Abstract: Methodology for conveying hot Geldart group C materials. A slide plate for a slide of a conveyor for Geldart group C materials having a longitudinal axis, an up-facing surface for supporting the Geldart group C materials, a lower surface, a front-end surface and a rear-end surface may have a significantly reduced slope if the slide plate is made of a ceramic refractory such that the slide plate has a number of through holes configured to provide fluid communication between fluid inlets in the lower surface and fluid outlets in the up-facing surface.

Abstract: A grate bar (for forming a plank of a conveyor grate for transporting bulk material) includes at least an up-facing surface for supporting bulk material, a down-facing surface for supporting the grate bar on at least one grate bar rest, front end and rear-end sides, first and second profiled narrow sides. The first and second profiled narrow sides are complementary to one another and form a moving gap therebetween if and/or when the first profiled narrow side of the chosen grate bar is positioned adjacent to the second profiled narrow side of a neighboring grate bar (that is identical to the chosen grate bar at least with respect to the profile of the second profiled narrow side). The grate bar can be easily replaced if a front edge between the up-facing surface and the front-end side has a front edge curvature, a rear edge between the up-facing surface and the rear-end side has a rear edge curvature and the rear edge curvature is complementary to the front edge curvature.

Abstract: A clinker inlet distribution grate for feeding a conveyor grate with clinker, previously discharged from a kiln onto the clinker inlet distribution grate wherein the clinker inlet distribution grate comprises at least a chute with at least two grate elements being arranged one besides the other providing a chute enables to easily remove clinker agglomerations, so called snowmen if at least a first of said at least two grate elements is static and that at least a second of said at least two grate elements is movable orthogonally to the cross direction of the chute.

Abstract: A grate bar configured to include a reinforcement structure of sheet metal and structured to be manufacture at a reduced cost while exhibiting reduced wear and enhanced resistivity to hear and corrosives. A metal-ceramic compound grate (for example—an incinerator grate) utilizing such a grate bar. An incinerator and a cooling grate including such grate bar.

Abstract: A conveyor floor for conveying bulk material like cement clinker in a conveying direction from a bulk material inlet to a bulk material outlet, with longitudinal reciprocating planks which extend in parallel to the conveying direction and are arranged one besides of the other with moving gaps in between provides enhanced conveying at lower costs, if each plank has a mean coefficient of friction Cf for moving of the bulk material in the conveying direction relative to planks being significantly lower than the mean coefficient of friction Cb for moving of the bulk material against the conveying direction relative to the respective plank.

Abstract: A conveyor grate for the transport and cooling of bulk material, for example cement clinker, comprises a grate floor having multiple planks (12), adjacently situated transverse to the direction of transport on associated support structures and operationally moved longitudinally relative to one another individually or in groups, with moving gaps (14) designed as blow openings situated therebetween, and a method for operating such a conveyor grate. The mutually facing side edges or side edge regions of two adjacent planks (12) form two complementary, mutually engaging profiles between which the moving gap (14) is formed. In the method according to the invention, at least a quantity of the cooling air is blown through the moving gaps (14) which is sufficient to blow the moving gaps (14) completely open.
