The invention relates to a standardized continuous treatment method of a ceramic raw material and a production line thereof, wherein the production line comprises a sandstone feeding unit, vertical mill rough machining equipment, a continuous bowl mill unit, pulpifying equipment, an iron removing pool, a bowl mill and a spray drying tower. The sandstone is conveyed to the vertical mill rough machining equipment by the sandstone feeding unit according to a ratio requirement, and is continuously and steppedly ball-milled after the sandstone is coarsely broken below 1mm of fineness, and the slurry below 0.1mm of granularity after ball milling is conveyed to the iron removing slurry pool to remove iron and whiten; and various raw ore mud, after conveyed to the pulpifying equipment by the sandstone feeding unit according to a ratio requirement to remove the sand and impurities in the raw ore mud, and pretreated sandstone slurry are stirred in a big slurry pool, and finally the mixed slurry is conveyed to the bowl mill, and is spray-dried by the spray drying tower until the mixed slurry is ball-milled to 0.05mm. The invention provides the standardized continuous treatment method of the ceramic raw material with advantages of high ball milling efficiency, low energy consumption, stable powder component, high whiteness and low cost, and the production line thereof.
