Case Study of Kaolin Dilute Phase Pneumatic Conveying Project for a Ceramic Enterprise in Qingyuan, Guangdong

Shandong Headpowder Engineering Co., Ltd. (brand abbreviation: headpowder) successfully delivered a customized dilute phase pneumatic conveying system for a leading ceramic manufacturer located in Qingyuan, Guangdong Province. This project specifically addresses the transport of kaolin, a critical raw material in ceramic production, with a focus on high efficiency, minimal degradation, and reliable operation. The system is designed to handle kaolin powder with a particle size distribution typical of ceramic-grade feed, ensuring consistent flow and low maintenance requirements. By implementing a dilute phase conveying approach, the client achieved significant reductions in energy consumption compared to traditional mechanical conveying methods, while also eliminating dust emission issues common in open handling processes.

The core challenge of this project was the cohesive and hygroscopic nature of kaolin, which often leads to bridging, clogging, and erratic flow in conventional conveying systems. headpowder's engineering team conducted a thorough analysis of the material properties, including bulk density, angle of repose, and moisture sensitivity, before designing a tailor-made dilute phase pneumatic conveying solution. The system utilizes a positive displacement blower as the air source, combined with a specially designed venturi feeder to introduce kaolin into the conveying line at a controlled rate. This configuration ensures that the powder remains suspended in the airstream without forming plugs, even over long distances exceeding 200 meters horizontally and with multiple vertical rises. The result is a stable, continuous material flow that meets the production demands of the ceramic plant, which processes over 50 tons of kaolin daily.

Key Features of the Kaolin Dilute Phase Conveying System

This dilute phase pneumatic conveying system is specifically engineered for ceramic raw material handling, with a particular focus on kaolin. Unlike dense phase systems that operate at high pressure with low air velocity, the dilute phase approach uses high air velocity (typically 20–30 m/s) to keep particles suspended in the pipeline. This method is ideal for fragile or abrasive materials like kaolin, because it minimizes particle degradation and equipment wear. The system includes acyclone separator and a bag filter for efficient air-material separation, ensuring that the conveyed kaolin is collected without contamination and that the exhaust air meets environmental standards. The conveying line is constructed from wear-resistant steel with a smooth interior surface to reduce friction and prevent material buildup. Additionally, the system incorporates automatic control valves and pressure sensors that allow the operator to adjust the conveying rate in real time, optimizing the balance between throughput and energy consumption.

For the ceramic industry, the ability to handle multiple raw materials—such as kaolin, feldspar, quartz, and clay—with a single conveying system is a major advantage. headpowder's dilute phase technology can be easily adapted to different particle sizes and moisture contents, making it a versatile solution for ceramic raw material conveying. In this specific case, the system was integrated with the client's existing storage silos, mixers, and ball mills, creating a seamless automated production line. The installation was completed within a two-week period, with minimal disruption to ongoing operations. Post-commissioning, the system demonstrated a conveying capacity of 8 tons per hour with a power consumption of only 0.5 kWh per ton, representing a 30% improvement over the client's previous mechanical conveyor setup. This energy efficiency directly translates into lower operational costs and a reduced carbon footprint for the ceramic enterprise.

Implementation Highlights and Technical Support

The project was executed under the close supervision of headpowder's senior project manager, Zhang Manager, who coordinated all phases from design to commissioning. The company's headquarters in Shandong, China, provided full engineering support, including 3D modeling of the pipeline layout, dynamic simulation of air flow, and stress analysis for the supporting structures. During the installation, headpowder's on-site team worked closely with the client's engineers to ensure that the system met all local safety regulations and operational standards. One of the critical design innovations was the incorporation of a rotary airlock valve with a specially coated rotor, which prevents kaolin from sticking and ensures a consistent seal. This component alone reduced maintenance intervals from monthly to bi-annual, greatly improving overall equipment effectiveness (OEE).

To guarantee long-term reliability, headpowder provided comprehensive training for the client's operational staff, covering topics such as start-up procedures, troubleshooting common flow issues, and routine maintenance of the blower and filter units. The company also offers a dedicated after-sales service hotline (contact person: Zhang Manager, WeChat: 15662777102) for any technical inquiries or emergency support. This level of commitment to customer service has made headpowder a trusted partner for ceramic enterprises across China and beyond. The Qingyuan project has since been featured as a reference case for other potential clients in the region, demonstrating the effectiveness of dilute phase conveying for challenging materials like kaolin.
