Abstract
Authors present the description of the experimental plant based on the auger vacuum extruder at the enterprise for brick production and designed to assess the adequacy of the developed mathematical model of the process of the plastic shaping of the ceramic mixture. The main difficulty in carrying out the comparative analysis is that the shear rate of the ceramic mixture in the extruder pressure head has been taken for the basic output coordinate of the created model. It most fully characterizes the shaping process focused on the production of brick of specified durability. There is no possibility to measure directly on the production unit. To overcome this problem in the structure of the shaping process model pressure of the ceramic mixture behind the extruder protruding blade has been chosen as an additional coordinate. The technique of carrying out experiments is given. Comparison of transient formation pressure obtained on the operating plant and on the model has been made. It is established that their divergence has made 5.2% and that confirms the adequacy of the mathematical model for the ceramic mixture shaping in the auger vacuum extruder.
