Objetivo TO OBTAIN SCIENTIFIC UNDERSTANDING OF THE DRYING PROCESS IN ORDER TO OPTIMIZE THE INDUSTRIAL PROCESS AND TO ACHIEVE A RATIONAL USE OF CLAYS. THIS "DRYING" WORK INCLUDES: 1. ANALYSIS OF THE PROPERTIES OF CLAY MINERALS AT THE DRYING STAGE ON SINGLE OR MIXED TYPES OF CLAYS: - SORPTIOMETRY: THERMODYNAMIC AND PHYSICAL STUDY OF THE CLAY-WATER SYSTEM; - STUDY OF THE REPERCUSSIONS OF MODIFYING THE CLAY WATER SYSTEM: EXAMINATIONS OF DIMEN,ENSIONAL DEVELOPMENT AND RHEOLOGICAL BEHAVIOUR AS A FUNCTION OF WATER CONTENT. 2. STUDY OF THE DRYING PROCESS IN THE MATERIALS A STUDY SIMILAR TO THE ABOVE WILL BE CARRIED OUT ON TYPICAL MATERIALS BY ANALYSIS OF THE FORMATION AND EVOLUTION OF MOISTURE GRADIENTS AND ON THE EFFECTS OF THE METHOD OF CIRCULATING THE DRYING AIR. AT HIS STAGE OF THE WORK THE FOLLOWING WILL BE DEFINED: - A METHOD OF DETERMINING OPTIMUM DRYING OF A GIVEN MATERIAL; - THE NETHODS FOR ADOPTING A MATERIAL (PRINCIPLE OF CHOICE AND CONDITIONS OF THE USE OF CLAY MINERALS). 3. EXAMINATION OF THE DRYING OF PRODUCTS EXAMINATION OF THE DRYING BEHAVIOUR OF TYPICAL PRODUCTS AND CONTROL OF THEIR PROPERTIES AFTER TREATMENT. THIS RESEARCH PROJECT IS PART OF A COMMON PROGRAMME THAT HAS BEEN DRAWN UP BY SEVERAL WELL-EQUIPPED RESEARCH CENTRES IN THE COMMUNITY TO WORK ON A CERTAIN NUMBER OF RAW MATERIALS. THE RESEARCH HAS BEEN DISTRIBUTED AS FOLLOWS: MINERALOGICAL ASPECTS - FRG, MSA-202-D SHAPING, RHEOLOGY - BELGIUM, MSA-208-B; HOLLAND, MSA-207-NL DRYING - FRANCE, MSA-203-F, MSA-204-F FIRING - UNITED KINGDOM, MSA-211-UK PROPERTIES OF FINISHED PRODUCTS - ITALY, MSA-206-I.
