Automatic Powder Weighing & Discharging Unit

The discharging system uses a series-tank design to feed powder continuously. A powder silo, a storage tank and an injection tank are connected in series for continuous pneumatic feeding

Balance pipes keep the pressure between the tanks in dynamic balance, and feeders deliver the powder, so the flow into the process does not stop. The system connects directly to the site's pipeline gas and is controlled by the on-site PLC

• Precision feeding: powder is metered with an accuracy of about ±1%
• Low energy consumption: the system runs on the site's pipeline gas through a direct connection, under on-site PLC control
• Stable operation: key wetted parts are made of wear-resistant ceramics
• Sealing: mechanical, oil or magnetic seals can be used
• High pressure: a maximum operating pressure of 4 MPa, for high-pressure process conditions
• Closed conveying: closed-loop conveying reduces dust emission

Powder feeding for a synthesis furnace

In service in a synthesis workshop. Technical data of this installation

• 
• The original feeding pipeline was kept unchanged. The continuous feeding system was added as a branch line, so the original feeding mode is not affected
  During maintenance of the continuous feeding system, the original pipeline can still feed the process, keeping the site in continuous operation

• 
• The revamped unit on site. On-site operating curves of synthesis-furnace temperature and pressure difference were compared, and reaction efficiency increased by 3%

• 
• After long-term service, inspection found no wear on the ceramic internals
