The invention relates to a quality control method for the production of green bodies of wall and floor tiles. The method includes the following steps of: (1) feeding: a mud and sand material is selected, the process parameters of the mud and sand material are measured and controlled, and chemical analysis is carried out; (2) compounding: the moisture content of the mud and sand material is detected, the mud and sand material is compounded with chemical materials according to the moisture content, and the accuracy of compounding is checked; (3) ball milling; (4) spray drying: the preset valuesof the operation of a spray tower are set and checked, spray drying is performed, so that powder or micro-powder is obtained, and the process parameters of the powder or micro-powder are measured andcontrolled; and (5) material conveying: the powder or micro-powder is conveyed to a press, and the moisture content is measured and controlled before the material is used. According to the quality control method of the invention, the step of ball milling further comprises the following steps that: a, the cleanliness of the interior of a ball mill is checked, and ball milling is performed, so thata slurry can be obtained; b, the process parameters of the slurry are measured and controlled, and the slurry is arranged into a transfer cylinder or a slurry tank; and c, the slurry feeding pressureof the transfer cylinder, and the iron removal quality of the slurry and the process parameters of the slurry in the transfer cylinder are measured and controlled, and the process parameters of the slurry in the slurry tank are measured and controlled. The quality control method of the present invention has the advantages of high control quality, low scrap rate and convenient control.
