Typical Installation

The reason for this is three fold.  First, and foremost is HammerTek's patented vortice design, which enables material to change direction by deflection, as opposed to impact, as is the case with other elbows.  Second, all of HammerTek’s elbows are cast, meaning they are generally 3X thicker than standard long radius elbows.  Finally, HammerTek offers alloys ranging in hardness from 130 Brinell for SS, 555 for Hammerloy and 68 Rockwell for Tungsten Carbide coated elbows.

HammerTek has been solving degradation/ "streamer" problems for over 15 years.  It’s said that 70% of all streamers are caused by the elbows.  By implementing an industrial elbow that does not allow material to bounce off the walls, which causes heat and eventual streamers down stream, streamers can be reduced by 50-70%. 

The reason for our success with conveying elbows is HammerTek's patented vortice design.  This design enables material to change direction by deflection, as opposed to impact, as is the case with other conveying elbows.   HammerTek's conveying elbow actually "lifts" the material away from the outer wall, returning the product to laminar flow (not hitting the walls) within a distance equal to twice your conveying pipe diameter.  Compare 8" of "bouncing" to 6 - 8 feet for a standard long radius elle.

HammerTek eliminates the streamers by eliminating the main heat source (impact point) and the secondary heat source, the back of the conveying elbow as 80% of the pellets slide along the back wall of the long radius sweeps.  Feel your LRES and you will likely find them warm or hot.  Your product begins melting due to the heat and comes apart.  Generally you will see the interior tubing coated with plastic a few feet beyond the conveying elbow, as the air starts to cool the streamers they adhere to the tube.  We can eliminate this for you!

Customer Testimonial

John Brooks of Fletcher Limestone installed 16 HammerTek Wear Resistant Elbows to end premature elbow wear in his limestone dilute phase conveying systems in 2005. Today, nearly three years later all elbows continue to operate without one failure, which is unheard of with this product. John recently commented about his leeriness to spend so much money on these elbows upfront, but now sees the entire value. He summed it up by saying. "Those damn things are good!"
