In the wet process, the mud cake needs to be dewatered by a long time of pressure filtration, and after drying, it is dried by a special drying equipment to dry the kiln. Therefore, the dewatering and drying time is long and the drying is complicated. Recently, a new technology for drying mud cakes was invented overseas. The idea of ​​the invention is novel and ingenious. An extremely simple drying process is adopted. That is, the spray-dried material is used as the dried cake of dewatering, mud-retaining and drying lines, and is added to the mud cake for drying when the mud is practiced. The biggest advantage is that in the process of filter press dewatering, the moisture content of the mud cake is fully reduced, the dewatering time can be shortened, no special drying equipment is needed, the process of the original dry mud cake is omitted, the efficiency of the blank preparation is improved, and the utility model is simple and practical. Save time and money, the effect is significant.
