Method for increasing mixing amount of mining and mineral separation waste stone chippings in cement
The invention discloses a method for increasing the mixing amount of mining and mineral separation waste stone chippings in cement. The method comprises the following steps: matching the following mining and mineral separation waste stone chippings (including sandstone, iron powder and raw material) with limestone in parts by weight: 81.1 parts of the limestone, 14.5 parts of sandstone, 4.3 parts of iron powder and 98 parts of raw material, wherein the mining and mineral separation waste stone chippings; the mining and mineral separation waste stone chippings and the limestone are mixed and stirred according to a proportion in a mining area by using a hooking machine or a loader, and then conveyed to a grinding machine to prepare cement. The method for increasing the mixing amount of the mining and mineral separation waste stone chippings in cement, disclosed by the invention, can be used for overcoming the defects of unstable cement quality, high cost, poor economic benefits and the like in the prior art so as to realize the advantages of stable cement quality, low cost and good economic benefits.
