Plug mill: is a machine for mixing, compressing and recuperating clay. They are run by electricity and made in many different shapes and sizes and important if you work with large quantities. Clay must not be too dry to put through the plug mill, which will recondition and consolidate it so that it can be used again and also improves its strength and workability. There are plug mills for producing both large and small quantities. The name now more commonly used for this machine is extruder.
