This is the most commonly used method to transport materials. Dilute-phase conveying is the process of pushing or pulling air-suspended materials from one location to another by maintaining a sufficient airstream velocity. Dilute-phase conveying is essentially a continuous process, characterized by high velocity low pressure and low product to air ratio.
Dense-phase conveying relies on a pulse of air to force a slug of material from one location to another. Dense-phase system is essentially a batch process, characterized by low velocity, high pressure, and high product to air ratio. *** The choice between dilute and dense phase operation is typically dependent on the solids properties.***
Air-activated gravity conveying is a means of moving product along a conveyor on a cushion of air.
Today we boast a complete line of pneumatic conveying system solutions. We have experience in developing both negative and positive pressure systems from dilute to dense phase approaches for rail road car unloading, bulk bag unloading, bag dump stations and upstream process connection with destinations to silos, day bins, vacuum receiver or feeders.
