Avoid Those Devilish 'Angel Hairs' | Plastics Technology

For more than 50 years, long-radius elbows have been used to change direction of flow in pneumatic conveying systems. The radius of these elbows is normally about 8 to 10 times the conveying pipe diameter. A 2-in. pipe system, for instance, would have a 16- to 20-in. radius bend, while a 4-in. system would have 32- to 40-in. radius bend.

Pneumatic Conveying Systems

Pneumatic conveying is the transport of bulk solids through a pipe by using the flow of air or other gas. Typical bulk materials pneumatically conveyed are powders, pellets, granules and irregularly shaped particles smaller than 20 mm [0.75 in].

Overcoming Long Conveying Distances

Vacuum conveying systems use air to pull resin materials through a pipe or tube. Pumps generate air flow to pick up and move resin through the piping of a conveying system. This air flow is typically defined in units of cubic feet per minute (cfm). Dividing this air flow by the cross-sectional area of the tube yields velocity in feet per minute ...

Material Conveying with Pneumatic and Vacuum Systems

Dense Phase Systems. The second category, high pressure systems, are known as dense phase systems. These systems utilize air pressure above 15 psig (up to 50 psig) in the pipe and use positive pressure to push materials through the conveying line at relatively low velocities (from 100 fpm to a maximum of 1000 fpm) much like extruding.

How to Maximize Your Conveying System Performance

The remedy is automatic purging, regulated by the conveying control and a valve at the material pickup point. At the appropriate point in a cycle, the valve closes to material and opens to outside air, conveying any material remaining in the line through to the designated receiver before the system begins to supply another destination.

Plastic material conveying systems

Pneumatic conveying uses compressed air to move very large volumes of materials through pipelines or hoses from one point to another. It is an extremely efficient way to cover distances from a few to hundreds of meters. While the definition of pneumatic conveying is simple enough, finding the optimal system for plastic (and properly sizing it) is a bit more complicated.

CONVEYING: Proceed With Caution

Speed kills" has been a popular road safety slogan for decades, but it's also appropriate for pneumatic resin conveying. As material moves faster, particles generate more heat, friction, and impact force, causing material degradation and contamination, pipe and elbow leaks, equipment and process failures, operational inefficiencies, added maintenance and …
