| titleOfInvention | A process technology for producing Portland cement clinker using high-silicon and low-calcium limestone |
| abstract | A process technology for producing Portland cement clinker by using high-silicon and low-calcium limestone, which comprises the following steps: taking low-grade limestone and high-grade limestone in proportion, mixing, crushing, and homogenizing, and then transporting them to a limestone batching warehouse of a raw material batching station ; The limestone, steel slag, raw ore iron powder, and aluminum ash in the raw meal batching station are proportioned to raw meal, and then weighed and batched by an electronic metering belt scale, and then dried and ground. The calcined raw meal enters the 5-stage preheater and decomposition furnace at the end of the kiln for dispersion, preheating, gas-solid separation and pre-decomposition, and then enters the rotary kiln for calcination for clinker calcination; the calcined clinker is cooled by the grate cooler. Transported into the clinker warehouse. The invention can widen the use range of raw limestone, reduce the investment and operation cost of mining projects, prolong the service life of limestone mines, improve the comprehensive utilization level of mine resources and promote the construction of green mines, and has good economic and social benefits. |
