A key feature of dense phase conveying is the exclusive air management system. By using a pressure control regulator, airflow control orifice and bypass valve, total airflow to the system and product-to-air ratio (the combination of air flow and conveying rate) are automatically controlled at the vessel.
When airflow and the product-to-air ratio are not accurately controlled, boosters or trace air lines are required. Not only are they expensive to purchase and install, but also add air to the system, increasing the energy requirements and line velocity. Our method saves money, allows easy access because all controls are located on the pot, and provides for an easier and more affordable installation.
Friction in a conveying line can only be overcome by pressure, not airflow. Airflow can increase or decrease friction, but pressure is the energy consumed to overcome the friction. The amount of pressure it takes to overcome friction is a function of product-to-air ratio, conveying line diameter, and conveying line length. Since line diameter and length are set, the only variable is product-to-air ratio. If the product-to-air ratio can be controlled, pressure can be controlled.
The key to unsurpassed system efficiency, reliability, flexibility, and overall performance is accurate control of airflow and product-to-air ratio at the vessel.
At Magnum Systems, we are confident of the superiority of our air management system that we include airflow meters on all of our Dense Phase systems. These tell you exactly how much valuable compressed air is being consumed.
