Abstract: A grate bar for mounting in arrays of adjacent grate bars in a pallet car of a sintering or pelletizing machine includes an elongate crossbeam extending in a longitudinal direction of a horizontal plane, with a middle section between two opposite end sections. The crossbeam has a generally rectangular cross-section with an upper surface for receiving bulk material thereon, an opposite lower surface, and peripheral surfaces for facing adjacent grate bars. The crossbeam has two legs to vertically secure the grate bar to the pallet car. The end sections of the crossbeam include first interlocking components shaped and arranged such that they cooperate with first interlocking components of grate bars of a neighbouring row of grate bars; thereby limiting relative translations of two neighbouring grate bars in at least a vertical and a horizontal orientation. The first interlocking components have a triangular cross-section in a horizontal plane.

Abstract: A method for fitting or retrofitting a sinter cooler, which sinter cooler has a cooler grate chain with an endless chain of cooler cars, the method including, installing a lamella grate for holding sinter material and allowing air flow through the grate so that a support structure is connected to the cooler car and a plurality of lamellae are supported by and individually movable with respect to the support structure, and are disposed to allow air flow between neighbouring lamellae, where the support structure has at least one support element disposed underneath the plurality of lamellae to support the plurality of lamellae, and at least one downholder that is adapted to limit an upward motion of at least one lamella installed such that at least a portion of the downholder is disposed above the at least one lamella.

Abstract: The invention relates to a method for fitting or retrofitting a sinter cooler (1), which sinter cooler (1) comprises a cooler grate chain with an endless chain of cooler cars (2). In order to provide means for increasing the effectiveness of the sinter cooler, the invention provides that the method for fitting comprises, for at least one cooler car (2), installing a lamella grate (10) for holding sinter material and allowing air flow through the grate so that a support structure (13) is connected to the cooler car (2) and a plurality of lamellae (12) are supported by and individually movable with respect to the support structure (13), and are disposed to allow air flow between neighbouring lamellae (12).

Abstract: An induration machine includes a travelling grate for transporting bulk material along a transport direction from a heating zone for heating and/or drying the material to a cooling zone for cooling the material by cooling gas. The machine includes a hood disposed over the travelling grate having a first hood section in the heating zone and a second hood section in the cooling zone; and two recuperation ducts for guiding used cooling gas from the second hood section to the first hood section. The recuperation ducts are disposed on opposite sides of the hood, are laterally offset with respect to the hood, and are connected to the second hood section by a V-shaped gas collector duct. Each recuperation duct is connected to the first hood section by at least one gas supply duct and has at least one dust purge opening disposed in the lowermost part of the recuperation duct for purging dust from the recuperation duct.

Abstract: A device for measuring the temperature in a rotary kiln through which solid material passes being heated to elevated temperatures. The device features a drive as well as an elongated hollow body with means to fix a thermocouple, whereby the drive and the elongated hollow body are mounted such that they rotate jointly with the rotary kiln. The drive can move the elongated hollow body together with thermocouple through an opening in and out of the rotary kiln interior for measuring the temperature inside the rotary kiln during operation.

Abstract: A side wall of a pallet car for a travelling grate machine including an upright portion, a wing portion and a lower connection flange, where the wing portion has an upper surface acting as an extension of a loading surface of the pallet car, the upper surface of the wing portion being arranged at an angle with respect to the horizontal.

Abstract: This invention relates to a machine for the thermal treatment of bulk material, in particular a sintering or pelletizing machine, comprising a travelling grate (4) with a plurality of pallet cars (3), that are conveyed through at least one treatment station for effecting the thermal treatment of the bulk material, and a sealing structure sealing the pallet cars (3) against the machine, wherein the sealing structure comprises a spring-loaded sealing strip (15) contacting a planar sealing surface (16, 20). It is provided that the sealing strip (15) is held by a leaf-spring element (13) biasing the sealing strip (15) against the sealing surface (16, 20).

Abstract: A device for changing a pallet car in a plant for the treatment of bulk materials where pallet cars that are continuously conveyed using a lifting wheel and a lowering wheel on an outer rail and an inner rail in an endless chain includes, in regions of a bottom and top strand of the lifting wheel, first and second outer curve links of the outer rail that are openable such that the pallet car is removable from the chain and another pallet car is insertable into the chain. A removal switch is disposed in the region of the bottom strand of the lifting wheel, via which the pallet car is movable out from the chain, and a supply switch is disposed in the region of the top strand of the lifting wheel, via which the pallet car is insertable into the chain.

Abstract: A grate carriage for receiving bulk material includes a plurality of grate bars arranged, parallel to each other from a first side to a second side of the grate carriage. The grate bars are movably held in lateral receptacles of the grate carriage and a gap is provided between each adjacent pair of the grate bars. A force application device is arranged on each of the first and second sides of the grate carriage and configured to elastically press the grate bars against each other.
