Chemco – Deflection Elbows for Abrasives

Chemco Sysems is employing deflection elbows in its silo feed lines that convey powdered activated carbon, pebble and hydrated lime, sodium carbonate, fly ash, potassium permanganate and other bulk chemicals used for air and water treatment at municipal, industrial, mining, food processing, and pulp and paper facilities.

“All the materials our clients work with are abrasive and, over time, any type of elbow will degrade if it isn’t specifically designed to handle them. For us, the two options are the HammerTek deflection elbow or our own wear-back elbow.” says Marcus Bollman, project engineer.

Chemco’s own elbow is a standard rolled 90-degree pipe with rolled steel welded to the back. The HammerTek design has a bulb-like protrusion where a loose ball of material rotates in the same direction as the airstream that powers it, deflecting material around the bend without impacting or wearing the elbow wall, preventing blow-outs. Material comprising the ball gradually self-renews as it continuously filters out of the chamber as new material enters.

"Long-term wear resistance is critical, because once the elbows are installed, they can be difficult to access...plus the downtime and the cost of a new elbow add up.” Bollman continued.
