REORGANIZATION OF THE RUBELAND LIME-WORKS WITH PARTICULAR REGARD TO PROCESSING THE SMALL-SIZE LIMESTONE

The example of the Rubeland lime works is used to describe the change from an uneconomic producer of hard-burnt lime for the carbide industr y to a cost-effective producer of limestone and lime products with a w ide product range. Full utilization (put into effect after German re-u nification) of the limestone material extracted in the quarry includin g utilization of the stockpiled material from earlier years, is illust rated with aid of process and quantity pow sheets. The small-size lime stone is now processed in a Marz kiln for small-size limestone, in the production of limestone meal, grit and chippings for flue gas desulph urization, and in the production of limestone sands for ore preparatio n in the steel industry. A report is also given of the environmental f riendliness and resource conservation of the present production system .
