Intelligent mixing device and mixing method thereof

Abstract

An intelligent mixing device includes a pellet raw material batching system (A), an intelligent mixing system (C) and a raw material conveying belt (B) installed between the batching system (A) and the intelligent mixing system (C). It is characterized in that: the intelligent mixing system (C) includes a mixing degree detection instrument (that is, a pellet raw material mixing degree detector) (C1), an intensive mixing control cabinet (C2) and an intensive mixing machine (C3), The mixing degree detector (C1) is set near the discharge port of the intensive mixer (3), the mixing degree detector (C1) is electrically connected to the strong mixing control cabinet (C2), and the strong mixing control cabinet (C2) is connected to the strong mixing control cabinet (C2). The mixer (C3) is electrically connected, and the strong mixing control cabinet (C2) is electrically connected to the batching system (A). The invention can detect the index of mixing degree in real time, and feed it back to the control system of the powerful mixer and the batching system to realize chain control, reduce the consumption of energy, equipment and bentonite, and reduce the production cost on the premise of ensuring the quality of green pellets.

Description

technical field [0001] The invention relates to a pellet production process in iron and steel smelting, in particular to an intelligent mixing device and a mixing method for pellet raw materials. Background technique [0002] In recent years, with the depletion of high-quality lump ore, fine ore and ultrafine fine ore have become the main raw materials for ironmaking. Due to the advantages of the pelletizing process in fine ore and ultrafine fine ore agglomeration, the pelletizing process has developed rapidly in recent years. development and maintained a good momentum of development. [0003] The mixing process is the core technical link of the pelletizing process and the core factor affecting the technical and economic indicators of the pelletizing process. The raw material of the pellets is mainly iron concentrate, which needs to be made into small balls of 8 mm to 16 mm before being roasted in the kiln. Since the concentrate powder itself has no cohesive force, it cann...

AI Technical Summary

Problems solved by technology

[0006] The amount of bentonite added is mainly determined by the quality of the green balls. The quality of the green balls is evaluated by the two indicators of drop strength and compressive strength. When the index is lower than the acceptance standard, it is unqualified green balls, but it is not necessary if the index is too much higher than the acceptance standard. Does not help production, but consumes more energy, equipment and bentonite, pure waste
