Hammertek SMART ELBOW® Deflection Elbows for Pneumatic Conveying Systems

Reduce wear in your pneumatic conveying lines with HammerTek® Corporation's SMART ELBOW® Deflection Elbow. The HammerTek Smart Elbow’s design uses a spherical chamber slightly beyond the 90° or 45° turn that creates a rotating ball of material suspended in the air that allows the chamber to capture a portion of the airflow traveling through the line and cause it to double back into the material stream, creating a deflection zone that eliminates elbow wear and product degradation. The deflection-action of the Smart Elbow can increase the lifespan of your pneumatic conveying system by several years. Contact one of our CMT process engineers for a quote or free consultation if you have questions regarding your pneumatic conveying line.

Features and Advantages

Reduction in Elbow Wear, Material Degradation, and Installation Space

Wear is one of the most common problems in pneumatic conveying systems. It is a problem that can cost tremendous amounts of resources in labor and replacement costs. Wear creates issues like elbow failure, formation of streamers, breakage, and dusting of fragile materials, and plugging and build-up. Our Process Engineers know that installing a HammerTek Smart Elbow instead of a conventional elbow can prevent many headaches and lead to a durable process system that ensures the quality of the end-product. The Smart Elbow design features a spherical chamber that protrudes partially beyond the desired 90° or 45° pathway, causing a ball of material suspended in air to rotate, gently deflecting
incoming material around the bend without impacting the elbow wall or generating heat. This simple, yet brilliant discovery was observed to cause material to rotate in the same direction as the airstream that powers it, which causes incoming material to be cushioned by the ball's rotation, and is gently deflected around the bend. The HammerTek Smart Elbow prevents impact with the elbow wall, essentially eliminating costly elbow wear, material degradation, melting and plugging. . The tight-radius Smart Elbow design requires roughly one-half to one-tenth the space needed to accommodate long-sweep elbows of equivalent diameter. This helps reduce space requirements in new installations and reclaim space in retrofit applications.

Minimal degradation aids dust control

The design of the Smart Elbow indirectly reduces dust by preserving product integrity and preventing material impact. Many plant managers have witnessed the benefits of the dust control that the Smart Elbow provides, noticing significantly less overall dust in their system. Smart Elbows provide better flow of material, resulting in less aeration and less dust as the product is conveyed out of the pneumatic line and into the next part of the process. This is a great advantage in applications with extremely dusty materials.

Reduction in Offload Times of Bulk Materials

Transfer times are an important measure of design efficiency in any dilute-phase pneumatic transport system, particularly when offloading bulk materials from trucks or railcars into storage silos. The Smart Elbow design decreases aeration and increases density, reducing the time a transport driver must wait for materials to settle as the silo fills up. Several Hammertek customers report improving their offloading times by up to 50% with the deflection elbow design vs. long-radius sweep elbows.

Improved Environmental and Safety Performance

The increase in durability and reduction of overall dust generated by the system has several environmental and safety performance factors. By significantly reducing the likelihood of an elbow wear-through, the risk of creating a polluting situation where bulk powder can escape from the system and increase employee exposure is minimalized. Generating less dust in the system through the implementation of the Smart Elbow also reduces the likelihood of dust collection filters clogging and causing a safety valve to release material into the atmosphere. Decreasing the load on filter media additionally minimizes the risk of a safety valve malfunction that could result in an over-pressurized dust collector being launched from its mounting.
