Operating Details The Need For CEBMAG Backstops For some time, the trend in the cement and other pyro-processing industries has been toward larger and more efficient kilns. Since these kilns operate 24 hours per day, month after month, it has been important to conserve power and avoid down time as much as possible. The high degree of efficiency in the mechanical power transmission that has evolved also means that the kiln can roll back due to the large off-center mass of material in the kiln when power failure occurs or at any time the main drive is shut down. Uncontrolled rollback carries the...

Design Features and Size Selection Design Features A. The freewheeling clutch is contained in a completely dust and oil tight horizontally split housing, with provisions for supporting the freewheeling clutch, cam shaft, and secondary (worm) shaft. Liberal housing area is provided to insure adequate cooling of the lubricant. The freewheeling clutch elements are of the fully phased roller and cam type, consisting of cylindrical rollers contained in a precision machined cage, and actuated to engage all rollers simultaneously between the outer race and the inclined precision ground planes of the...
