Spiral elevating conveyor handles hot catalyst
This company is providing an 18-in. spiral conveyor (photo) for the elevated transfer of various hot (~400°F) catalysts extrusions coming off a rotary calciner. The heat of the material causes severe maintenance problems when using a bucket elevator, resulting in unacceptable downtime. This Spiral Conveyor moves material vertically, solely through the action of twin external vibrators with no internal moving parts. It eliminates the heat-related maintenance problems of the bucket elevator with its many parts and also helps cool the material prior to the next process point. This machine is fabricated of 316 stainless-steel material-contact surface and includes a heat-resistant paint finish on external steel parts. — Vibra Screw, Inc., Totowa, N.J.
