High-silicon iron ore sintering pretreatment device based on centrifugal force principle

[0005] In order to overcome the problem that high-silicon and low-grade iron ore is extracted from iron ore, in order to prevent the problem that a large amount of fayalite will be produced under the high temperature conditions of the traditional reduction method, the prior art proposes a method to reduce high-silicon iron ore into white carbon Black device, when the existing device makes high-silicon iron ore into pellets to be sintered, a binder is added to the broken iron ore and internal blending coal and stirred to obtain a crushed material mixture, and the density of the iron ore is greater than that of the internal blending Coal density, resulting in higher iron ore content in the lower half of the crushed material mixture, that is, the low content of coal blending in the lower half of the mixture, which seriously affects the subsequent sintering step. In addition, the existing device mixes high-silicon iron ore and internal blending coal At this time, there will be voids in the pre-configured iron ore crushed mixture, which seriously affects the operation of the subsequent internal coal blending ratio. In addition, when the existing device mixes the internal coal blending into the vertical iron ore crushed mixture , there will be a shortcoming of the phenomenon that the internal blending coal gathers in the lower part of the iron ore scrap mixture, and the technical problem is: to provide a high-silicon iron ore sintering pretreatment device based on the principle of centrifugal force
