| Fiber cement material, which contains organic fibers, is used as an additional raw material for the production of cement clinker. The cement clinker is produced in a system which comprises a cyclone tower (11) and a rotating drum kiln (15). The cyclone tower (11) comprises cyclones (1-5) and a pre-calciner unit (10) wherein fuel is combusted to feed the cyclone tower with heat. The raw clinker meal is passed through the cyclone tower to preheat it. By the combustion of the fuel in the pre-calciner unit (10) a hot zone is produced in the cyclone tower wherein the raw clinker meal is calcined. In order to be able to add larger amounts of the fiber cement material without causing a too high total organic carbon content of the exhaust gasses and/or without causing depositions of organic matter onto the inner walls of the cyclone tower (11), the organic fiber cement material is added in a dry powdered form in said hot zone, in particular in the pre-calciner unit (10) to be heated in less than 5 seconds to a temperature of at least 800° C. | ||||||

| 35 | Process of treatment and environment-friendly utilization of asbestos-cement products | US492727 | 1995-06-20 | US5676750A | 1997-10-14 | Gert Gleichmar; Joachim Kieser; Stefan Ambrosius; Helmut Gormar; Arno Krahner; Wolf-Joachim Buhrandt |
| The invention refers to a process of treatment and environment-friendly utilization of asbestos-cement products including a thermal process to transform the asbestos component. Inventively, this is achieved by a coarse reduction of the asbestos-cement products under black side conditions with maintained vacuum. Then, the material is ground to asbestos-cement meal and fed to the flame zone of the rotary kiln of a cement clinker production line. Depending on the fuel type used, the portion of fed asbestos-cement meal varies between 2 and 5%, related to the amount of cement raw meal, substituting 2 to 5% of the cement raw meal mix at a time. The thermal transformation of the asbestos component takes place with temperatures of approximately 1800.degree. C. in the burner zone. The modified residual substance becomes a constituent of the cement clinker due to assimilation in the kiln charge. | ||||||
