Inter-Source: Conveyors: Pneumatic


Moving chips is typically handled pneumatically or mechanically.

Pneumatic conveyors employ air to move material. Either positive pressure (blowing) or vacuum (sucking) can be used. Often the pressure created by the wringer can be used to power the conveyor. Pneumatic conveyors are typically installed overhead.

This list includes some of the pneumatic conveyors Inter-Source has engineered for clients:

6. Rotary Airlock

Rotary airlock mechanically introduces high volumes of dry chips into a pressurized pneumatic conveying system for transport over distances of a couple hundred feet to over 1,000 feet.

Chips can be discharged into silos, hoppers, bunkers, rail cars, or van-type trailers.

7. Cast Elbow Segments

In high volume and / or abrasive chip applications, the portions of cast elbow segments that receive the most wear have additional thickness, ensuring long life. A dime appears in both photos to show the width variation.

The elbow’s cast construction allows for heat treating, in addition to the extra material protecting the area of high wear.

The single 15 degree cast segment also provides for assembly of any elbow size, up to 90 degrees. Wear is inevitable even with these superior elbows, but the segmentation allows for portion replacement, not the entire elbow as fabricated elbows require.

8. Blowers

Blowers pneumatically transport dry chips for distances beyond what wringer forces can propel them, and / or following magnetic separation. There are three general types of blowers: scroll, pressure and turbine. The type utilized depends upon the volume of chips to be moved and the distance. Dry chips may be moved significant distances with this technology.
