The invention discloses a preparation method of
ceramic tile bottom blank
powder. The preparation method comprises the steps that S310, multiple kinds of toner are pre-mixed; and S320, a mixing channel is formed in a material mixing
barrel, an opening in one end of the mixing channel serves as a feeding port, the mixing channel inclines downwards in the direction away from the feeding port, a plurality of overflow through holes are formed in the
peripheral wall of the material mixing
barrel, the material mixing
barrel is rotated, the multiple kinds of pre-mixed toner are conveyed into the mixing channel from the feeding port, the toner is continuously collided and mixed along with the rotation of the material mixing barrel and falls downwards through the overflow through holes to be collected, the discharged bottom blank
powder is in a
random mixing state, after the bottom blank
powder is pressed and formed through a subsequent pressing
machine, a
brick bottom blank with a whole-body effect is formed, the
mixing effect is good, the color and the texture are similar to those of the surface, the texture texture is improved, the aesthetic property and the use effect are improved, and the operation difficulty and the
production control difficulty are greatly reduced.
