Abstract
Research is done to analyze work performance of extruder machine to compress clay for red brick. The
analyzing work performance of extruder machine is based on dry density of clay and water content. Research is done in
industry and laboratory with doing observation and taking specimen of clay that had been given treatment in extruder
machine. And based on analyzing data it shows that dry density of clay in extruder machine is in range 1.45 gram/cm3 –
1.55 gram/cm3 and water content can be range 27% -31%.
