This important book will make an excellent addition to anyone involved in the drying of ceramic materials. In order to accommodate readers with a wide range of interest and abilities, most chapters are divided into sections by basic and advanced concepts. Selected chapters include introduction to drying; water, air, and water vapor; drying mechanisms in particulate systems; psychrometry; characterization of dryer operations; dryer control; drying defects; and advanced drying technologies. The book contains problems at the end of each chapter (with answers to selected problems in the appendix) and laboratory exercises.
