Catastrophic failure of mud centrifuge

Description of Incident

While processing drilling fluids, a mud centrifuge (Fig. 1) experienced a catastrophic failure resulting in the ejection of the pillow block bearing assembly. The 65 lb. assembly travelled approximately 190 ft before striking the steps of a living quarter trailer (Fig. 2). The gearbox, back drive electric motor, coupler and associated components were also dislodged from the frame but remained within the confines of the centrifuge platform.
