Vacuum Dense Phase Pneumatic Conveying

 

Vacuum dense phase conveying systems provide an efficient way to convey powders in a gentle manner where product degradation, heat retention, and/or segregation are process concerns.  Products are conveyed at lower velocities with lower air volumes and higher levels of vacuum. Some vacuum dense phase convey system characteristics/options are:

 

  • Special pick-up pan designed to prepare powder for conveying

  • Filter/receivers to separate air from product rated for high vacuum - many configurations

  • Discharge valve based on process requirements - butterfly valve, rotary airlock, slide gate

  • Vacuum pumps designed for high vacuum - access to top manufacturers

  • Batch or continuous process based on process requirements

  • Convey line air injectors to aid in conveying and to reduce chances of system plug

  • Slug product flow through convey line

Vacuum Semi-Dilute Phase Pneumatic Conveying

 

Vacuum semi-dilute phase conveying systems provide an efficient way to convey powders in a gentle manner where product degradation, continuous product flow, and/or segregation are process concerns.  While not operating in a true dense phase manner, these semi-dilute phase systems provide many of the benefits of dense phase systems while operating more efficiently by reducing air consumption, convey line sizes, and overall energy requirements.  Some vacuum semi-dilute phase convey system characteristics/options are:

 

  • Filter/receivers to separate air from product rated for high vacuum - many configurations

  • System air bleed valves modulated by unique control system to facilitate transfer at consistent levels of vacuum 

  • Discharge valve based on process requirements - butterfly valve, rotary airlock, slide gate

  • Vacuum pumps designed for high vacuum - access to top manufacturers

  • Batch or continuous process based on process requirements

  • Slug and moving dune product flow through convey line
