Cement Kilns: Design features of rotary kilns

A significant step-change in hood design came with the Fuller grate cooler patent, which put heavy emphasis on the speed of cooling of the clinker and the aerodynamics of the secondary air. This led to the installation of deeper hoods, and the escalation of both hood depth and kiln diameter led to the abandonment of moveable hoods in the early 1960s.

Air bearing - Wikipedia

Air bearings (also known as aerostatic or aerodynamic bearings) are fluid bearings that use a thin film of pressurized gas to provide a low friction load-bearing interface between surfaces. The two surfaces do not touch, thus avoiding the traditional bearing-related problems of friction, wear, particulates, and lubricant handling, and offer
