Abstract

The invention discloses a method for utilizing waste press mud in a ceramic plant on a large scale to prepare a ceramic tile blank and a product. The method comprises the steps that 1, raw materials are weighed and mixed, and a ball mill wet method is adopted to smash the raw materials into mud slurry; 2, after the mud slurry passes through a 50-100-mesh screen, atomizing and drying are conducted,and then the mud slurry passes through an 8-16-mesh screen to obtain powdery blank with the water content of 6.5-7.0%; 3, the powdery blank is aged for 48 or more hours and then is delivered to an automatic tile press to be compress-molded; 4, the formed blank is put into a roller dryer, and after drying is conducted at 130-160 DEG C for 1-2 hours, a glaze technology of executing glaze spraying and printing and conducting glaze spraying again is conducted on the surface; 5, then the blank is put into a roller kiln, and at the temperature of 1,170-1,190 DEG C, calcining is conducted for 60-90min; 6, then after being trimmed, tested and sorted, the blank is warehoused. Waste press mud in the ceramic plant can be recycled on a large scale, and it is achieved that waste is utilized.

Description

technical field [0001] The invention belongs to the technical field of building ceramic materials, and in particular relates to a method and a product for preparing ceramic brick embryo bodies by using waste squeezed mud from ceramic factories in large quantities. Background technique [0002] Ceramic tiles are plate or block ceramic products produced by mixing, grinding, powdering, molding, sintering, edging or polishing of clay and other inorganic non-metallic raw materials. In the process of producing ceramic tiles, a large amount of waste solid substances will be produced, mainly rotten tiles and waste squeezed mud. According to the survey, the production of the former generally accounts for 0.5% to 1.5% of the total consumption of raw materials in ceramic factories. The powder is re-added to the formula for use; and the latter (that is, waste squeezed mud, which is the waste solid matter after water treatment, deep sinking, and squeeze recovery of industrial sewage cont...
