Pneumatic Conveying Bends for
Recycling and Biomass

Variable Feed and Oversize

Recycling and biomass feeds can change in particle size, shape, moisture and bulk density from batch to batch. This variability can make a bend that behaves well during a test less reliable during plant operation. Include the expected range of material conditions, not only an average sample.

Blockage and Deposits

Fibrous particles, damp fines and oversize pieces may collect at restrictions or along a material pocket. Conveying pressure fluctuations, slowdowns and irregular feeding can make plugging more likely. A geometry should therefore be selected with an understanding of startup and clearing procedures.

Wear and Impact Resistance

Hard contaminants and abrasive particles can produce local wall loss, while larger pieces may create impact or shock loading. Candidate metal, hardfaced, basalt-lined or ceramic-lined constructions should be screened for both abrasion and impact resistance. A brittle lining is not automatically suitable simply because the feed is abrasive.

Cleaning and Maintenance Access

A predictable inspection or cleaning method is valuable where material properties are variable. Consider removable sections, support loads, available access, and the effect of replacing a heavy lined bend compared with a plain metal elbow.

Document the Operating Envelope

Provide material examples representing fine, coarse, damp and maximum-oversize conditions, plus throughput, air flow, operating pressure, bend location and known plugging events. Include maintenance records where available.

Request an Application Review

We can compare the proposed material and geometry choices against an existing pipe route and help define a practical replacement specification. Troubleshooting guide · Request quotation.
