The benefit of knowing your slope is so that you can create consistent, matched slope between your rollers, bases, and the unit in its entirety on your rotary kiln or dryer. Being aware of your slope can help ward off surprise issues such as unnecessary wear and poor thrust alignment.
Industrial Kiln & Dryer Group has created the Inclinometer to measure slope in both vertical and horizontal positions, offering exceptional accuracy with a resolution of .001 per foot slope.
