In the extrusion process, highly viscous, a plastic mix of ceramic powder with additives (with a consistency that of potters clay) is forced through a shaped die with high force. This is similar to squeezing frosting out for cake decoration. There are Two Types of Extruders.
11.25 Clay Processing
Figure 11.25-4 illustrates the process flow for fire clay processing. Mined fire clay first is transported to the processing plant and stockpiled. In some cases, the crude clay is weathered for 6 to 12 months, depending on the type of fire clay. Freezing and thawing break the material up, resulting in smaller particles and improved plasticity.
