Bulk Solids Conveying Fan

In the entire material handling system, the conveying fan is installed in the most demanding position to move bulk solid materials through a pneumatic pipeline. This unit is not only responsible for just moving air, also carries abrasive particles with air. Particles like cement powder, plastic pellets, mineral dust, chemical granules, and industrial fines hit the impeller with high velocity. This harsh environment quickly degrades a regular centrifugal fan, which is designed for clean air purposes. The pipeline plugs immediately when a fan stops in this pneumatic conveying system. To clear this blocked pipe will cost hours of production time.

Bulk Solids Conveying Fan designed to ensure facing this situation. For this unit, the most important is choosing an open-radial-blade or radial-tip impeller. Because closed geometry blades like backward-curved or forward-curved impellers accumulate material over time. But an open radial blade is designed as a flat and self-cleaning surface in front of the airflow. So, particles can discharge directly without accumulating and maintain the balance of the impeller. Impeller blade materials and thickness are determined based on the abrasive characteristics of the specific bulk solid being conveyed. These materials can be mildly abrasive plastic granules to highly abrasive mineral powders or cement. It is not a generic compromise design, it is engineered based on the specific demands of dilute-phase pneumatic conveying.

The Bulk Solids Conveying Fan provides 2000 to 12,000 m³/h airflows with 2260 to 7890 Pa static pressure. Which covers a dilute-phase conveying system for short to medium pipelines in chemical, plastics, mineral processing and industrial bulk handling facilities. This unit provides 75% maximum aerodynamic efficiency at the optimum working point. Overall, it can be a good choice for process engineers, plant managers and PC contractors designing bulk material handling systems for continuous operation, maintenance of balance and keeping the pipeline productive.
