This case study presents the successful implementation of a pneumatic conveying system designed for the transfer of lightweight powders in the Mishref area of Kuwait. The project, executed by Shandong Haide Powder Engineering Co., Ltd., focuses on the critical challenge of handling fine, low-density materials that are prone to dust dispersion and material loss. The system employs a vacuum-based negative pressure design to suppress dust flying, ensuring both operational safety and product integrity. The client required a reliable, automated solution to transport lightweight powders from storage to production lines without environmental contamination. Haide’s engineering team conducted a thorough site analysis and customized a closed-loop negative pressure conveying system that meets the specific needs of the Kuwaiti facility. The project highlights the expertise of Haide in delivering pneumatic conveying solutions for international clients, particularly in the Middle East region.
Pneumatic conveying is a widely adopted technology for moving bulk solids through pipelines using air or gas. In the Kuwait Mishref project, the material handled is a lightweight powder with extremely low bulk density, which presents unique feeding and conveying difficulties. Traditional mechanical conveyors often cause spillage, dust generation, and material degradation. Haide’s vacuum pneumatic conveying system operates under negative pressure, pulling the powder from a feed point into a sealed pipeline. The vacuum prevents any dust from escaping into the surrounding environment, effectively solving the anti-flying requirement. The system includes a vacuum receiver, a high-efficiency filter, a roots blower, and a PLC-based control panel. The conveying distance is approximately 50 meters with a vertical lift of 8 meters, achieving a capacity of 2 tons per hour. This case serves as a benchmark for similar lightweight powder applications in the chemical, food, and construction industries.
The vacuum anti-dust flying conveying system designed for the Kuwait Mishref project incorporates several advanced features. First, the negative pressure environment ensures that the lightweight powder remains contained within the pipeline, preventing any fugitive dust emissions. This is especially important for powders that are reactive or hazardous. Second, the system utilizes a specially designed rotary valve feeder that minimizes air leakage and maintains a stable vacuum. Third, the filter unit is equipped with pulse jet cleaning to handle high dust loads, ensuring continuous operation without clogging. The control system allows for remote monitoring and adjustable conveying speed, providing flexibility for varying production demands. The entire installation is compact and requires minimal floor space, making it suitable for retrofitting into existing facilities. Haide’s engineering team also provided on-site commissioning and training to the local operators, ensuring smooth integration into the client’s operations.

Manager Zhang is available to discuss project requirements and provide detailed proposals.
The vacuum conveying system installed in the Mishref facility operates with a negative pressure of up to 0.06 MPa. The conveying air velocity is carefully controlled between 12 and 18 m/s to avoid pipe erosion while maintaining particle suspension. The lightweight powder has a bulk density of 0.3 g/cm³ and a particle size distribution ranging from 10 to 150 microns. The system’s material-to-air ratio is optimized at 3:1 for efficient transport. The vacuum receiver is made of stainless steel 304 with a capacity of 200 liters, equipped with a level sensor to trigger the discharge valve. The filter cartridges are PTFE-coated for excellent release of sticky powders. The power consumption is approximately 18 kW, and the system operates at a noise level below 75 dB. These performance metrics demonstrate the system’s reliability and energy efficiency. The project was completed within the agreed timeline, and the client reported a significant reduction in material waste and dust emissions compared to their previous manual handling method.
