Method for preparing cement from manganese iron slag
The invention discloses a method for preparing cement from manganese iron slag, which comprises the following steps: (a) raw material crushing: crushing the raw materials mainly composed of limestone, manganese iron slag, shale, sandstone and iron ore to respectively obtain limestone particles, manganese iron slag particles, shale particles, sandstone particles and iron ore particles; (b) raw material prehomogenization: carrying out stratified piling on various particles obtained in the step (a); (c) green material preparation; (d) green material homogenization; (e) preheating and decomposition; (f) clinker firing; and (g) clinker milling: cooling the fired clinker, and milling the clinker to the required particle size, thereby completing the cement production. The method can improve the sinterability of the green material, improve the clinker quality, enhance the in-kiln decomposition rate, increase the operation rate of the rotary kiln, lower the clinker firing heat loss and cement comprehensive power consumption, enhance the cement yield and greatly lower the cement production cost.
