Chain grate machine

Chain grate machine puts the balls that contains the iron on the grate plate in slowly feeding way, and uses the ring cooler waste heat and rotary kiln hot exhaust to dry, preheat, oxidize and consolidate the raw balls, then directly delivery the raw balls to the rotary kiln to roast, the roasting power on the chain grate machine will be collected by the ash hopper for reusing. The chain grate machine is a kind of equipment that operated in high temperature, and its main component adopts the heat-resisting alloy steel; Cooled measures are used on the segment of preheating roller, main transmission shaft and the supports of the Shovel stripper plate. Head unloading uses shovel mixture device and a set of the electric dust removal measures.
The chain grate machine greatly improves the heat efficiency by adopting the totally closed structure, and has the material layer height and thickness detection devices that uses for application and interlocking with the feeder, the quantitatively control can be carried out by adjusting the feeder speed . The machine is consisted of frame structure, shell parts, chain grate rotary part, thickness detection devices, drag feeder, transmission device, smoke room, deflecting preventing device etc ,the space between the grate plate and drag stripper plate can be controlled automatically, and reduce the wear down to its minimum
