ABSTRACT:
An arrangement is disclosed for supporting a rotary drum such as a rotary kiln resting upon a foundation. The support arrangement includes a weigh beam positioned in a horizontal plane and pivotally supported on the foundation. At least two carrying beams are poitioned in a generally horizontal plane adjacent said weigh beam and each of the carrying beams are pivotally mounted at one end thereof to the foundation and flexibly supported at another end thereof by the weigh beam. A roller for rotatably supporting the rotary drum is supported on the carrying beams by bearings. The support arrangement thereby effects a substantial mechanical equalization of the forces exerted on the roller during the rotation of the drum to warping and twisting of the drum.
