Embodiment 1

[0028] Get the following weight percentage mud raw material:

[0029] Prepare wool porcelain and underglaze multicolored porcelain mud according to the following formula (all raw materials are industrial grade): kaolin 55%, bauxite 5%, calcite 10%, quartz stone 10%, wollastonite 5%, albite feldspar 10% %, dolomite 5%, the sum of the component percentages is 100%.

[0030] Using conventional wet ball milling, put the above-mentioned raw materials in the weight ratio into a ball mill, then add water, the ratio of material: ball: water is 1:1.5:0.5, and ball mill for 18-20 hours to obtain a slurry. Slurry passes through a 300-mesh sieve, and is filtered with a stainless steel vibrating screen with a 350-mesh filter. The super-strong iron absorber is used to filter and absorb iron, and the iron is absorbed repeatedly for 3 times. The hydraulic K75 press is used to squeeze the mud, and the water content is between 24% and 26%. between. Use an all-stainless steel mud refining mach...
