The purpose of iron separation.Its reaction is as follows：
2[Cu]+FeCl2(g)=Fe+2CuCl (g)
Product CuCl (1367 DEG C of boiling point) and unreacted FeCl after the completion of reaction2(boiling point is 1024 DEG C) is blended in
Is discharged using vavuum pump or carrier gas together.In discharge process, separated using the boiling point difference of the two, so as to by FeCl2
Decopper(ing) process is returned after processing.
Hot molten slag through supercooling, it is levigate after again with additive mixed-forming.The particle diameter of levigate slag and additive is smaller,
More can preferably it be reacted during subsequent calcination, the quality of obtained clinker is better.It is preferably real in the utility model
Apply in example, the particle diameter of levigate slag and additive≤0.074mm.
Levigate slag after additive mixed-forming with being used further to prepare clinker, in the utility model preferred embodiment
In, additive includes calcareous material, siliceous materials and aluminum material.The mass ratio of levigate slag and additive it is excessive or it is too small all
Have an impact to the quality of clinker, in the utility model preferred embodiment, the mass ratio of levigate slag and additive is
(6~9)：(91~96).
Shaping block can be preheated first before calcination, and it is more preferable that it calcines effect.In the utility model preferred embodiment
In, the temperature of preheating is 700 DEG C~800 DEG C.The temperature of calcining is too high or overlong time, wasted heat, and temperature is too low or the time
It is too short, the poor quality of obtained clinker.In the utility model preferred embodiment, calcining heat be 1300 DEG C~
1450 DEG C, calcination time is 30min~60min.
