DEG C, glaze slip temperature is 45 DEG C -50 DEG C in the specific whole process such as glaze slip.Further, glaze slip ball milling and conveying,
Cooling measure is used during aging, and glaze slip temperature in the whole process of glaze slip is made to be no more than 50 DEG C, glaze slip performance is stablized,
Produce glazing defect sharp fall.
It further include to progress shower water outside ball mill, specifically, the present invention exists during ball milling mixing of the present invention
Water pipe is installed, in glaze slip ball milling, dress is cooled down using shower water outside ball mill, is further ensured that glaze slip exists above ball mill
Glaze slip temperature is no more than 50 DEG C when ball milling, improves the stability of technique, and the control of glaze slip temperature, which is no more than 50 DEG C, makes additive carboxylic
Methylcellulose CMC rotten problem will not occur because glaze slip temperature is too high.
In addition, glaze slip blowing out of ball mill is sent to stock tank and requires to use compressed air, it is dry that air specifically can be used
Filtering is dried to compressed air in dry machine (workshop uses De Gang Industrial Co., Ltd DK-100AA model), monthly regularly replaces
Drying machine filter core.The present invention is dried filtering by air and avoids bringing oil, water or other impurity into because of compressed air, pollutes glaze
Slurry.
Below by specific embodiment, further description of the technical solution of the present invention.
