| Manufacturing process of a sulfoaluminate or ferroaluminate cement, cement obtained by this process, and installation for implementation. The invention concerns a manufacturing process of cement (1) from a mixture (2) containing CaCO3, Al2O3 and/or Al(OH)3, CaSO4, SiO2 and/or a product containing silica or silicates such as clay, these compounds being present in the anhydrous or hydrated form, individually or in combination. This process is characterized in that the mixture (2) is treated up to clinkering by movement in a center (3) of kiln (4), in a sheet (5) with approximately constant thickness, at approximately constant speed, along a treatment path (6) subjected to a positive temperature gradient, and for a treatment time during which this mixture (2) remains below its melting temperature, and in that the clinkered mixture (7) is cooled upon exit from the treatment path (6). | ||||||
| 27 | High iron oxide hydraulic cement | US598411 | 1975-07-23 | US4036657A | 1977-07-19 | Povindar K. Mehta |
| Hydraulic cements having higher (about 5%) iron-oxide content and lower (43-57%) than the usual calcium-oxide content of Portland cements are disclosed. These high iron-oxide cements have normal setting times, but high early strengths that develop without resorting to fine grinding or steam curing. The cements can be produced with considerably less expenditure of energy than required for conventional Portland cements due to lower burning temperatures and reduction in the amount of calcium-oxide which requires the greatest energy input for preparation of the cements. | ||||||

| According to prior art, making aluminous ferrugineous cement would involve only the use of a shaft kiln coupled with the melter. A high energy consumption and a low power installation are disadvantages. The new method is designed to allow aluminous ferrugineous cement to be made by sintering in a rotating pipe-still. In order to increase the sintering interval during the raw meal mixture sintering process up to a temperature of 100<0> C, an auxiliary sintering agent is added as a reductant. Said reductant can be added to a raw meal mixture consisting of limestone and aluminous ferrugineous components. But it is also possible to have the raw meal mixture reacted in the presence of a decrease-controlled flue gas atmosphere. The inventive method enables the phase contents, more especially the ratio 12 CaO x 7 Al2O3/CaO x Al2O3/CaO x 2 Al2O3, to be set accurately and optimized depending on the use of the product. | ||||||

| A high iron content cement is formed principally from two industrial by-products which are available in very large quantities, (1) cement kiln dust, or CKD, and (2) the Red Mud which is a by-product of the extraction of alumina from bauxite ore. Smaller quantities of lime (calcium oxide) and gypsum (calcium sulfate) and aluminum oxide as needed, are added to the CKD and Red Mud, and the mixture is heated to between about 1250 degrees C. and 1400 degrees C., substantially lower than the kiln temperature for Portland cement. The resultant clinker is pulverized to form a lightweight, fast setting, strong, hydraulic cement. | ||||||
