The invention discloses a tower mill for fine grinding and ultrafine grinding. The mill comprises a grinding bin, a main shaft, a stirring part and a driving assembly; a grinding space is formed in the grinding bin; the main shaft is arranged in the grinding space, the driving assembly is used for driving the main shaft to rotate, the stirring part spirally winds the main shaft, the thickness of the stirring part is gradually increased in the direction away from the main shaft, the first end of the main shaft is connected with the driving assembly, the second end of the main shaft and the inner wall of the grinding space are arranged at intervals, and the second end is located below the first end. The invention discloses the tower type mill for fine grinding and ultrafine grinding. The thickness of the stirring part is gradually increased along the direction far away from the main shaft, so that shearing force borne by external materials is larger, and the normal lifting effect is better; under the condition
