Advantages of Dense Phase Conveying over Lean Phase Conveying
It’s been just over five years since Filquip supplied and commissioned a Stainless Steel 304 Air-Tec Systems 1500L 12TPA500 Dense Phase Conveyor for transporting Animal Feed Minerals, complete with a Dense Phase Diverter Valve and WAM Dust Collectors. During a recent site visit, we checked the Control Panel PLC to see how the system has performed over the past half-decade.
In five years, the unit has completed 44,630 cycles, moving approximately 1,150 kg per cycle. That’s an impressive 51.3 million kg of product conveyed—with only one inlet valve, one diverter valve seal, and two sets of dust collector filters replaced as part of routine maintenance.
When comparing lean phase and dense phase conveying, the higher upfront cost of a dense phase system often stands out. However, the long-term benefits such as minimal maintenance, reduced downtime, and lower energy costs per kg of product conveyed almost always deliver substantial savings over time. In terms of operational lifecycle cost, dense phase conveying consistently proves to be the smarter investment.
