Continuous grate track length compensator

摘要

An apparatus is provided for adjusting pallet wheel track length when the spacing between pallets changes due to temperature changes such as in the sintering of ore. The apparatus comprises pivotable arc segments which can be opened or closed to expand and contract the track length, a wedge-shaped casting positioned between said arc segments and slidable in and out at right angles to said track containing track to mate with said arc segments, drive means for moving said arc segments and wedge and a sensor means for detecting a change in pallet spacing and activating said drive means.
