Abstract
A raw mixture for sintering, containing ore with a fines fraction, at least one addition, returned sintered material from a subsequent sintering process and optionally a binder produced by mixing followed by granulation. To achieve high throughput capacities while avoiding wear to installation parts and resultant operating failures, the returned sintered material is added after the ore has been mixed with the addition and with the optional binder.
Claims16
A process for producing a raw mixture for sintering, comprising mixing ore with a fines fraction, at least one addition, and returned sintered material from a subsequent sintering process and optionally with a binder, comprising mixing and granulation of the mixture, and adding the returned sintered material after the ore has been mixed with the addition and optionally with the optional binder.
An installation for producing a raw mixture for sintering, wherein the mixture comprises ore with a fines fraction, at least one addition, returned sintered material from a subsequent sintering process and optionally a binder, the installation comprising a mixer for mixing the ore, the addition and the binder which is optionally added, and downstream of the mixer along a path of the mixture in the installation a pelletizing device for the mixture, wherein the pelletizing device includes a granulating drum, and a delivery device operable to return sintered material to the mixture and the delivery device opens downstream from the mixer.
