Abstract
A system () and method to control rheology of ceramic pre-cursor batch during extrusion is described herein. An extrusion system () comprises an extruder () with an input port () configured to feed ceramic pre-cursor batch into a first section () of an extruder barrel and a discharge port configured to extrude a ceramic pre-cursor extrudate () out of the extruder barrel downstream of the input port (). A liquid injector () is configured to inject liquid into the ceramic pre-cursor batch. A sensor () is configured to detect a rheology characteristic of the ceramic pre-cursor batch. A controller () is configured (i) to receive the rheology characteristic from the sensor (), (ii) compare the rheology characteristic to a predetermined rheology value of the ceramic pre-cursor batch, and (iii) generate a command based on the comparison. A liquid regulator () is configured to receive the command and adjust liquid flow to the liquid injector () based on the command.
