In a slaked lime powder processing and utilization project in Shaoguan, Guangdong, Head Powder designed and implemented a silo pump dense phase conveying system, which stably solved the problem of efficient slaked lime transport over long distances and under high head conditions. This system uses low-pressure, low-flow dense phase conveying methods, helping materials move smoothly within the pipeline, reducing pipeline wear and system energy consumption.

Customer pain points

Slaked lime (calcium hydroxide) powder has strong hygroscopic properties, is prone to caking, and has poor flowability. Traditional dilute phase or mechanical conveying methods often suffer from pipeline blockages, material caking, and severe equipment wear, leading to frequent shutdowns for cleaning, high maintenance costs, and inability to maintain production continuity. At the same time, dust leakage during transportation not only pollutes the environment but also causes material waste, affecting the normal operation of the overall process.

Solutions and product advantages

To address these pain points, Head Powder uses a silo pump dense phase conveying system. Through low-pressure, low-speed dense phase fluidization technology, slaked lime moves smoothly in clumps or plugs within the pipeline, effectively avoiding intense friction between the material and the pipe wall and reducing the risk of pipe blockage at the source. The system is equipped with a high-efficiency fluidization device and an automatic control unit, allowing real-time adjustment of conveying pressure and air volume according to material characteristics, ensuring a continuous and stable conveying process. The entire machine is designed with a sealed structure to prevent dust leakage, while integrating moisture-proof measures to prevent slaked lime from absorbing moisture and caking, supporting material quality. After the solution was put into operation, the customer's equipment failure rate dropped by over 70%, maintenance cycles were extended, and the goal of energy saving and efficiency improvement was achieved.
