Cement Kilns Design features of rotary kilns

Subsequently full-speed rotation of kilns in the range 0 5-1 5 rpm became standard and the gear meshed with a pinion running at 10-20 rpm The pinion shaft was driven by a gearbox Some kiln gearboxes derived their power from layshafts driven by a common electric motor or a steam engine but this was comparatively uncommon in Britain and most kilns had their own dedicated electric motor...
