Abstract
The present invention relates to a method of using electrolytic manganese slag to produce cement, which uses limestone, electrolytic manganese slag, iron power, fluorite and anthracite coal. The raw materials are mixed to be ground, warehoused and homogenized, the raw materials are transported to double stirrers to be watered and stirred, and the raw materials become balls by a balling dish and are calcined into cement clinker by a kiln. The electrolytic manganese slag can replace clay and can produce cement in a 42.5 grade and a 32.5 grade. The strength or the stability of cement produced by clay is the same as that of cement produced by electrolytic manganese slag. Because of the application of electrolytic manganese slag, pollution is reduced, and new resources are found for cement production. The electrolytic manganese slag is suitable for producing cement.
Description
Technical field:
The present invention relates to produce cement particularly a kind of cement that utilizes electrolytic manganese residues to produce with the manganese slag.
Background technology:
Present electrolytic manganese residues is used for a kind of acid industrial pollution waste residue with manganese, and a large amount of dischargings causes the permanent pollution in arable land and brings serious water pollution to rivers, does not up to the present also utilize electrolytic manganese residues to produce the method for cement.
Summary of the invention:
The object of the present invention is to provide a kind of cement that utilizes electrolytic manganese residues to produce, the application of electrolytic manganese residues can not only replace clay, and can reduce the pollution of electrolytic manganese residues to environment, reaches protection soil, the purpose that turns waste into wealth.
Formation of the present invention: it is made up of following components in weight percentage: Wingdale 63～63.5%, electrolytic manganese residues 19～19.5%, iron powder 1.5～2%, fluorite 1.3～1.8%, hard coal 13.2～13.7%.
Above-mentioned raw materials is mixed the back grinding, and the warehouse-in homogenizing is transported to biaxial rneader, adds water and stirs, and to the pan-pelletizer balling-up, kiln is sintered into cement clinker.
Carry out grinding after will above-mentioned raw materials mixing, fineness control 0.08mm tails over 10% ± 1, enter the pre-homogenizing of silos after, be transported to biaxial rneader by the bottom of the reservior and add water in advance, amount of water is 11% ± 1, and wet feed stirs the back to the pan-pelletizer balling-up, the balling-up particle diameter should be controlled at 8～12mm, ball is transported to kiln by belt and carries out high-temperature calcination, and firing temperature should be controlled at 1300 ℃ ± 50 ℃, clinker strength 3 days, anti-folding 5.8mPa, resistance to compression 31.5mPa, 28 days anti-folding 8.4mPa, resistance to compression 54.9mPa.
There is technology relatively with sight, electrolytic manganese residues of the present invention is a kind of industrial residue, repeatedly study and test through us, obtained the experience of more electrolytic manganese residues, particularly how in cement, to replace clay with electrolytic manganese residues, can produce high-quality, the existing new breakthrough of cement of high index, in manufacture of cement, electrolytic manganese residues is configured in the raw material according to a certain percentage, in the time of feasible in front, electrolytic manganese contains more vitriol, and a good conditions is created in calcining to kiln.
Advantage: 1, electrolytic manganese residues is when producing electrolytic manganese, and starting material are through grinding, and fineness is thinner; 2, its Chemical Composition, aluminium sesquioxide (AI
2O
3), ferric oxide (Fe
2O
3) and clay approaching, can satisfy the needs that form cement minerals; 3, thin because of the electrolytic manganese residues fineness, be stained with it and can't compare the mill output height; 4, balling-up plasticity is good; 5, operation is convenient in the kiln calcining, because electrolytic manganese residues contains the composition of vitriol; 6, electrolytic manganese residues contains 2% manganese through high-temperature calcination in the manganese slag, and 10% ammonia decomposes fully; 7, color of clinker is a black, and cement market is good.
In a word: to the application of electrolytic manganese residues, not only reduced environmental pollution, keep consumption ground simultaneously, also be that manufacture of cement has found new resources, electrolytic manganese residues is turned waste into wealth, for the electrolytic manganese Sustainable Development of Enterprises has played certain strong backing effect, crucial meaning is arranged for solving " manganese triangle " pollution.
