In the whole production process of the domestic ceramics, the drying can be divided into primary drying and secondary drying. The primary drying generally refers to belt die drying, that is, drying after the mud blank is subjected to roll forming, and after the primary drying, the strength and the water content of the blank body need to meet the requirements of demoulding. There are many drying methods such as fan drying, microwave drying, infrared drying, natural drying, etc. for primary drying.
