For a rotary kiln to perform at its best, the load must be evenly distributed along the supports. This is what we call axial balance. If the balance is off, the kiln pushes too much in one direction. This constant pressure overloads thrust rollers, bearings, tyres, and even the kiln shell and thrust device. Over time, the uneven forces cause excessive wear, overheating, cracks, and premature failure of these costly components.
