Low-energy-consumption cement clinker taking tungsten tailings as raw material and preparation method of low-energy-consumption cement clinker
The invention discloses a low-energy-consumption cement clinker taking tungsten tailings as a raw material, which comprises the following raw materials in parts by weight: 3-24 parts of tungsten tailings, 70-85 parts of limestone, 5-18 parts of siliceous material and 0-5 parts of ferrous material, and the tungsten tailings contain 3-35% of mineral fluorite. The cement clinker disclosed by the invention can directly consume a large amount of tungsten tailings, and the sintering of the cement clinker is mineralized by utilizing elements such as fluorite in the tungsten tailings, so that the sintering temperature in a kiln is reduced, and the coal consumption is greatly reduced while the clinker quality is ensured.
本发明公开了一种以钨尾矿为原料的低能耗水泥熟料，包括以下重量份数的原料：钨尾矿3‑24份、石灰石70‑85份、硅质材料5‑18份、铁质材料0‑5份，其中钨尾矿中含有3‑35％的矿物萤石。本发明的水泥熟料可以直接大量消耗钨尾矿，利用钨尾矿中的萤石等元素矿化水泥熟料的烧成，降低窑内烧结温度，保证熟料品质的同时大幅降低煤炭消耗。
