Abstract
A method for producing moldings, in particular briquettes, from fine-grained to medium-grained mixed material using organic binders. In a first stage, the mixed material is heated to a temperature necessary for the molding operation. In a second, atmospherically separate stage, mixing of the mixed material with binder is performed, as well as downstream steps of the process. The method allows hazardous emissions to be avoided.
Claims27
A method for producing moldings from fine-grained to medium-grained mixed material using organic binders, comprising a first stage of heating the mixed material to a temperature necessary for the molding operation and a second of mixing the mixed material with binder, and then downstream steps of the process of molding, wherein the second stage is atmospherically separate, and under a pressure that is lower than the pressure in the first stage and/or and the surrounding pressure, wherein the fine-grained to medium-grained mixed material has on average grain sizes of 0.01 to 5 mm.
