder implemented a positive pressure dilute phase conveying system specifically tailored to pharmaceutical-grade TCM powder. The sealed system ensures safe, hygienic, and efficient material transfer.

System design: The equipment includes a feed hopper, rotary airlock valve, positive displacement blower, conveying pipeline, and a reverse jet bag filter. The powder enters the pipeline through the rotary valve and is conveyed by compressed air to the receiving silo. Positive pressure prevents external contamination and ensures complete discharge. Conveying velocity and air-to-material ratio were optimized to reduce particle attrition while maintaining the required throughput. Pipeline bends were minimized and internal surfaces polished to meet GMP standards and prevent powder build-up. Additionally, the system is equipped with a PLC controller and a touchscreen interface for easy operation and monitoring.

Key challenges and solutions: The ultrafine TCM powder is cohesive and hygroscopic. To avoid moisture absorption and caking, a dehumidified air supply and insulated piping were adopted. A pulse-jet filter cleaning system was integrated to enable continuous operation without blocking. The PLC-based control system monitors pressure and flow in real time. Safety features include overpressure relief valves, static grounding, and explosion-proof electrical components, which are essential for combustible organic dust.

Project implementation: Shandong Headpowder Engineering Co., Ltd. handled the complete project from design and manufacturing in Shandong, China, to export and commissioning in India. Local Indian contractors carried out installation under headpowder’s remote technical guidance. The system was commissioned on schedule and achieved stable operation, meeting the required conveying capacity. Performance tests showed consistent throughput and minimal material residue in the pipeline. Documentation and spare parts were provided to ensure smooth long-term maintenance.

Results and benefits: The positive pressure conveying system eliminated dust leakage, reduced labor, and improved production efficiency. The sealed line prevents product loss and cross-contamination, crucial for pharmaceutical applications. Energy consumption is lower than that of mechanical conveyors, providing long-term cost savings. The Rohtak client expressed high satisfaction with the reliability and professional service received from headpowder.
