An environmental protection company in Jingmen, Hubei, mainly engaged in municipal sludge disposal. Previously, after sludge dried, the products were transported manually and by vehicle, facing issues such as low efficiency, dust leakage, and high transportation costs. Enterprises urgently need an automated, sealed conveying system to enable continuous, dust-free transport of dried powder from the dryer discharge port to the storage warehouse or transfer vehicle.

Customer pain points

• Manual handling is labor-intensive, requiring six workers per shift, and the site has high dust concentrations, making occupational health risks prominent.
• Open transfer leads to powder dispersion, pollution of the surrounding environment, and frequent environmental complaints.
• Intermittent operations cannot keep pace with the continuous discharge rhythm of the dryer, requiring intermediate buffers, occupying space, and increasing equipment investment.
• Powder moisture content fluctuates greatly (about 15%~30%), conventional pneumatic conveying equipment is prone to pipe blockages, and maintenance frequency is high.

Solution

To address these pain points, Head Powder designed and delivered a complete pneumatic sludge drying powder pneumatic conveying system. Using positive pressure dense phase pneumatic conveying technology, combined with customized feeders and pipeline anti-blockage designs, powders within the fluctuating moisture content range are stably delivered to the target storage warehouse. The system operates in a fully enclosed manner, equipped with dust removal and filtration and intelligent control units, enabling unattended automatic conveying. After the project was put into operation, labor costs were reduced by 80%, on-site dust concentrations met national occupational health standards, and environmental complaints were fully eliminated.

Core system features

The system adopts a modular design and can be flexibly arranged according to site space; Conveying distance covers 50~200 meters, conveying capacity 0.5~10 tons/hour, suitable for various drying processes; The control logic has built-in pipe blockage prediction and automatic backblowing functions, ensuring continuous operation reliability above 99%.
