There are various means to ensure optimum performance of your powder transfer system.  Below are some of the simple, yet essential checks you can undertake:

1. It is important that the filter cleaning system used during powder transfer in operating efficiently. Filters are at the heart of any powder transfer system and should be checked and cleaned regularly.  Blocked filters can constrict the airflow and can significantly hamper throughput as a consequence.  Cartridge-type filters can be cleaned using a vacuum cleaner. Fabric-type filter bags can be washed.

2. Seals and gaskets must be in perfect condition and fitted properly to avoid air-leaks. Check seals and gaskets and remove any residual product that may cause air leaks. Similarly to above, any problems here can cause a significant drop in performance as the air flow suffers.

3. Air entrainment is vital to the correct operation of a lean-phase vacuum conveying powder transfer system.  It is important that adequate air-bleed systems are incorporated into and convey line and checked for correct operation allowing air to be introduced when needed. Hanningfield offers a range of air-entrainment devices to ensure peak performance is achieved.

4. Good ‘earthing’ of the system in essential to avoid static build up. Ensure all flexible hoses are embedded-wire type and correctly earthed at each end. Confirmation of a continuous ‘earth’ throughout the system should be checked periodically using a multi-meter.

5. Finally, all vacuum conveying powder transfer systems rely on a timed sequence of operations, such as convey duration, discharge durations and length of filter clean cycle etc. It is important that these settings are correct to provide optimum performance. Control sequences should be regularly checked.

If a system is not correctly maintained, performance levels can fall significantly. For process-specific recommendations and best-practice, please just ask a question to our team of experts by clicking here.
