Since the start of the project, the engineering team has conducted a thorough site survey at the granary in Tianjin. The existing mechanical conveying system suffered from high maintenance costs and frequent blockages, especially when dealing with bulk wheat. Shandong Headpowder Engineering Co., Ltd. proposed a customized solution integrating wheat mixed conveying technology. This approach combines positive pressure and negative pressure in a single pipeline, allowing the system to handle both dense phase and dilute phase flows. The result is a highly efficient and gentle material transport process that preserves grain quality. The client, a major grain enterprise in Tianjin, required a system capable of moving 50 tons of bulk wheat per hour from the unloading pit to the storage silos, a distance of 120 meters with a vertical lift of 18 meters. The mixed pneumatic conveying engineering solution designed by headpowder met all these requirements while reducing energy consumption by 30% compared to the previous purely mechanical system.
The grain enterprise in Tianjin operates a large-scale storage and distribution center. Their existing conveying equipment was outdated and caused frequent downtime. The key challenge was to transport bulk wheat without damaging the kernels, as the wheat would later be used for milling and food processing. The client also needed a system that could handle the transfer of grain from multiple intake points to various silos, requiring a flexible routing capability. Shandong Headpowder Engineering Co., Ltd. was contacted after the client reviewed several case studies of mixed pneumatic conveying engineering projects. The headpowder team proposed a hybrid system that uses a rotary feeder for metering and a combination of a roots blower and a vacuum pump to create the necessary airflow. This design allows for the wheat mixed conveying mode to switch between high-speed dilute phase for long-distance horizontal transport and low-speed dense phase for vertical lifting, minimizing impact damage. The entire system was designed to be fully automated, with sensors monitoring pressure, temperature, and flow rate in real time. The project was completed within a tight schedule of three months, from design to commissioning.
The wheat mixed conveying system delivered for this project is a flagship product of headpowder. It employs a unique two-phase flow control algorithm that automatically adjusts the air-to-material ratio based on the physical properties of the bulk wheat. Unlike traditional pneumatic conveyors that use a single mode, the mixed conveying approach optimizes the transport process for each segment of the pipeline. For example, when the wheat enters the system from the hopper, it is initially conveyed in a dense phase to prevent segregation. As the material moves through the horizontal sections, the airflow is increased to maintain a steady velocity, preventing settling. At the vertical riser, the system switches to a higher air velocity to ensure the wheat kernels are lifted without slipping. This intelligent adaptability is what makes the wheat mixed conveying system ideal for grain transit and transfer. The system also includes a self-cleaning filter receiver that separates the wheat from the conveying air, ensuring that the grain is discharged cleanly and ready for storage. The entire process is enclosed, preventing dust emissions and protecting the working environment. The client reported that the new system reduced grain breakage by 45% and increased overall throughput by 20% compared to the previous setup.
Beyond the specific wheat application, Shandong Headpowder Engineering Co., Ltd. provides comprehensive solutions for grain transit and transfer across various types of bulk materials. The mixed pneumatic conveying engineering expertise allows the company to design systems that handle not only wheat but also corn, soybeans, rice, and other granular products. For the Tianjin project, the grain transit and transfer requirements were particularly demanding due to the need to move wheat from barges arriving at the port to the silos located 800 meters inland. Headpowder integrated a cascade of conveying stages: a marine unloading system using a suction nozzle, followed by a series of mixed pneumatic conveying lines that feed into a central distribution tower. The system was designed to handle peak loads of 80 tons per hour during ship unloading. The grain transit and transfer solution also included a bypass system that allowed the operator to divert wheat to different silos without stopping the main flow. This flexibility is critical for large grain enterprises that need to manage multiple varieties and grades of wheat. The entire system was built with stainless steel contact surfaces to meet food safety standards, and all components were designed for easy cleaning and maintenance. The client, a well-known grain enterprise in Tianjin, praised the robustness and reliability of the headpowder system, which has been operating continuously for over 18 months with zero unscheduled downtime.
The mixed pneumatic conveying engineering solution offered by headpowder stands out due to its advanced control system and energy-efficient design. For the Tianjin project, the engineering team used computational fluid dynamics (CFD) modeling to simulate the flow of bulk wheat through the pipeline network. This allowed them to optimize the pipe diameter, bend radius, and air velocity for each section, minimizing pressure drop and abrasion. The system uses a variable frequency drive (VFD) on the main blower, which adjusts the air supply based on real-time demand, saving up to 25% electricity compared to constant-speed systems. Another key feature is the use of a patented splitter valve that distributes the wheat mixed conveying stream to multiple destinations without causing material segregation. The control system is integrated with the client's existing SCADA, providing full visibility and remote operation. The headpowder team also provided extensive training for the client's operators, covering both normal operation and emergency procedures. The mixed pneumatic conveying engineering approach is particularly effective for materials that are fragile or have irregular shapes, as it allows gentle handling at low velocities when needed. In the case of bulk wheat, the system maintained a kernel damage rate of less than 0.5%, which is far below the industry standard of 2%. This performance has made the Tianjin project a benchmark case study for similar grain transit and transfer applications across China.
