Embodiment 3
[0037] Industrialized CaO powder clinker homogeneous calcination method: using the industrialized powder clinker homogeneous calcination preparation equipment described in Example 2, comprising the following steps: grinding limestone into 70-100 mesh limestone powder, using a chain elevator to The limestone powder is transported to the suspension preheater 3 for suspension preheating, and then decomposed into CaO powder in the hollow suspension furnace 4 and the fifth-stage cyclone of the suspension preheater 3, and then calcined in the rotary kiln 7 The powder clinker is obtained, and finally the cooling speed is controlled by the grate cold dust collector 5, and the powder clinker is classified by dust removal to obtain powder clinker of different fineness. Among them, the temperature of the hollow suspension furnace 4 is controlled at 900°C, the temperature of the rotary kiln 7 is controlled at 1250°C, the fuel is coal gas, the grate cooling dust collector 5 is frequency-con...
