Case Study of Positive Pressure Pneumatic Conveying Project for Talc Powder in a Papermaking Enterprise in Baoding, Hebei

This article presents a detailed case study of a positive pressure pneumatic conveying project for talcum powder implemented at a paper manufacturing enterprise in Baoding, Hebei Province. The project is a typical example of talcum powder conveying, positive pressure pneumatic conveying for powders, and papermaking filler conveying engineering. Shandong Headpowder Engineering Co., Ltd. (abbreviated as headpowder) served as the engineering contractor for this project, with its headquarters located in Shandong, China. The project contact person is Manager Zhang, available via WeChat: 15662777102.

Project Background and Customer Requirements

The customer, a large-scale paper mill in Baoding, Hebei, needed a reliable and efficient material handling system for talcum powder, which is used as a filler in the papermaking process. The existing mechanical conveying method caused frequent blockages, high dust emission, and significant material loss. The plant required a closed, dust-free, and automated solution to transport talcum powder from the storage silo to the paper machine headbox. After evaluating multiple suppliers, the customer selected headpowder based on its proven expertise in positive pressure pneumatic conveying for fine powders, especially in the paper industry. The key requirements included a conveying capacity of 5 tons per hour, a conveying distance of 80 meters, and a maximum vertical lift of 15 meters. The system also needed to minimize product degradation and maintain stable filler consistency.

System Design and Technical Solution

headpowder designed a complete positive pressure pneumatic conveying system specifically tailored for talcum powder. The system uses a rotary airlock valve as the feeding device, a Roots blower as the air source, and a series of conveying pipes with an optimized diameter to prevent blockage. The talcum powder, with a bulk density of 0.6–0.8 g/cm³ and a particle size of 200–800 mesh, tends to be cohesive and prone to bridging. To overcome these challenges, the headpowder engineering team incorporated a proprietary fluidization hopper at the feeding point, ensuring consistent material flow into the conveying line. The positive pressure system operates at a pressure of 0.2–0.4 MPa, providing stable material transportation without the risk of backflow. A dedicated control panel with PLC and HMI allows operators to adjust the conveying speed, monitor pressure, and set automatic cleaning cycles. The entire system is enclosed, effectively eliminating dust leakage and meeting the customer's environmental requirements.

Key Features of the Talcum Powder Conveying System

This talcum powder conveying case demonstrates several distinctive features of headpowder's positive pressure pneumatic conveying technology. First, the system achieves a high material-to-air ratio, reducing energy consumption while maintaining throughput. Second, the pipeline design includes smooth bends and wear-resistant materials to extend service life, especially important for abrasive talcum powder. Third, the system incorporates a dehumidification unit to prevent moisture absorption, which can cause clumping in the conveying line. The automatic control system also includes a fault detection function that alerts operators to any pressure drop or blockage. The entire system is designed for easy maintenance, with quick-release couplings and inspection ports. As a result, the Baoding paper mill experienced a 30% reduction in material waste and a 50% decrease in maintenance downtime compared to their previous mechanical conveying method.

Application in Papermaking Filler Conveying Engineering

In the papermaking industry, talcum powder is widely used as a filler to improve paper smoothness, brightness, and printability. The conveying of talcum powder from storage to the paper machine must be continuous and consistent to maintain the quality of the final product. headpowder's positive pressure pneumatic conveying system offers a clean and efficient solution for papermaking filler conveying engineering. The system can handle not only talcum powder but also other fillers such as calcium carbonate and kaolin clay. In this specific project, the filler conveying system is integrated with the existing paper machine dosing unit, allowing precise control of filler addition rates. The Baoding customer reported that the headpowder system reduced filler segregation and improved the uniformity of the paper sheet. The project also included a centralized dust collection system connected to the conveying line, ensuring that the workshop environment remains compliant with occupational health standards.

Project Implementation and Results

The implementation of the positive pressure pneumatic conveying project for talcum powder at the Baoding paper mill took approximately 8 weeks from design to commissioning. headpowder provided on-site supervision, training, and a comprehensive documentation package. The system passed all acceptance tests, including a 72-hour continuous operation trial without any failure. The customer noted that the system's noise level was below 75 dB, and the power consumption was 20% lower than the originally estimated value. The talcum powder conveying case has become a reference project for other paper mills in the Hebei region. Manager Zhang, the project contact from headpowder, stated that the company's extensive experience in positive pressure conveying for fine powders ensures reliable performance even under challenging conditions.
