Abstract

A grid cooler for cooling hot material such as cement clinker issuing from a rotating cement kiln including a generally horizontal movable cooling grid with stationary elements and horizontally and vertically movable elements, housing enclosing the grid with an inlet chamber extending over the kiln, sidewalls on the housing and vertically adjustable brackets on the sidewalls with cross shafts and vertical support pedestals on the cross shafts with the pedestal for the movable grid including an inclined cam arrangement, and a drive for the movable grid with pivotal support arms supporting the discharge end of the grid about an axis substantially coincident with the plane of the grid so that the angle of inclination of the grid may be adjusted by swinging the receiving end of the grid up and down and the grid pivoting about its discharge end.
