10. A mixing method using the solid-liquid mixing apparatus according to any one of claims 1 to 9, characterized in that: the method comprises the following steps:
s1: the driving mechanism (22) is started to drive the rotating shaft (20) to rotate, liquid enters the dispersing cylinder (10) from the liquid feeding hole (11) and falls onto the dispersing disc (30), and the dispersing disc (30) drives the liquid to rotate along with the rotation of the rotating shaft (20) to form a water curtain and has a certain speed;
s2: solid particles enter the dispersion cylinder (10) from the solid feed inlet (12) and are premixed with the falling liquid;
s3: the material formed by solid particles and liquid falls onto the movable grinding disc (41) and flows onto the static grinding disc (42) along the first slit (45) under the action of gravity;
S4: the materials are ground under the action of the first grinding bulges (43) and the second grinding bulges (44), and flow out of the second slits (46) along with the increase of pressure to fall to the bottom of the dispersing cylinder (10) and enter the inside of the fixed sleeve (50) through the feeding through hole (52);
S5: the spiral auger (21) lifts the materials upwards, and the flowing speed of the materials is increased along with the gradual reduction of the diameters of the fixed sleeve (50) and the spiral auger (21) and the materials are sprayed out from an overflow port (51) of the fixed sleeve (50);
S6: the materials are sprayed on the movable grinding disc (41), flow onto the static grinding disc (42) through the first slit (45), are ground under the action of the first grinding protrusion (43) and the second grinding protrusion (44), flow to the bottom of the dispersion cylinder (10) from the second slit (46), flow into the fixed sleeve (50) through the feed through hole (52), are lifted by the spiral packing auger (21) to be dispersed and ground again, and the step is repeated;
S7: after the particle size of the material reaches a preset value, the driving mechanism (22) is closed, the rotating shaft stops rotating, the valve (14) is opened, and the material is discharged from the discharge hole (13).
