Abstract
A mechanism for the cooling of bulk materials such as hot cement clinker emerging from a calcining furnace with a materials transfer device for receiving hot discharge from a furnace into the cooling mechanism with the cooling mechanism having a first cooling section with an immobile stepped grate inclined relative to the horizontal whereby material passes from a receiving end to a discharge end, also having a second cooling section positioned so that the material to be cooled is discharged from the first cooling section onto a receiving end of the second cooling section which includes a sliding grate, and a third cooling section having an immobile inclined stepped grate positioned to receive material from the discharge end of the second cooling section and passing the material over the third cooling section to a discharge end.
