The fixed grate bed is used to receive the clinker dropped in the rotary kiln. The dropped clinker is radially scattered along the longitudinal center line of the fixed grate bed. The clinker layer is the thickest at the center line and gradually decreases. The thickness of the material layer decreases towards both sides, and the smaller the material layer thickness, the faster the cooling speed. Complete cooling of the material will affect subsequent production operations. Therefore, when ventilating the fixed grate bed, it is necessary to adjust the air volume of different sizes at different positions. Utility Model Content
