An alumina company located in Xi'an, Shaanxi, needs to transport alumina powder from the raw material area to a distant processing workshop during its production process, with the transport distance exceeding several kilometers. Traditional mechanical conveying methods (such as belt conveyors and bucket lifters) suffer from high energy consumption, rapid equipment wear, and severe dust pollution, seriously affecting production efficiency and operating costs.

Customer pain points

• Low efficiency for long-distance conveying:Traditional mechanical conveying equipment has a high failure rate and lengthy maintenance downtime in long-distance scenarios, making it impossible to meet the demands of continuous production.
• Severe equipment wear:Alumina powder is highly hard and abrasive, causing wear and leakage in conventional pipelines and conveying components to occur in a short period and require frequent replacement.
• High energy consumption and environmental pressure:Mechanical conveying systems require large amounts of power to drive and have poor sealing that causes dust to leak out, wasting energy and increasing environmental management costs.

Product advantages and solutions

To address these pain points, Head Powder provided customized solutions for the projectLong-distance pneumatic conveying system for alumina。 This system uses sealed pipeline positive pressure conveying technology, combined with wear-resistant liner pipelines and a more accurate air flow control module, achieving the following breakthroughs:

• Ultra-long-distance stable conveying:The single-stage conveying distance can reach over 800 meters, and through intermediate relay stations, the transportation needs can be met for several kilometers, with no mechanical failure points throughout the process.
• Wear resistance and sealing:The inner wall of the pipeline uses high-chromium alloy linings or ceramic patches, increasing wear resistance by more than three times; The fully enclosed system eliminates dust leakage and meets environmental protection requirements.
• Intelligent energy-saving control:Automatically adjusts air source output based on material concentration and pipeline pressure, saving over 25% energy compared to traditional pneumatic conveying, while enabling unattended operation.

Project Outcomes

After the project was put into operation, alumina conveying efficiency increased by 40%, annual equipment maintenance costs decreased by 60%, effectively alleviating wear and dust issues during long-distance conveying, and becoming a benchmark case for pneumatic conveying in the alumina industry in Northwest China.
