Embodiment Construction
[0040] A method for producing cement clinker with a dry precalcining kiln, the raw materials and the weight percentages of the raw materials are 1-60% of dicyandiamide waste residue, 20-85% of limestone, 5% of calcium carbide slag, and 8% of lime slag , waste silica 8-9%, iron powder 4% and electric furnace slag 4-5%;
[0041] A kind of method for producing cement clinker with dry method precalcining kiln is characterized in that: the method comprises the steps:
[0042] a. Limestone crushing and transportation: Limestone is fed into the single-rotor hammer crusher by the apron feeder through the unloading pit; the limestone mined in the mine has a particle size of ≤600mm, transported into the factory by car, and fed by the apron feeder through the unloading pit Single rotor hammer crusher. The crushed limestone is sent to the limestone homogenization storehouse through the belt conveyor. In order to homogenize and store the limestone, a long limestone pre-homogenization yard...
