Part 1 and 2 of this article provide an overview of the grinding of bricks and the influencing factors. The appropriate grinding tool depends on the characteristics of the brick. In practice, it is chosen by experienced testers and the choice is often an emotional one. So the idea was to carry out a preliminary systematic test in the laboratory regarding the machinability of fired raw material and to analyse the influence of the raw material and the firing temperature on the grinding of bricks. For this purpose, a test method was developed at the company Lingl. With the application of this method, the machinability of laboratory samples always produced under the same conditions is quantitatively determined and thus evaluated independently of the tester. First results of this method are listed here in part 2 and compared to results from the field.

Up to now, an increase in the porosity in heat-insulating backing bricks has been limited by the burn-out of the organic matter contained within the raw materials during a small temperature range in the preheating zone, leading to unusable energy release. This can sometimes lead tojjncontrollability in the tunnel kiln. Within the framework of a research project Hans Lingl GmbH is developing a firing technology that guarantees safe process management when firing high-energy raw materials. The results achieved to date and the new Lingl PoroControl Technology are presented.

In this paper the resource efficiency of the use of secondary raw materials was studied. Their increased use is regarded as a future-viable instrument for improving productivity while taking consideration of ecological concerns. Accordingly, the use of secondary raw materials is only sensible when the material flows moved overall are not increased but reduced where possible. For this reason, with the help of a material intensity analysis, the environmental impact intensities of the use of secondary raw materials were evaluated based on the specific consumption of resources with reference to one example, it is shown that the consumption of resources can be reduced substantially with the use of secondary raw materials in the form of natural stone powder. Owing to the transport-related resource consumption, optimum reduction is achieved when externally sourced clays for which transport costs are also incurred are substituted by the secondary raw materials. In addition to the change in the energy required for firing that has only analysed up to now, the evaluation covers all process steps involved in production (preparation, shaping, drying, firing, transport). With the application of material intensity analysis, it could be shown that the resource efficiency of ceramic products can be increased considerably with the use of secondary raw materials.

The issue of energy saving is of major importance for the ceramics industry. In addition, analysis of the respective resource consumption is shifting increasingly into the focus of interest [1,2]. Sensible utilization of industrial waste in ceramic bodies in energy, economic and ecological terms requires knowledge of the energy and raw material consumption as well as the CO2 emissions for the manufacture of ceramic products. From this, potential savings for the use of secondary raw materials as well as for an efficient use of resources can be derived.
