HammerTek® manufacturers Smart Elbow® deflection elbows widely used in food manufacturing plants that pneumatically convey sugar, salt, nuts, seeds, spices, grains and other abrasives that cause elbow failure, incurring downtime and high replacement costs. The revolutionary design causes a ball of material suspended in air to rotate, gently deflecting material around the bend. Preventing impact with the elbow wall eliminates abrasive wear and prevents frictional heat responsible for melting, plugging, and build-up in conventional and plugged-tee elbows.
