MAC "Dilute Phase" Pressure Conveying
The approach of pressure conveying is typically used to convey from a single pick-up points to a single or multiple destination. The feeding of material into a pipeline typically requires a vented airlock feeder. The feed hopper can range from a bag dump station, bulk storage silo or bin, or any other bulk storage device.
These are considered low-pressure
conveying using a positive displacement pump to provide pressure up to 15 PSI. MAC offers complete blower packages from 5 to 500 HP
sized to meet the
desired convey rate.
The receivers can be either a cyclone or a combination filter/receiver that is sized and rated to meet the system demands with an appropriate discharge valve. MAC manufactures a complete series of collector, rotary feeders and cyclones that can be customized to meet your exact specifications.
Products commonly conveyed in dilute phase systems include flours, resins and compounds, specialty chemicals, ground feeds, granular and pelletized products. In many cases, the product needs to be evaluated based on process needs and possibly lab tested prior to final system selection to ensure the desired results can be achieved. Lab testing will also allow the product properties to be evaluated.
