Description
Pneumatic conveying - Dense phase pressure conveying - Pressure vessel - Suitable for abrasive or fragile bulk products MAXFLO®
Rate: 2 to 100 t/hr
Transfer of abrasive or fragile bulk solids
Dense phase pressure conveying is often used for abrasive or friable materials transfer. This equipment uses a slow and delicate transfer method for granules, powders and mixtures by using less compressed air and energy consumption.
High flow, low speed and long-distance Conveying
Palamatic Process offers dense phase conveying equipment, with the Inflatek® valve, to transfer material to the powder handling manufacturing line. This dense phase pressure conveyor system is suitable for abrasive and friable material transfer with a wide range of throughput rates and product temperatures.
Operating mode:
With dense phase pneumatic conveying, the valve cuts the product flow below the transfer tank. This tank, or transfer sluice, is fitted with a double case and a special output elbow that allows the slow movement of product through the piping or duct work.
This patented dense phase thrust (pneumatic) and sluice procedure optimizes the life of piping bends for up to two years against abrasion. This system also provides a guarantee of 1,000,000 operating valve cycles before general maintenance. Furthermore, the dispatching valve can be cooled by water circulation, which can be used for products with high temperatures in process.
• Product is inserted in the sluice
• The valve closes against the product flow
• Controlled air introduction
• The operation is repeated until the process is finished

DENSE PHASE CONVEYING SOLUTIONS
Dense phase - Full pipeline
- The difference in pressure is higher
- Material velocities are at their lowest
- Material fills the pipeline
Dense Phase - Slug Flow
- Dense phase dune flow
- The difference in pressure is medium-high
- Material velocities are low
- Material forms dunes while being conveyed
Dense Phase - Bed Flow
- The difference in pressure is medium
- Material velocities are medium to high
- The saltation velocity is achieved for some particles in the material which partially fluidises to convey above a bed of material moving slower
Lean Phase - Dilute Phase
- The difference in pressure is lower
- Material velocity is highest
- The saltation velocity for all the particles is achieved which causes the material as a whole to be conveyed within the gas stream
Equipment advantages
- Reduction in abrasion and material segregation
- Long distance conveying
- Gentle on friable materials
- Custom design to meet special requirements
- Available for any industrial process
