AbstractAbout AuthorsReferences
The rational methods for raw material preparation in the wall ceramics technology of compression molding are formulated. It is established that for the low-quality clay raw materials and industrial waste the grinding up to class -0.3 +0 mm is required. The best packaging of the fine-dispersed raw material during the molding is achieved through its preliminary aggregation in the mixer-granulators of intense action. It is found that at optimal molding pressures in the process of adobe compaction before the plastic deformation of granules at their boundaries the concentration of the liquid phase takes place due to the squeezing moisture out of the granules that contributes to sintering of the product during burning. In the industrial conditions the possibility for production of an effective facing ceramic brick by compression molding from low-quality raw material and industrial wastes with an optimal stricture, high mechanical and decorative qualities is confirmed.
