Shandong Headpowder Engineering Co., Ltd. (referred to as Headpowder), headquartered in Shandong, China, has successfully delivered a comprehensive industrial salt conveying case for a major salt enterprise located in Hengyang, Hunan Province. This project represents a typical application of positive pressure pneumatic conveying technology in the salt material conveying engineering field, specifically designed for handling industrial salt particles with high efficiency, low degradation, and strict environmental compliance. The entire system was engineered to meet the customer's demanding throughput requirements while maintaining product integrity and minimizing operational costs. By leveraging decades of expertise in granular material handling, Headpowder provided a turnkey solution that integrates advanced pneumatic conveying principles with robust mechanical design. The project scope included system design, equipment manufacturing, on-site installation, and commissioning, all under the supervision of our experienced project manager, Mr. Zhang, who can be reached via WeChat at 15662777102 for any inquiries regarding similar industrial salt conveying projects.
The client, a well-established salt processing enterprise in Hengyang, needed to upgrade their existing material handling system for industrial salt particles. The original mechanical conveying method caused frequent equipment wear, salt particle breakage, and dust leakage, leading to product quality issues and environmental concerns. The primary requirements included a high-capacity conveying system capable of transferring 15 tons per hour of coarse industrial salt particles over a distance of 120 meters with an elevation change of 18 meters. The system had to maintain particle size distribution (P80 < 3 mm) with minimal fines generation, operate continuously under dusty conditions, and comply with local safety and emission standards. The positive pressure pneumatic conveying technology was chosen as the optimal solution due to its enclosed operation, gentle material handling, and flexibility in routing. Headpowder's engineering team conducted a thorough site survey and material characterization to design a customized salt material conveying engineering system that would address all these challenges effectively.
The core of this project is a dense-phase positive pressure pneumatic conveying system specifically tailored for industrial salt particles. Unlike dilute-phase systems that use high air velocities, dense-phase conveying operates at lower velocities (typically 3–8 m/s), which significantly reduces particle attrition and equipment erosion. Headpowder designed a system comprising a pressure vessel (blow tank), pipeline network, air supply unit, dust collector, and control system. The blow tank is equipped with a special fluidizing bottom to ensure uniform flow of salt particles into the conveying line. The pipeline is constructed from wear-resistant steel with internal bends to minimize pressure drop and particle impact. A rotary airlock feeder at the inlet ensures precise metering of material. The positive pressure generated by a screw compressor (0.6–0.8 MPa) propels the salt particles through the pipeline to the storage silo located 120 meters away. The entire process is fully automated, with PLC-based control system monitoring pressure, flow rate, and material level. This industrial salt conveying case demonstrates the capability of Headpowder's technology to handle hygroscopic and abrasive salt materials without clogging or degradation.
The major equipment supplied by Headpowder for this positive pressure pneumatic conveying project includes the following: (1) a 2.5 m³ pressure vessel with wear-resistant lining and fluidizing membrane, (2) a 110 kW screw compressor with aftercooler and moisture separator, (3) a 150 mm diameter conveying pipeline with 90-degree bends and diverters, (4) a pulse-jet dust collector with 99.9% filtration efficiency, (5) an automated control panel with touchscreen HMI and remote monitoring capability. All components were selected to withstand the corrosive nature of industrial salt. The blow tank is fitted with pressure relief valves and level sensors to ensure safe operation. The pipeline is supported by galvanized steel structures with expansion joints to accommodate thermal changes. The dust collector uses PTFE filter bags to prevent salt dust emissions. These components work together seamlessly to deliver reliable salt material conveying engineering performance. The system's design also incorporates easy access for maintenance and cleaning, which is critical for salt processing applications where residue buildup can cause contamination.
The project was executed by Headpowder's professional team in three phases. Phase one involved detailed engineering and 3D modeling of the conveying system, optimizing the layout to fit within the existing plant footprint. Phase two covered equipment fabrication and factory acceptance testing, where the system was tested with real industrial salt particles to verify performance. Phase three included on-site installation, wiring, and commissioning, completed within 6 weeks. The final system achieved a conveying capacity of 16.5 tons per hour, exceeding the customer's requirement by 10%. The particle breakage rate was measured at less than 2%, compared to over 8% in the previous mechanical system. Dust emissions were reduced to below 5 mg/m³, meeting strict environmental regulations. The customer reported significant savings in maintenance costs and improved product quality. This industrial salt conveying case has become a benchmark for other salt enterprises in the Hunan region.

Headpowder's approach to salt material conveying engineering offers several distinct advantages over traditional methods. First, the positive pressure pneumatic conveying system provides a completely enclosed material flow, eliminating dust pollution and product loss. This is especially important for industrial salt, which can be hygroscopic and prone to caking if exposed to moisture. Second, the dense-phase operation minimizes particle degradation, preserving the salt's physical properties and market value. Third, the flexible pipeline routing allows the system to navigate around existing equipment and structures, saving valuable floor space. Fourth, the automated control system enables precise material flow regulation and reduces labor requirements. Fifth, the system is designed for low energy consumption; the specific power consumption is only 0.8 kWh per ton of salt conveyed, which is 30% lower than conventional pneumatic systems. Finally, Headpowder offers comprehensive after-sales support, including spare parts, remote diagnostics, and periodic maintenance services. All these advantages make Headpowder the preferred partner for industrial salt conveying projects across China and beyond.
The Hengyang salt enterprise has expressed high satisfaction with the project outcome. In their official feedback, they noted that the system's reliability has exceeded expectations, with zero unplanned downtime during the first six months of operation. The plant manager specifically praised the ease of operation and the low noise level of the equipment. They also highlighted the responsive technical support from Headpowder's team, especially during the commissioning phase. This successful industrial salt conveying case has been featured in industry publications and has attracted interest from other salt producers in the region. Headpowder's reputation in the salt material conveying engineering sector continues to grow, with multiple similar projects now under negotiation. The company's commitment to innovation and quality is reflected in their continuous investment in research and development of pneumatic conveying technologies.
