TORONTO (miningeekly.com) – The cast aluminium line of Smart Elbow deflection elbows from manufacturer HammerTek is now available in tube and pipe sizes from 3.8 cm up to 30.5 cm in diameter, helping to improve materials handling in dilute-phase and dense-phase pneumatic conveying systems applications.
The deflection elbows were said to eliminate problems associated with material impacting conventional elbows at high speed including abrasive wear, breakage of friable materials, plugging of heat-sensitive materials and generation of fines, plastic streamers, snake skins and angel hair.
The elbows feature a spherical chamber that protrudes partially beyond the desired 90 or 45 pathway, which caused a ball of material suspended in air to rotate, gently deflecting incoming product around the bend without generating heat or impacting on the elbow wall.
Other deflection elbows, offered in varying size ranges up to 45.7 cm, were available in cast iron, carbon steel, stainless steel and specialised alloys, which additionally prevented elbow wear when conveying sharp, hard or highly abrasive materials.
According to the Bethlehem, Pennsylvania-based manufacturer, conventional sweep elbows and ‘plugged tee’ elbows were typically replaced with deflection elbows to eliminate the cost of elbow replacements, ensure product quality, allow directional changes in restricted spaces and prevent unscheduled system shutdowns due to elbow maintenance or repair.
