[0029] The use method and advantages of the utility model: When the ceramic lining granulating device is used, the working process is as follows:

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, first, the operator can add ceramic powder, binder and other additives into the mixing barrel 2 through the feed hopper 1 in sequence, and then add an appropriate amount of water or solvent through the liquid adding pipe 12.

The through hole 601 at the top is opened to form a strip material discharge, and at the same time, the third motor 901 can be started to drive the moving screw 902 to rotate.

The strip material is cut into particles by moving horizontally along the bottom of the extruder barrel 6, and the cut particles pass through the pelletizing box 8 and enter the inside of the pelletizing barrel 10, and then the electric heating tube 1002 arranged in the inner wall interlayer of the pelletizing barrel 10 is started to heat and dry the particles in the pelletizing barrel 10.
