CEMENT CLINKER PREPARED BY MICROWAVE ON LARGE SCALE AND PREPARATION METHOD THEREOF

The present invention relates to the technical field of production of cement clinker by microwave sintering, in particular to cement clinker prepared by microwave on a large scale and a preparation method thereof. The preparation method includes the following steps of: taking CaCO3 powder and SiO2 powder as raw materials for preparation, adding a sintering aid for mixing uniformly to obtain mixed powder, pre-pressing the mixed powder into a rough body, and performing microwave sintering on the rough body at 1000-1500℃ to obtain cement clinker. The present invention provides a method for large-scale preparation of cement clinker by microwave, which effectively reduces the synthesis cost of mineral materials for traditional cement clinker, and improves the synthesis efficiency. In addition, the sintering method is short in time, high in yield, good in repeatability, and low in the cost of scale preparation, which is particularly suitable for industrialization and scale production needs.
