Prototyping of Ultrasonic Die for Extrusion of Ceramic Brick

Resumo

A scaled-down prototype of a die for extruding ceramic brick with ultrasonic oscillations from a magneto-striction transducer delivered onto the die wall was tested. Extruder productivity was increased. There is a complex improving effect on the microstructure of the ceramic, drying properties, shrinkage, water absorption, and density and strength, making it possible to reduce the plasticity requirements of clay. The test result shows that it is possible to develop an ultrasonic die for industrial extruders.
