D, the mud cake segment of extending that will superpose last time are superimposed as the 30-60mm height, extend by highly gradually low roller roll extrusion once more, and the mud cake of 5-20mm is extended in roll extrusion;

E, like this stack, roll extrusion alternate cycles twice at least that extends reach to the predetermined color interval and the number of plies until mud cake;

F, the mud cake after above-mentioned roll extrusion extended segment again are superimposed as the high mud buttress of 50-70mm and carry out highly gradually low roll extrusion and extend, and form the thick mud cake of 35-45mm;

G, the mud cake that 35-45mm is thick are cut into the thick slice of 3-6mm through slicer, and slice enters the drier drying;

H, drying back moisture content are the broken screen(ing) machine fragmentation of slice process of 7%-9% and sieve that getting particle diameter is the particle of 1-6 mesh sieve, is used from the especially big particulate ceramic adobe that is pressed into Gorgeous Colouring in order to the powder one with Ceramic Tiles.

Further, the charity of pug, roll extrusion, extension and section can adopt mud extruder, conveyer belt, roll extrusion roller and slicer to realize that mud extruder, roller and slicer are arranged on the conveyer belt successively, and the roller of circulation roll-in has three groups at least.And the speed that conveyer belt carries mud cake is consistent with the linear speed that mud extruder squeezes mud speed and roller, and adjustable extent is 0.5-7m/min.

Below in conjunction with drawings and Examples content of the present invention and advantage are done deeply explanation.
