Abstract
The invention discloses a preparation process for a kaolin ceramic using waste heat of exhaust gas for drying. According to the process, kaolin is used as a raw material, and 17 process flows consisting of selection and batching of materials, ball milling, iron removal and sieving, squeezing to obtain a cake, aging, refining and evacuation, compressing and molding of a blank, drying, polishing, glazing, external glazing, inspection, placing on a rack, appliquing, filling of a blank, sintering and selection and packaging of ceramics are carried out to realize preparation of the kaolin ceramic. According to the preparation process for the kaolin ceramic, in the process flow of drying of the blank, waste heat of roasting is utilized for heat supply, consumption in a traditional carbon burning process is completely replaced by the waste heat, and thus, energy is saved and production cost for a ceramic product is reduced; appliquing is carried out after drying, then one-step sintering is carried out, so one process flow of sintering is omitted and manpower and the energy source coal are saved.
