Preliminary Engineering & Testing

engineering

A critical factor in system design is ensuring your material will pneumatically transfer reliably, efficiently, and at the rates and distances required. To help address these criteria, DDPS can provide preliminary engineering and testing at our Charlotte, NC facility where we utilize a QVF borosilicate glass Powder Pump and transparent transfer hoses to visually assess:

  • fill rates and cycle time setting
  • filter media performance
  • ease of material discharge
  • material flow characteristics

Projects

Bag Dump Station and Powder Pump with Loss-in-Weight Feeder

powder-handling-systems-img-2

For this project, a complete, integrated system was supplied that allowed powder to be charged into a bag dump station, pneumatically conveyed up to a charge hopper and then metered into the raw material stream via a loss-in-weight feeder. The project scope included:

  • pneumatic-assist bag handling unit
  • mezzanine structure for equipment installation and maintenance access

Pneumatic Conveying System
