Pneumatic conveying Palamatic Process bulk handling

Dense phase vacuum conveying with detached filter

A separating cyclone (offset filter) is coupled with a pneumatic conveying cyclone. The separating cyclone is fitted with a reintroduction nozzle for collecting aspirated fines continuously and for using them again in the process.

From a flow rate point of view, the introduction of a separating filter allows to eliminate filter cleaning cycles (10% of a cycle time on average).


Pneumatic conveying Palamatic Process bulk handling
Main functions :
1 - Cyclonic: air/product separation
2 - Storage: recapture of the material, preservation of expansion volume
3 - Finishes: separation and protection of the vacuum element
4 -  Reintroduction of the fines into the process or fines recovery in a dedicated hopper.

  • Fragile material
  • Fragile material

Equipment advantages

- No product loss: reintroduction of the powders into the process
- Implementation in harsh environments: loading of reactors in hazardous areas: protection of the filter against emanation of vapors, gas and dust area ATEX certification
- High rate process: optimisation of the cyclonic efficiency,  reduction of pressure losses, continuous unloading
- Difficult product conveying: protection of the filtering system, no clogging in the filter
