Project Background
A large cement plant was experiencing serious wear in its pneumatic conveying pipeline for cement powder. The original carbon steel pipes required replacement every 3–4 months, resulting in frequent shutdowns and high maintenance costs. The customer was looking for a more durable solution to improve system reliability.
Customer Concerns
• Pipeline wears too fast
• Frequent shutdown for maintenance
• High labor replacement cost
• Risk of material contamination
• Need for longer service life
Solution
We recommend using high-alumina ceramic sleeves in high-wear straight pipes and elbows. The product features a 95% alumina ceramic inner lining, and the ceramic thickness is designed based on on-site working conditions.
