ABSTRACT:
A process and installation for the production of powdered, surface-active agglomeratable, calcined material, specifically calcined lime, from material or raw material present in the form of sludge, scum or the like, such as the waste materials in the sugar industry. The specific example of the process is production of calcined lime and/or usable CO.sub.2 from waste materials existing in the sugar producing industry. The process includes reacting the raw materials in a special mixing chamber under controlled time and temperature conditions, preheating the materials by using the reaction exhaust gases, obtaining calcined lime particles isolated from CO.sub.2 gases, and recycling portions of the particles to obtain complete reaction of the material. The process provides calcined lime which can be discharged in solid form or converted through further stages to lime-milk for direct use in sugar making processes. A proposed installation includes various pieces of equipment such as a combustion chamber, a special calcining or reaction chamber which provides parallel flow paths with a turbulent vortex zone within which the raw materials, preferably preheated, are subjected for controlled periods to desired reaction temperatures, various preheaters, dust separators and final storage or mixing units, all units disclosed in an inter-related flow path arrangement for an exemplary installation by which the process can be carried out.
