Avoidance of damage due to strength-reducing reactions in the preheating zone of tunnel kilns

4 Expansion and shrinkage processes In a tunnel kiln firing process for heavy clay products, there should be no mutual contact between the wares to be fired, and all exposed surfaces within and around...

1 Context and formulation of problem Low-temperature drying is a modified form of open-air drying with the aid of modern plant and control technology. In heavy clay production, the introduction of...

1 Introduction The increased demands in terms of the quality of vertically perforated bricks call for the brick industry to manufacture products with very good thermal insulation properties and...

5. Characterization of the dried brick bodies »Table 8 shows the shrinkage, packing density and bending strength of the dried brick bodies. The shrinkage of the basic bodies varies between 7.6 and...

1 Context The particle-size distribution of raw materials employed is one of the most important parameters with respect to workability, drying and firing behaviour and pore-structure formation within...
