Shandong Zibo Soda Ash Dense Phase Pneumatic Conveying Case

Case Overview

A leading soda ash producer based in Zibo, Shandong, faced persistent challenges in moving bulk material from storage to production lines. The existing dilute-phase pneumatic system caused high energy consumption, frequent pipe wear, and excessive dust emissions. After evaluating multiple solutions, the plant adopted a dense phase pneumatic conveying system designed by headpowder to achieve reliable, low-impact material transfer.

Customer Pain Points

The client's original system generated significant dust leakage during operation, leading to environmental compliance risks and increased cleaning costs. Abrasive soda ash particles accelerated pipe erosion, requiring quarterly replacements and unplanned downtime. High air-to-material ratios in dilute-phase conveying consumed excess compressed air, raising operational expenses. Additionally, the fragile soda ash crystals experienced breakage, reducing product quality and causing downstream handling issues.

headpowder Solution Advantages

headpowder's dense phase pneumatic conveying system addressed each pain point through tailored engineering. The design uses a high-pressure, low-velocity air stream to move soda ash in a plug-flow regime, drastically reducing particle impact against pipe walls. This lowers wear rates by more than 60% compared to traditional dilute-phase methods. The enclosed system prevents dust escape, meeting strict workplace air quality standards. A variable-frequency drive on the air compressor optimizes energy use, cutting overall power consumption by up to 35%. Furthermore, the gentle conveying action preserves crystal integrity, maintaining consistent particle size distribution and product value.

Field results from the Zibo installation demonstrated stable operation over 18 continuous months with zero unscheduled shutdowns related to conveying. The client reported a 40% reduction in maintenance costs and full compliance with local environmental regulations. headpowder provided complete system integration including pipeline layout, control software, and on-site commissioning support.
