Shandong Headpowder Engineering Co., Ltd. (referred to as headpowder) successfully delivered a customized cement hybrid pneumatic conveying system to a well-known building materials enterprise located in Shenzhen, Guangdong Province. This project focuses on the efficient and reliable transport of cement and other powder building materials using a combined positive and negative pressure hybrid conveying system. The client required a solution that could handle high volumes of cement powder while maintaining low energy consumption and minimal dust emission. headpowder's engineering team designed and installed a complete system that integrates both pressure and vacuum conveying technologies, ensuring seamless material flow from storage silos to multiple production points.
The core product deployed in this project is the cement hybrid pneumatic conveying system, which is specifically engineered for the building materials industry. This system utilizes a combination of positive pressure (blow tank) and negative pressure (vacuum) to transport cement powder over long distances and complex routing. The hybrid approach allows the system to handle varying material characteristics, such as fine cement particles that tend to fluidize and agglomerate. headpowder's design ensures that the cement is conveyed at optimal velocity, reducing pipe wear and preventing blockages. The system also incorporates advanced filtration and dust collection units, meeting stringent environmental standards. By using the hybrid conveying method, the client achieved a significant reduction in compressed air consumption compared to conventional pure pressure systems, leading to lower operational costs.
Building materials powder conveying is a critical process in the production of cement, mortar, and other construction products. headpowder's solution addresses the specific challenges of handling cement, fly ash, and other fine powders used in the industry. The system features a closed-loop design that prevents material loss and contamination. The conveying pipeline is equipped with wear-resistant bends and smooth inner surfaces to minimize friction and maintain consistent flow rates. In this Shenzhen project, the building materials powder conveying system was integrated with existing silo discharge equipment and a centralized control system, allowing operators to monitor and adjust parameters in real time. The reliability of the system has been proven over continuous 24/7 operation, with zero unplanned downtime reported during the first six months of commissioning.
The positive and negative pressure hybrid conveying system is the technological highlight of this project. Unlike traditional single-mode systems, the hybrid approach combines the advantages of both pressure and vacuum conveying. A positive pressure blow tank is used to push cement from the main storage silo to a intermediate buffer hopper, while a vacuum system pulls the material from the buffer hopper to multiple destination points. This configuration is particularly effective for plants with complex layouts or multiple discharge points. headpowder's engineering team customized the system's control logic to automatically switch between pressure and vacuum modes based on the material level and distance. The result is a highly flexible and energy-efficient conveying solution that can handle up to 50 tons per hour of cement powder. The client reported a 30% reduction in overall energy consumption compared to their previous pneumatic system.
The project was executed in three phases: site survey, system design, and installation & commissioning. headpowder's team conducted a thorough analysis of the client's existing infrastructure, including the layout of silos, production lines, and available compressed air supply. Based on the findings, the hybrid conveying system was designed with a compact footprint to fit within the limited space of the Shenzhen factory. During installation, headpowder provided on-site supervision and training for the client's maintenance staff. The system's automation features include remote monitoring via a PLC interface, enabling operators to detect potential issues before they affect production. Key benefits achieved include a 99.5% conveying efficiency, reduced dust emissions below 10 mg/m³, and a payback period of less than 18 months.

The cement hybrid pneumatic conveying system installed in Shenzhen features the following technical specifications: conveying capacity up to 60 t/h, conveying distance up to 300 meters, pipeline diameter of DN150, and working pressure range from -0.05 MPa to 0.6 MPa. The system utilizes a variable frequency drive (VFD) for the vacuum pump and a rotary valve feeder for precise material metering. The control system is based on Siemens PLC with an HMI touchscreen for easy operation. Performance data collected during the first three months of operation showed an average conveying speed of 12 m/s, a material-to-air ratio of 1:8, and a power consumption of 0.8 kWh per ton of cement conveyed. These figures demonstrate the system's high efficiency and low operating cost. headpowder also provided a comprehensive spare parts package and a two-year warranty, ensuring long-term reliability.
For building materials enterprises handling cement, the hybrid conveying system offers distinct advantages over conventional methods. First, it minimizes the risk of pipeline blockages because the vacuum section helps clear any residual material that might settle. Second, the combination of pressure and vacuum allows for longer conveying distances without requiring intermediate booster stations, saving both capital and space. Third, the system's ability to handle varying material densities makes it suitable for blending different powders or additives. In the Shenzhen project, the hybrid system was used to convey not only cement but also fly ash and slag powder, providing flexibility for the client's future product mix. This versatility is a key reason why headpowder's hybrid systems are increasingly adopted by leading building materials manufacturers across China.
