News 2019 , daye peak cement company changed its thinking, actively explored and tested the use of new materials, summarized the research results in time, and successively declared 4 invention patents.
During the production of low-alkali cement, Daye Peak changed the traditional plan of using high-grade sandstone alone to replace part of sandstone and part of iron correction material with iron ore waste soil, which not only controlled the alkali content in the clinker, but also increased the content of Al2O3 in the clinker, ensuring the burnability and higher early strength of the clinker. Innovation has also been made in the raw material batching scheme, breaking the original high-grade and low-grade sandstones used together and changing them to separate batching of high-grade and low-grade sandstones respectively, thus avoiding the disadvantage of easy material segregation in the process of high-grade and low-grade sandstones used together. At the same time, the original four-component batching is changed to five-component batching, so that low-alkali clinker can be freely switched, which is convenient for production organization and production cost. On the basis of a series of innovative achievements, daye peak 2019 declared four invention patents, "a technology for producing clinker from gas sludge and dust collection in steel mills", "a method for treating sludge from machine-made sand mills", "an improvement in raw material batching method" and "a technology for producing low cement from iron ore mining waste soil", all of which have high practical value.
