Guangxi Baise Chemical Mineral Powder Pneumatic Project

In the mineral powder processing sector, efficient and clean material handling is a critical factor for operational success. The Guangxi Baise Chemical Mineral Powder Pneumatic Project exemplifies how modern pneumatic conveying technology addresses core industry challenges. This article examines the project background, the client's operational difficulties, and the tailored solutions delivered.

Project Overview

A chemical enterprise based in Baise, Guangxi, specializing in mineral powder production, required a reliable material transportation system for their expanded production lines. The project involved moving various fine powders—including calcium carbonate, talc, and barite—from storage silos to processing units and packaging stations. The existing mechanical conveying methods had reached their performance limits, prompting the need for a more advanced solution.

Client Pain Points

Before the upgrade, the client faced several persistent issues:

• High dust emission: Open belt conveyors and bucket elevators generated substantial airborne dust, leading to material loss, equipment wear, and health hazards for workers.
• Frequent blockages: The fine, cohesive nature of mineral powders caused clogging in traditional conveying lines, resulting in unscheduled downtime and reduced productivity.
• Energy inefficiency: Mechanical systems consumed considerable power per ton of material moved, increasing overall operational costs.
• Limited automation: Manual intervention was required for routing changes and flow control, hindering scalability and real-time process monitoring.

Product Advantages & Solution

To overcome these challenges, a dense-phase pneumatic conveying system was designed and implemented. The solution brought measurable improvements across multiple dimensions:

• Sealed transport eliminates dust: The entire conveying pipeline is closed, preventing any powder leakage. Ambient dust levels dropped by over 90% compared to the previous setup.
• Reliable flow with anti-clogging design: Specialized air injection nozzles and optimized pipe bends ensure steady material movement, even for sticky or hygroscopic powders. Blockage frequency reduced by more than 80%.
• Reduced energy consumption: The dense-phase mode uses low air velocity and high solids-to-air ratio, cutting energy use per ton by up to 35% relative to dilute-phase alternatives.
• Full automation and remote control: A PLC-based control system manages start-up, shutdown, flow rate adjustment, and route switching. Operators can monitor and adjust parameters from a central control room, improving response time and reducing manpower.

The project has been operating steadily for over 18 months, with consistent throughput matching design capacity. Maintenance requirements have decreased significantly, and the client reports improved workplace safety and environmental compliance.
