This case study highlights a customized feed raw material mixed pneumatic conveying system successfully deployed for a major feed manufacturer based in Nanning, Guangxi. The client required a highly efficient, flexible, and contamination-free solution to handle multiple feed ingredients simultaneously, including corn, soybean meal, wheat bran, and various premixes. The system needed to support batch-wise batching with precise weighing, minimal material degradation, and low energy consumption. Shandong Headpowder Engineering Co., Ltd. (headpowder) was selected to design, manufacture, and commission the entire pneumatic conveying line, integrating both dilute-phase and dense-phase technologies to achieve optimal performance for diverse raw material characteristics.
The heart of this project is a full mixed pneumatic conveying system tailored for multi-ingredient feed batching. Unlike traditional mechanical conveyors (e.g., screw conveyors, bucket elevators), the pneumatic system uses pressurized air to transport materials through enclosed pipelines, offering superior hygiene, flexibility, and reduced maintenance. The system is specifically engineered for feed raw material mixed conveying, meaning it can handle multiple types of ingredients with varying particle sizes, moisture content, and bulk densities in a single integrated network. This enables the plant to achieve high-speed, accurate batching for up to 12 different feed formulations per day, significantly improving production efficiency.
One of the key challenges in feed manufacturing is the accurate and gentle handling of multiple ingredients. The multi-ingredient conveying system designed by headpowder employs a combination of rotary airlocks, pressure vessels, and diverter valves to sequentially or simultaneously transport different raw materials from storage silos to the main mixing tower. The system supports both positive pressure and vacuum conveying modes, ensuring that fragile materials like pellets or flakes remain intact. For the Nanning project, the client specifically required a multi-ingredient batching system that could handle up to 8 different feed ingredients per batch, with a total conveying capacity of 30 tons per hour. The system was equipped with real-time weighing sensors and PLC controls to maintain formula accuracy within ±0.1%.
The mixed pneumatic conveying system offers several advantages over conventional conveying methods. First, it eliminates cross-contamination between different ingredients because the pipelines are self-cleaning after each batch. Second, the enclosed system prevents dust emissions, improving workplace safety and compliance with environmental regulations. Third, the system requires less floor space and can be easily routed around existing equipment, making it ideal for retrofit projects. Additionally, the energy consumption is optimized through variable frequency drives (VFDs) on the blowers and precise air pressure control, reducing overall operating costs by up to 25% compared to older mechanical systems. The system's modular design allows for future expansion, enabling the client to add new ingredients or increase production capacity without major civil works.
The project in Nanning was executed in three phases: design, installation, and commissioning. During the design phase, headpowder's engineering team conducted a thorough analysis of the client's raw material properties, including particle size distribution, moisture content, and abrasiveness. Based on this data, they selected a hybrid conveying approach: dilute-phase for fine powders and dense-phase for granular materials. The system was installed over a period of 8 weeks, with minimal disruption to the existing production lines. After commissioning, the system achieved a conveying speed of 1.5 m/s for fine powders and 0.8 m/s for coarse grains, with a material-to-air ratio of 6:1. The client reported a 30% reduction in material breakage and a 20% increase in overall batching speed. The system also integrated seamlessly with the existing weighbridge and mixer control system, allowing for automated recipe management.
